COPYRIGHT NOTICE

[0002] A portion of the disclosure of this patent document contains material which is subject to copyright protection.

TECHNICAL FIELD

[0003] The present disclosure relates to a drilling system for forming a borehole in an earthen formation, and in particular to a drilling system and a method for monitoring drilling parameters for an underground drilling operation.

BACKGROUND

[0004] Underground drilling, such as gas, oil, or geothermal drilling, generally involves drilling a bore through a formation deep in the earth. Such bores are formed by connecting a drill bit to long sections of pipe, referred to as a "drill pipe," so as to form an assembly commonly referred to as a "drill string." The drill string extends from the surface to the bottom of the bore. The drill bit is rotated so that the drill bit advances into the earth, thereby forming the bore. In rotary drilling, the drill bit is rotated by rotating the drill string at the surface. A mud motor can be used to rotate the drill bit as is known, In general, optimal drilling is obtained when the rate of penetration ("ROP") of the drill bit into the formation is as high as possible while vibration of the drilling system is as low as possible. Rate of penetration is a fUnction of a number of variables, including the rotational speed of the drill bit and the weight on-bit ("WOB"). The drilling environment, and especially hard rock drilling, can induce substantial vibration and shock into the drill string, which has an adverse impact on drilling performance.

Vibration is introduced by rotation of the drill bit, the motors used to rotate the drill bit, the pumping of drilling mud, and imbalance in the drill string, etc. Vibration can cause premature failure of the various components of the drill string, premature dulling of the drill bit, or may cause the catastrophic failures of drilling system components. Optimal drilling should account for the vibration of the drilling system and the impact such vibration can have on various operating parameters or drill string components. The drilling environment, as well as vibration of the drilling system during a drilling operation, can make it difficult for a drill rig operator to ensure that drilling parameters are operating as expected or optimally.

SUMMARY

An embodiment of the present disclosure is a drilling system for forming a borehole in an earthen formation. The drilling system can include a drill string configured to rotate so as to form the borehole in an earthen formation during a drilling operation. The drill string can operate according to one or one or more drilling parameters so as to form the borehole.

The drilling system can include a plurality of sensors configured to obtain drilling data during the drilling operation, the drilling data being indicative of the one more drilling parameters, at least one of the plurality of sensors supported by the drill string. The drilling system can also include a computing device configured to determine a first plurality of operating ranges for the one or more drilling parameters of the drilling operation based on the drilling data obtained from the plurality of sensors. The first plurality of operating ranges can be based on a first duration of time operating the drill string during the drilling operation. The first plurality of operating ranges include at least one preferred operating range for each of the one or more drilling parameters and at least one less preferred operating range for each of the one or more drilling parameters. The computing device can also be configured to determine a second, updated plurality of operating ranges for the one or more drilling parameters. The second, updated plurality of operating ranges based on a second duration of time operating the drill string that is subsequent to the first duration of time, the second, updated plurality of operating ranges include at least one preferred operating range and at least one less preferred operating range for each of the one or more drilling parameters. The at least one preferred operating range of the second, updated plurality of operating ranges can be different than the at least one preferred operating range for the first plurality of operating ranges. The computing device can include a user interface, such as graphical user interface, that is configured to display on a computer display a visual indication of the first plurality of operating ranges for the one or more drilling parameters The user interface is configured to display subsequent to the first duration of time, a visual indication of the second, updated plurality of operating ranges for the one or more drilling parameters.

[0006] Another embodiment of the present disclosure is a computer implemented method, system and a non-transitory, tangible computer readable medium for monitoring and displaying one or more drilling parameters for a drill string operating to form a borehole in an earthen formation. The method includes determining, via a computer processor, a first pura1ity of operating ranges for the one or more drilling parameters for a drilling operation. The first plurality of operating ranges can be based on a first duration of time operating the drill string during the drilling operation. The first plurality of operating ranges include at least one preferred operating range for each of the one or more drilling parameters and at least one less preferred operating range for each of the one or more drilling parameters. In response to the step of determining the first plurality of operating ranges by the computer processor, the method can include displaying, via a graphical user interface on a computer display, a visual indication of the first plurality of operating ranges for the one or more drilling parameters. The method includes determining, via the computer processor, a second, updated plurality of operating ranges for the one or more drilling parameters. The second, updated plurality of operating ranges can be based on a second duration of time operating the drill string that is subsequent to the first duration of time. The second, updated plurality of operating ranges include at east one preferred operating range and at least one less preferred operating range for each of the one or more drilling parameters. The at least one preferred operating range of the second, updated plurality of operating ranges can be different than the at least one preferred operating range for the first plurality of operating ranges. In response to the step of determining the second, updated plurality of operating ranges, the method can display, via the graphical user interface on the computer display, the second, updated plurality of operating ranges the one or more drilling operation parameters.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

[0020] Referring to FIG. 1, a drilling system or drilling rig 1 is configured to drill a borehole 2 in an earthen formation 3 during a drilling operation. The drilling system I includes a drill string 4 for forming the borehole 2 in the earthen formation 3, and at least one computing device 100. The computing device 100 can include one or more software applications. The computing device 100 and the one or more software applications execute various methods for monitoring the drilling operation, controlling the drilling operation, and displaying information concerning the drilling operation as ifirther detailed below, While the borehole 2 is illustrated as a vertical borehole, the systems and methods described herein can be used for directional drilling operation. For instance, the drill string 4 can be configured to form a borehole 2 in the earthen formation 3 a portion of which orientated along a direction that is transverse to an axis that is perpendicular to the surface II of the earthen fonnation 3.

[0021] Continuing with FIG. 1, the drilling system or rig 1 includes a derrick 9 supported by the earth surface ii. The derrick 9 supports the drill string 4. The drill string 4 has a top end 4a, a bottom end 4b, a top sub 45 disposed at the top end 4a of the drill string 4, and a bottomhole assembly 6 disposed at the bottom end 4b of the drill string 4. The drill string 4 can also include multiple sections of drill pipe (not shown) connected together to form the drill string. The bottomhole assembly 6 includes top end 6a and a bottom end 6b. A drill bit 8 is coupled to the distal end 6b of a bottomhole assembly 6. The drilling system 1 has a prime mover (not shown), such as a top drive or rotary table, configured to rotate the drill string 4 so as to control the rotational speed (RPM) ot and torque on, the drill bit 8. Rotation of the drill string 4 and drill bit 8 thus defines the borehole 2. As is conventional, a pump 10 is configured to pump a fluid 14, for instance drilling mud, downward through an internal passage in the drill string 4. After exiting at the drill bit 8, the returning drilling mud 16 flows upward to the surface II through an annular passage formed between the drill string 4 and the borehole 2 in the earthen formation 3. A mud motor 40, such as a helicoidal positive displacement pump or a "Moineau-type" pump, may be incorporated into the bottomhole assembly 6. The mud motor is driven by the flow of drilling mud 14 through the pump and around the drill string 4 in the annular passage described above. The mud motor can rotate the drill bit 8.

[0022] A drilling operation as used herein refers to one or more drill runs that define the borehole 2. For instance a drilling operation can include a first drill run for defining a vertical section of the borehole 2, a second drill run for defining a bent section of the borehole 2, and a third drill run for defining a horizontal section of the borehole 2. More or less than three drill runs are possible. For difficult drilling operations, as many as 10 to 15 drill runs may be completed to define the borehole 2 for hydrocarbon extraction purposes. It should be appreciated that one or more bottomhole assemblies can be used for each respective drill run.

The systems, methods, software applications as described herein can be used to execute methods that monitor and control the drilling operation, as well as monitor and control the specific drilling runs in the drilling operation.

[0023] In the illustrated embodiment the computing device 100 is configured to cause the display of a visual indication of a plurality of operating ranges for each of the drilling parameters and to update the display as the drilling operation progresses. As will be further detailed bellow, the computing device 100 can cause the display of an operation set point or target for a particular drilling parameter, a preferred operating range, less preferred operating range, and a least preferred or critical operating range. Because the computing device 100 can cause the display of a visual indication of the ranges of operating parameters, a user can observe the effect of adjusting one drilling parameter on another drilling parameter during the course of the drilling operation.

[0024] Referring to FIG. 1, the drilling system I can include a plurality of sensors configured to measure drilling data during a drilling operation. Drilling data can include expected operating parameters, for instance the expected operating parameter for WOB, drill bit rotational speed RPM, and ROP for a given drilling plan. The sensors can be supported by the drill string downhole or positioned at the surface 11. In the illustrated embodiment, the drill string top sub 45 includes one or more sensors for measuring drilling data. For instance, the one or more sensors can be strain gauges 48 that measure the axial load (or hook load), bending load, and torsional load on the top sub 45. The top sub 45 sensors also include a triaxial accelerometer 49 that senses vibration at the top end 4a of the drill string 4.

[0025] Continuing with FIG. 1, the bottomhole assembly 6 can also include one or more sensors that are configured to measure one or more drilling parameters in the borehole. In addition, the bottomhole assembly 6 includes a vibration analysis system 46 configured to determine various vibration parameters based on the information regarding the drilling operation obtained from the sensors in the borehole. The vibration analysis module will be further detailed below. The bottomhole assembly sensors can be in the form of strain gauges, accelerometers and magnetometers. For instance, the bottomhole assembly 6 can include downhole strain gauges 7 that measure the WOB. A system for measuring WOB using downhole strain gauges is described in U.S. Pat. No. 6,547,016, entitled "Apparatus For Measuring Weight And Torque On A Drill Bit Operating In A Well," hereby incorporated by reference herein in its entirety. In addition, the strain gauges 7 can be configured to measure torque on bit ("lOB") and bending on bit ("BOB") as well as WOB. In alternative embodiments, the drill string can include a sub (not numbered) incorporating sensors for measuring WOB, TOB and BOB. Such a sub can be referred to as a "WTB sub." 10026] Further, the bottomhole assembly sensors can also include at least one magnetometer 42. The magnetometer is configured to measure the instantaneous rotational speed of the drill bit 8, using, for example, the techniques in U.S. Pat, No. 7,681,663, entitled "Methods And Systems For Determining Angular Orientation Of A Drill String," hereby incorporated by reference herein in its entirety. The bottomhole assembly sensors can also include accelerometers 44, oriented along the x, y, and z axes (not shown) (typically with +250 g range) that are configured to measure axial and lateral vibration. While accelerometer 44 is shown disposed on the bottomhole assembly 6, it should be appreciated that multiple accelerometers 44 can be installed at various locations along the drill string 4, such that axial and lateral vibration information at various locations along the drill string can be measured.

[0027] As noted above, the bottomhole assembly 6 includes a vibration analysis system 46, The vibration analysis system 46 is configured to receive data from the accelerometers 44 concerning axial, lateral, and torsional vibration of the drill string 4. Based on the data received from the accelerometers, the vibration analysis system 46 can determine the measured amplitude and frequency of axial vibration, and of lateral vibration due to forward and backward whirl, at the location of the accelerometers on the drill string 4. The measured amplitude and frequency of axial and lateral vibration can be referred to as measured vibration information, The measured vibration information can also be transmitted to the surface 11 and processed by the computing device 100. The vibration analysis system 46 can also receive data from the magnetometer 42 concerning the instantaneous rotational speed of the drill string at the magnetometer 42 location.

The vibration analysis system 46 then determines the amplitude and frequency of torsional vibration due to stick-slip, The measured frequency and amplitude of the actual torsional vibration is determined by calculating the difference between and maximum and minimum instantaneous rotational speed of the drill string over a given period of time. Thus, the measured vibration information can also include measured torsional vibration.

100281 The bottomhole assembly sensors can also include at least a first and second pressure sensors 51 and 52 that measure the pressure of the drilling mud flowing through drilling system components in the borehole 2. For instance, the first and second sensors 51 and 52 measure pressure of the drilling mud flowing through the drill string 4 (in a downhole direction), and the pressure of the drilling mud flowing through the annular gap between the borehole wall and the drill string 4 in an uphole direction, respectively. Differential pressure is referred to as the difference in pressure between the drilling mud flowing in the downhole direction and the drilling mud flowing in the up-hole direction. Pressure information can be transmitted to the computing device 100.

[0029] Further, the drilling system I can also include one or more sensors disposed at the surface, for instance on the derrick 9, For instance, the drilling system can include a hook load sensor 30 for determining WOB and an additional sensor 32 for sensing drill string rotational speed of the drill string 4. The hook load sensor 30 measures the hanging weight of the drill string, for example, by measuring the tension in a draw works cable (not numbered) using a strain gauge. The cable is run through three supports and the supports put a known lateral displacement on the cable. The strain gauge measures the amount of lateral strain due to the tension in the cable, which is then used to calculate the axial load and WOB.

[0030] The drilling system I can also include a drilling data acquisition system 12 that is in electronic communication with the computing device 100. The drilling data acquisition system 12 is configured to receive, process and store data that has been obtained from the various downhole and surface sensors described above. Accordingly, various systems and methods for transmitting can be used to transmit data between drill string components and the drilling data acquisition system 12. For instance, in a wired pipe implementation, the data from the bottomhole assembly sensors is transmitted to the top sub 45. The data from the top sub 45 sensors, as well as data from the bottomhole assembly sensors in a wired pipe system, can be transmitted to the drilling data acquisition system 12 and/or computing device 100 using wireless telemetry. One such method for wireless telemetry is disclosed in U.S. application Ser. No. 12/389,950, filed Feb. 20, 2009, entitled "Synchronized Telemetry From A Rotating Element," hereby incorporated by reference in its entirety. In addition, the drilling system 1 can include a mud pulse telemetry system. For instance, a mud pulser 5 can be incorporated into the bottomhole assembly 6. The mud pulse telemetry system encodes data from downhole equipment, such as vibration information from the vibration analysis system 46 and, using the pulser 5, transmits the coded pulses to the surface 11. Further, drilling data can be transmitted to the surface using other means such as acoustic or electromagnetic transmission.

[0031] Referring to FIG. 2A, any suitable computing device 100 maybe configured to host a software application for monitoring, controlling and predictor drilling operation information as described herein. It will be understood that the computing device 100 can include any appropriate device, examples of which include a desktop computing device, a server computing device, or a portable computing device, such as a laptop, tablet or smart phone. In an exemplary configuration illustrated in FIG. 2A, the computing device 100 includes a processing portion 102, a memory portion 104, an inputloutput portion 106, and a user interface (Iii) portion 108. It is emphasized that the block diagram depiction of computing device 100 is exemplary and not intended to imply a specific implementation and/or configuration. The processing portion 102, memory portion 104, input/output portion tOó and user interface portion 108 can be coupled together to allow communications therebetween. As should be appreciated, any of the above components may be distributed across one or more separate devices and/or locations. For instance, any one of the processing portion 102, memory portion 104, input/output portion 106 and user interface portion 108 can be in electronic communication with the drilling data acquisition system 12, which as noted above can be a computing device similar to computing device 100 as described herein. Further, any one of the processing portion 102, memory portion 104, input/output portion 106 and user interface portion 108 can be capable of receiving drill data from the sensors and/or the vibration analysis system 46 disposed on the drill string 4, [0032] In various embodiments, the input/output portion 106 includes a receiver of the computing device tOO, a transmitter of the computing device 100, or an electronic connector for wired connection, or a combination thereof. The input/output portion 106 is capable of receiving and/or providing information pertaining to communication with a network such as, for example, the Internet. As should be appreciated, transmit and receive functionality may also be provided by one or more devices extemal to the computing device 100. For instance, the input/output portion 106 can be in electronic communication with the drilling data acquisition system 12 and/or one or more sensors disposed on the bottomhole assembly 6 downhole.

10033] Depending upon the exact configuration and type of processor, the memory portion 104 can be volatile (such as some types of RAIvI), non-volatile (such as ROM, flash memory, etc.), or a combination thereof The computing device 100 can include additional storage (e.g., removable storage and/or non-removable storage) including, but not limited to, tape, flash memory, smart cards, CD-ROM, digital versatile disks (DVD) or other optical storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, universal serial bus (USB) compatible memory, or any other medium which can be used to store information and which can be accessed by the computing device 100.

The computing device 100 also can contain the user interface portion 108, which can include an input device 110 and/or display 112 (input device 110 and display 112 not shown), that allows a user to communicate with the computing device 100. The user interface 108 can include inputs that provide the ability to control the computing device 100, via, for example, buttons, soft keys, a mouse, voice actuated controls, a touch screen, movement of the computing device 100, visual cues (e.g., moving a hand in front of a camera on the computing device 100), or the like. The user interface 108 can provide outputs, via a graphical user interface, including visual information, such as the visual indication of the plurality of operating ranges for one or more drilling parameters via the display 112. Other outputs can include audio information (e.g., via speaker), mechanically (e.g., via a vibrating mechanism), or a combination thereof In various configurations, the user interface 108 can include a display, a touch screen, a keyboard, a mouse, an accelerometer, a motion detector, a speaker, a microphone, a camera, or any combination thereof The user interface 108 can further include any suitable device for inputting biometric information, such as, for example, fingerprint information, retinal information, voice information, and/or facial characteristic information, for instance, so to require specific biometric information for access the computing device 100.

[0035j Referring to FIG, 2B, an exemplary and suitable communication architecture is shown that can facilitate monitoring a drilling operation of the drilling system I. Such an exemplary architecture can include one or more computing devices 100, 150 and 160 each of which can be in electronic communication with a database 170 and a drilling data acquisition system 12 via common communications network 180. The database 170, though schematically represented separate from the computing device 100 could also be a component of the memory portion 04 of the computing device 100. It should be appreciated that numerous suitable alternative communication architectures are envisioned. Once the drilling control and monitoring application has been installed onto the computing device 100, such as described above, it can transfer information between other computing devices on the common network 180, such as, for example, the Internet. For instance configuration, a user 24 may transmit, or cause the transmission of information via the network 180 regarding one or more drilling -10-parameters to the computing device 150 of a supplier of the bottomhole assembly 6, or alternatively to computing device 160 of another third party 26 (e.g., a drilling system owner) via the network 80. The third party 26 can view, via a display, the plurality of operating ranges for the one or more drilling parameters as described herein.

[0036] The computing device 100 depicted in Fig. 2B may be operated in whole or in party by, for example, a rig operator at the drill site, a drill site owner, drilling company, and/or any manufacturer or supplier of drilling system components, or other service provider, such as a third party providing drill string design services. As should be appreciated, each of the parties set forth above and/or other relevant parties may operate any number of respective computers and may communicate internally and externally using any number of networks including, for example, wide area networks (WAN's) such as the Internet or local area networks (LAN's).

Database 170 may be used, for example, to store data regarding one or more drilling parameters, the plurality of operating ranges from a previous drill run, a current drill run, and data concerning models for the drill string components.

[0037] Referring to FIG. 3, the drilling system I, such as the computing devices host a software application that cause the processor 102 to execute a method 200 to obtain, determine and display the a plurality of operating ranges for the drilling parameters, including at least an optimized operating parameter. In block 210, the software application can obtain drilling information concerning one or more drilling parameters. For instance, the software application can access drilling information from one or more computer readable storage medium having stored therein drilling information, Further, as should be appreciated, the software application can cause the user interface to display on computer display one or more fields for drilling operation information entry. As such, the software application can receive drilling information.

[0038] In block 220, the software application can determine via a processor a first plurality of operating ranges for one or more drilling parameters. The first plurality of operating ranges can be based on a first duration, or moment, of time operating the drill string 4 during the drilling operation. The determination of the first plurality of operating ranges can be based on drilling information obtain in step 210, as well as the actual and measured drilling information obtained during a drilling operation.

10039] The one or more drilling parameters can also include a first, or control set of drilling parameters that are typically controllable by the rig operator. The control set of drilling parameter are used to assist in controlling the drilling operation and can be the drilling parameters that can be optimized, Optimization is discussed below, The control set of drilling parameters include, but are not limited to, rate of penetration (ROP), weight-on-bit (WOB), mud flow rate, drill bit rotational speed and differential pressure. In addition, the drilling parameters can include a second, or process dependent, set of drilling parameters, the values of which are the result of the drilling operation. The process dependent set of drilling parameters can include torque (kft-lb), rotary speed (RPM), motor speed (RPM), mechanical specific energy (ksi), MSE scatter (ksi), slope of the mechanical specific energy (ksi), pressure (ksi), whirl, bit-bounce, and stick-slip. It should be appreciated that any system of units can be used during the display of the drilling parameters. The process dependent drilling parameters are measured or calculated values and are not necessarily optimizable, as noted above. The software application is configured to distinguish between control drilling parameters and process dependent drilling parameters and to display the applicable operating ranges accordingly. For instance, the control set of drilling parameters can include optimal operating ranges as well as a preferred operating range. Each drilling parameter, including the control set and process dependent drilling parameters, can be measured, calculated and/or predicted according to the methods and systems described in U.S. Patent No. 8,453,764, entitled SYSTEM AND METHOD FOR MONITORING AN) CONTROLLfNG UN)ERGROUN) DRILLING (the 764 patent), the entirety of which is herein incorporated by reference. In addition, in an embodiment of the present disclosure, the present disclosure can also include accessing and using data indicative of a pre-defined model of the drill string and desired drilling parameters, for instance as desciThed in the 764 patent.

[0040] Returning to block 220, the software application can define the endpoints for each operating range (see endpoints 460,462... .474 in FIGS, 5A-9B), such that the user interface can generate a display that illustrates the association that one operating range has to another operating range. Details concerning how the endpoints are determined are discussed below.

[0041] The plurality of operating ranges determined in block 220 can include I) at least one preferred operating range for each drilling parameter, and 2) at least one less preferred operating range for each drilling parameter. The preferred operating ranges can have more than one (a plurality) of preferred operating ranges. For instance, the preferred operating range can include an optimized operating range and a normal operating range. The less preferred operating ranges can have more than one (a plurality) of less preferred operating ranges. The less preferred operating range can include at least one of a high operating range, a severe operating range, and a critical operating range. Accordingly, the plurality of operating ranges can be referred to as a first, second, third... etc., operating range. For instance, a first operating range refers to the -12 -optimized operating range, the second operating range refers to the normal operating range, the third operating range refers to the high operating range, the fourth operating range refers to the severe operating range, and the fifth operating range refers to the critical operating range. Each drilling parameter can include one or more of the aforementioned operating ranges. In some instances, certain drilling parameters may include the optimized operating range as further detailed below.

[0042] The optimized operating range 420 (FIG, SA) is the range of operating values for a particular drilling parameter that can yield the highest ROP for a given drilling plan. The drilling plan can account for the desired ROP and expected wear and tear on the drill string components. Further, the determination of the optimized operating range can take into account the desired and actual operating values for several drilling parameters, surface data and downhole data obtained by the sensors during a drilling operation. For instance, the optimized operating range takes into account, ROP, rotary speed, torque, WOB, flow rate, differential pressure, MSE, and lateral, axial and torsional vibration data, as further detailed below, Thus, according to an exemplary embodiment, the optimized operating range can be the range of operating values for a particular drilling parameter that can yield the highest ROP and the lowest wear and tear on the drill string components. The drilling plan can thus include an assessment of drill string component wear and tear. Expected wear arid tear can be based on the expected! the predicted level of vibration encountered during a drilling run and a lost performance analysis of a drill string component at the level of predicted vibration. Vibration data and lost performance analysis, which can indicate wear and tear of drill string components, can be determined according to the systems and methods disclosed in U.S. Patent No, 8,453,764, herein incorporated by reference in its entirety.

[00431 Continuing with FIG. 3, in accordance with the exemplary embodiment in block 220, the software application can determine the endpoints for the optimized operating range.

The endpoint determination can be based upon: 1) data stored in the database 170 or memory portion 104 obtained during an optimization drilling operation (thrther discussed below), 2) data obtained during a previous drill run and stored in database 170 or memory portion 104, or 3) data obtained real-time during a current drill mn that maybe stored in database 170 and/or memory portion 104. After the optimization drilling operation (or during a drill mn), the software application can determine, for instance, and can cause the display of WOB as a ifmnction of rotary speed, flow rate, differential pressure that shows how MSE, and lateral, axial arid torsional vibration data varies at each given drilling parameter set point. See Fig, 4B which shows a -13 -display 350 that include exemplary graphs 352a through 352h for process depending drilling parameters for a drilling operation. It should be appreciated that 1) rotary speed could be displayed as a function of WOB, flow rate and differential pressure, and 2) flow rate could be displayed as a function of rotary speed, WOB and differential pressure, etc. The software application can thus determine the optimized operating range for WOB, rotary speed, flow rate, differential pressure, by taking into account how WOB, rotary speed, flow rate, differential pressure relate to MSE, and lateral, axial and torsional vibration data obtained during a drilling operation. While the determination of the optimized operating range endpoints is discussed below with reference to the optimization drilling operation, it should be appreciated that the software application is configured to cause the display of optimized operation ranges during a drilling run, [0044] In an accordance with the exemplary embodiment for an optimization drilling operation, set point values for drilling parameters, such as rotary speed, WOB. flow rate and differential pressure, can be selected for the optimization drilling operation. The optimization drilling operation is thus one or more drilling optimization runs that are used to obtain information needed to determine the endpoints of the optimized operating range. For instance, the optimized drilling operation can be initiated and rotary speed, WOB, flow rate and differential pressure can be varied, Changes to the drilling operation can be measured to account for the variance of rotary speed, WOB, flow rate and differential pressures. In particular, the optimized drilling operation can proceed according to an optimization matrix. The optimization matrix can define two drilling parameters, for instance WOB and rotary speed, that are varied during an optimized drill run. For instance, drilling set points of rotary speed equal to 60 rpm and WOB equal to 20k lb WOB can be selected, The optimization matrix varies the values for rotary speed and WOB by a given amount, such as plus or minus 5, 10, 20, etc., for each respective drilling parameter, In an exemplary embodiment, the selected rotary speeds could be 50, 60 and 70 rpm and the selected values WOB may be 20k-Ib, 25 k-lb. and 30 k-lb. Other matrices may include rotary speeds of 50, 60 and 70 rpm and the selected values for flow rates could be 525, 550 and 575. It should be appreciated that other methods, such as design of experiment tools, can be used to determine and/or develop the drilling parameter set points for the optimization drilling operation. An optimization drill run is then commenced for each drilling parameter combination defined in the optimization matrix discussed above. Each optimized drill run can proceed at a predetermined duration of time, for instance a period of time that is sufficient to measure and transmit relevant data to the computing device 100, It should be -14 -appreciated that data acquisition times can vary based on the particular sensors and control systems used in the drilling system and the type of data that is being obtained. For example, when only vibration data is being sent to the computing device for optimized operating range determination, each optimized drilling run will proceed for at least the length of time it takes for the sensors in the drill string to measure and transmit the vibration data to the drilling data acquisition system 12 and/or computing device 100. Each optimized drilling run will then proceed for at least that specific duration of time. If other data is transmitted with the vibration data, the optimized drill run can be proceed for a longer duration. Data from each optimized drilling run can be stored in database 170 or memory portion 104.

[0045] The software application can determine endpoints based on the maximum value for ROP that yields the lowest expected wear on drill string components, taking into account the vibration data obtained during the drilling optimization operation, using the systems and methods disclosed in U.S. Patent No. 8,453,764 noted above. In addition, the software application can also allow the user to input information for endpoint optimization determination, For instance, the user can limit the specific data used to conduct the optimization analysis. The graphical user interface is configured to cause the display of log plots for the data obtained measured over time.

The user can then select a range of time over the optimization drilling operation that is used to perform the optimization analysis. It should be appreciated that other methods can be used to determine the optimal operation range for drilling parameter so long as the optimal operation takes into account drilling information that includes vibration information and expected drill string component useful life, In other words, the optimal operation ranges can be calculated as discussed above, or can be based on information concerning the drilling string components and predicted vibration information.

[0046] The normal operating range 430 (FIG. SA) and optimized operating range 420 can overlap. For instance, the optimized operating range 420 can fall within a portion of the preferred or normal operating range 430. The high operating range 440(FIG. SA) is defined as when the drilling parameter is operating a high level. The severe operating range 451 (FIG. SA) is a severe operation level, The critical operating range 450 (FIG. 5A) is defined as an operating range that will lead to catastrophic damage or system failure should the operation continue at that specific range.

10047] Due the complex nature of the drilling environment, such as pressure, axial, lateral and torsional vibrations of drill string, earthen formation characteristics, and the drill string design and characteristics, the relationship between desired drilling performance and the

-IS -

values for a specific drilling parameter may not be linear for each drilling parameter. In other words, there cai be normal, high, severe, and critical operating ranges for each drilling parameter that are independent of a linear increase in the scale of a given drilling parameter. It has been found that certain drilling parameters may have normal and optimized operating ranges that are bounded, or fall between, less preferred operating ranges (see for instance FIGS. SA and SB).

Each drilling parameter can thus have, and can be displayed as having, more than one (for instance a plurality) of normal operating ranges, more than one (for instance a plurality) of high operating ranges, more than one (for instance a plurality) of severe operating ranges, and more than one (for instance a plurality) of critical operating ranges. The computing device 100 running the software application can determine the plurality of operating ranges for each drilling parameter as noted above in block 220, the extent and the number of specific operating ranges for each drilling parameter, and display those ranges along the scale of the drilling parameter.

The user can then visualize the complex relationship between the various drilling parameters, as the drilling parameters are measured during a drilling operation. The operating ranges can be updated as drilling conditions change or the drilling operation transitions from one drill run to the another drill run.

[0048] Referring again to FIG. 3, in block 230, the software application can cause the user interface to display a visual indication of the first plurality of operating ranges for the one or more drilling operation parameters, for instance on a display screen of the computing device 100.

In block 230, the software application can cause the processor 102 to initiate instructions to the user interface to display the visual indication of the plurality of operating ranges in response to the step of determining the first plurality of operating ranges in block 230. In block 230, the software application can also cause the user interface to arrange each preferred operating range relative to each of the less preferred operating ranges so as to visually indicate whether a preferred operating range is disposed between two less preferred operating ranges, for instance as shown in FIGS. 5A and SB. Further, the visual indication of the operating ranges can be in different colors (FIGS. SA-9B). For instance, the optimized operating range can be represented in blue (see band 420 in FIGS. SA-9B) and the normal operating range can be represented in green (see band 430 in FIGS. SA-9B). The high operating range can be represented in yellow (see band 440 in FIGS. SA-9B) and the severe operating range can be represented in orange (see band 451 in FIGS. SA-9B). The critical operating range can be represented in red (see band 450 in FIGS, SA-9B). It should be appreciated that any color or visual cue can be used to denote different operation information, Further, the drawings are illustrated using the standard -16-representation for different colors according to U.S. Patent and Trademark Office regulations, while the description herein refers to specific colors for clarity of description [0049] In block 240, the software application can receive data indicative of the actual operating value of the drilling parameter. For instance, as noted above, one or more of the sensors can obtain data that is indicative of the operating values of drill string components during the drilling operation. While in some instances sensors may measure a physical response of the drill string to the drilling operation, e.g., instantaneous rotational speed, processors disposed in bottomhole assembly can calculate the drilling parameter for the measured physical response.

The actual operating value for drilling parameter can be transmitted to the computing device 100 at the surface 11 and stored in the memory portion 104 of the computing device 100 for access by the software application. Alternatively or in addition, the physical response data can be transmitted to the computing device 100 at the surface and the actual operating value for the desired drilling parameter can be calculated at the surface, Further, the software application can receive the physical response of the drill string and calculate the actual operating value for the drilling parameter. Data indicative of the actual operating parameter can be transmitted to the surface computing devices via the communications systems discussed above.

[0050] In block 250, in response to receiving data indicative of the actual operating value for the drilling operation, or drill run, the software application can cause the display of the actual operating value for each of drilling parameters relative to the first plurality of operating ranges. The software application may access or receive actual operating data, via the communications system discussed above, prior to the display of such data, The methods described here can also cause the actual operation value of each drilling parameter to be continuously updated as the drilling operation continues, [0051] In block 260, the method can include a step of determining, via the computer processor, a second, updated plurality of operating ranges for the one or more drilling parameters. As further detailed below, the second, updated plurality of operating ranges may be based on a second moment or duration of time operating the drill string. The second, updated plurality of operating ranges include at least the preferred operating range for each of the one or more drilling parameters and the less preferred operating range for each of the one or more drilling parameters.

[0052] In block 270, the software application can cause the user interface to display the second, updated plurality of operating ranges for the one or more drilling parameters, The user -17-interface can display the second, updated plurality of operating ranges in response to the step of determining the second, updated plurality of operating ranges in block 260.

[0053j It should be appreciated that the steps illustrated in blocks 210-260 can be repeated any number of times during a drilling operation. For instance, the method can include the step of determining a third, updated plurality of operating ranges for the one or more drilling parameters. The third, updated plurality of operating ranges can be based on a third duration of time operating the drill string that is subsequent to the first and second durations of time, In response to the step of determining the third, updated plurality of operating ranges, the software application can display, via the user interface, the third, updated plurality of operating ranges for the one or more drilling operation parameters. Further, the method can be run continuously for a single drill run in a drilling operation, or for multiple drilling runs during a drilling operation. In addition, it should be appreciated that the determination of the third plurality of operating ranges, and the associated optimized range for the drilling parameters can be associated with a respective first and second operating ranges for the drilling operation.

The computing device 100, and in particular the graphical user interface, can cause one or more authentication displays (not shown) to be presented to the user. Upon successful authentication, for instance, entry of appropriate user identifiers and passwords, the user interface can generate display 300 as shown FIG. 4A. The display 300 includes a plurality of drilling system component data entry arrays. Each array includes a plurality of data entry fields associated with that respective drilling system component. For instance, the display 300 includes drill bit or bit array 302 that includes data entry fields 320 for maximum WOB, and max/mm drilling mud flow rates, Motor array 304 includes drilling parameters associated with the motor operation, for instance operation of the motor that rotates the drilling sting. Motor array 304 can include, for instance, revolutions per volume of mud, rotor to stator ratio, max/mm. flow rates, WOB, full rated differential pressure, full rated torque, maximum differential pressure, and stall torque. Measure-While-Drilling (MWD) tool array 306 can include data entry fields 326 for drilling parameters associated with the vJIWD tool, for instance, max/mm, allowable flow rates, The display 300 can also include a rotary steerable system (RSS) array 310. As should be appreciated, the RSS array is used when the drilling string includes a rotary steerable system for directional drilling. The RSS array includes data fields 328 for drilling parameters associated with the RSS tool. The display can include additional array 308, denoted as "other" in the illustrated embodiment, that include data entry fields 322 for other components that might be used in a drilling operation. Further, a hole cleaning array 312 -18-can include a data entry field 324 for the minimum flow rate. It should be appreciated that the display 300 can be arranged in other configurations and could include other drilling component arrays as needed.

[0055] Further, the display 300 includes features that allow prior drilling operation information to be automatically populated into the data entry fields. For instance, the display 300 can include a "Bit Run" field 318 that can include a listing of each particular drill mn or bit run performed a drilling operation. If a user selects a previous bit run, by selecting "Bit Run #1", for example, the software application causes the user interface to populate the various data entry fields with drilling data from the selected bit run, The user can input "cancel" at field 316 and the data fields will be depopulated. Alternatively, the user can enter drilling information and create a new "bit mn".

[00561 The user can input the various desired parameters for each drilling parameter in the data fields for each drilling component array 302, 304, 306, 308, 310 and 312. For instance, as shown in FIG. 4A, the user can input values for each drilling parameter that the user would like to optimize or have displayed, Alternatively, the data fields can be populated automatically as noted above. If the user does not want to see operating ranges for a particular drilling system component, then the user can enter "zero" or "n'a" in each data field for the specific drilling component array, Next, the user would click on "select" field 3 14. The software application, based on the inputs and additional drilling information described above would determine the specific operating ranges for each drilling parameter. When the optimization calculations are complete, the software application cause the user interface to generate a display 400 that include digital dials showing, for instance in different colors, the operating ranges for each selected drilling parameter, For instance, the display 400 shown in FIG, 4C include digital dials for each drilling parameter, whereas the display 400 shown in FIG. 4D include digital dials for only a few drilling parameters, as will be further detailed below, As the drilling operation continues, the software application can also illustrate the actual operating for the drilling parameter. Over some period of time, the one or more operating ranges can be automatically updated based on drilling information obtained using surface or downhole sensors, [0057] Turning to FIG. 4B, the computing device 100, via the software application, causes the user interface to display the display 350 graph showing drilling information for a range of drilling parameter values. As discussed above, the display 350 can be based on a drilling optimization operation or an actual or real-time drilling operation, The display 350 can include visual indication, for instance, graphs 352a through 352h, of values for process -19-dependent drilling parameters as a function of WOB, rotary speed, bit speed, flow rate and/or differential pressure (not shown). Accordingly, the display 350 can include measured values for process depending parameters displayed in MSE graph 352a, MSE Scatter graph 352b, ROP graph 352c, axial vibration graph 352d, torsional vibration (stick -slip) graph 352h, lateral vibration graph 352g, MSE flow rate graph 352e, MSE of the drilling motor or rotary speed graph 35211 As should be appreciated, the axes of each graph 352a through 352h can be modified as needed. For example, as discussed above, bit speed can be displayed as a function of WOB if needed. The display 350 also includes calculated normal, optimal, high, severe and critical values 356a through 356h for each respective process dependent drilling parameter. In addition, the display can include the normal, optimal, high, severe and critical operating ranges 354a through 354g for each for each respective process dependent drilling parameter. The user interface can also include a selection icon for causing the optimal drilling parameter set points shown in display 350 to populate digital dials 410 shown in FIG, 4C and discussed below. Thus, the optimal set points and optimal operating ranges can be overlaid upon the normal, high, severe and critical operating ranges and displayed to the drill rig operator Turning to FIG. 4C, the computing device 100, via the software application, causes the user interface to display the visual indication of a first plurality of operating ranges for the one or more drilling operating parameters on a display 400 of an output device, such as display screen. The display 400 can include a plurality of digital dials that graphically represent 1) the various operating ranges for one or more drilling parameters, 2) the actual operating value of each drilling parameter, and 3) alternatively an operational set point for each drilling parameter.

[0059] The display 400 can include a digital dial for each drilling parameter. For instance, the display 400 includes a dial 410 that visually depicts the operating information for the weight on bit (WOB) (k-lb) of a drilling operation. While the display 400 illustrated in FIG. 4C has been configured to show fifteen (15) total drilling parameters, for ease of description, the dial 410 illustrating the WOB is discussed below. It should be appreciated that each dial illustrated includes similar visual representations of specific drilling parameters. The dial 4 0 includes a curvilinear data band 412 and an actual operating parameter indicator 414, for instance an arrow, which points to the actual measured value for the WOB (illustrated at the 22 k-lb hash mark). Each respective dial has a predefined scale that is specific to the particular drilling parameter. The data band 412 can include end portions 416 and 418 as shown. In an alternate embodiment, the data band 42 can be a circular data band. Further, while a curvilinear -20 -data band 412 is shown, the dial 410 can be configured to display a linear data band for each of the parameter.

[0060] The data band 42 includes the visual indication of the operating information for drilling parameters. In the illustrated embodiment in Figs. 4C and 5A, the visual indication of the operating information for WOB includes a plurality of operating ranges for WOB represented in different colors, as discussed above. The optimized operating range 420 can be represented in blue, the normal operating range 430 can be represented in green, the high operating range 440 can be represented in yellow, and a severe operating range 451 can be represented in orange, and the critical operation range 450 can be represent in red. The software application causes the user interface to display the operating ranges along each respective dial data band 412 according to the respective color associated with each operating range. For instance, upon selecting the desired drilling operating inputs in display 300 discussed above, the display 400, the software application, causes the user interface to display the operating ranges along each respective dial data band 412 associated with its respective color.

[0061] Continuing with FIG. 4C, in accordance with the illustrated embodiment, the display 400 includes dials 410, 510, 610, 710 and 810 for each set of controlled drilling parameters, as well as dials 902, 904,. . .918, 920 for each process dependent drilling parameter.

As illustrated, display 400 includes the dial 510 depicting WOB, as discussed above, Dial 510 visually depicts the operating information for the rate of penetration (ROP) (ft/hr) of a drilling operation. Dial 610 visually depicts the operating information for the flow rate of mud flowing through the passage in the drill string during a drilling operation. Dial 710 visually depicts the operating information for the rotational speed (RPM) of the drill bit, Dial 810 visually depicts the operating information for differential pressure (PSI) of a drilling operation. The differential pressure is the difference in pressure between drilling mud passing through drill string 4 in a downhole direction and the pressure of drilling mud passing through the annular passage between the drilling string and borehole wall traveling in an up-hole direction.

[0062] As noted the above, the display 400 can also include dials for each process dependent drilling parameter. Dial 902 visually depicts the operating information for the torque (kft-lb) applied to drill string 4 in a drilling operation. Dial 904 visually depicts the operating information for the rotary rotational speed (RIVIP). Dial 906 visually depicts the operating information for the motor speed (RIVIIP) of a drilling operation. Motor speed in this instance is a measured value that can fall within particular operating range (preferred or less preferred for example) and is process dependent. Dial 908 visually depicts the operating information for the -21 -mechanical specific energy (ksi) of a drilling operation. Dial 910 visually depicts the operating information for the measure of scatter or variability of mechanical specific energy (ksi) during a drilling operation. Dial 912 visually depicts the operating information for the slope of the mechanical specific energy (ksi) of a drilling operation. Dial 914 visually depicts the operating information for the standpipe pressure (ksi) Dials 916, 918 and 920 visually depict various parameters associated with drill string vibration. For instance, dial 916 visually depicts the operating information for the whirl of the drill string during a drilling operation. Whirl in this instance is associated with lateral vibration of the drill sting 4 and can be determined via the vibration analysis system 46 as described above. Dial 918 visually depicts the operating information for the measured bit bounce of the drill bit of drilling operation. Bit-bounce in this instance is associated with axial vibration of the drill sting 4 and can be determined via the vibration analysis system 46 as described above. Dial 920 visually depicts the operating information for stick-slip behavior of the drill string 4 for a drilling operation. Stick-Slip in this instance is associated with torsional vibration of the drill sting 4 and can be determined via the vibration analysis system 46 as described above.

100631 Turning to FIG. 4D, a user 24, via the user interface 108, can modify the display 400 to limit the number of dials shown depicting the drilling operation information. For instance, the display 400 illustrated in FIG. 4C has been configured to show fifteen (15) drilling parameters that include both the controlled and process dependent drilling parameters. The display 400 illustrated in FIG. 4D has been configured to show dials for six (6) drilling parameters, which include dial 510 for ROP, dial 410 for WOB, dial 610 for flow rate, dial 906 for motor rpm, dial 710 for drill bit rotational speed, and dial 810 for differential pressure. It should be appreciated that the user 24, via a user interface, can select any number of dials for depiction on the display 400, using the data entry steps discussed above with respect to the display 300. Thus, the display 400 provides real-time visualization of various operating ranges for each drilling parameter. The displayed operating range is based on actual operating conditions and/or information stored in a database 170 or memory portion 104 regarding the specifics of the bottomhole assembly 6.

100641 The difference between operating in the optimized range 420 and the normal operating range 430 is dependent on the drilling operation arid the pre-defined drilling plan.

When a drilling parameter is operating in the optimized range 420, one or more additional parameters may fall within a normal operating range 430, for instance, bit whirl is minimized and MSE scatter is low, indicating that the drill string is operating consistent with a pre-defined -22 -drill piam Operation within high or yellow operating range 440 would indicate that the drilling parameters exceed the normal operation range. For instance, the actual ROP in dial 510 may fall within preferred, or green, operating range 430 and the WOB shown in dial 410 and stick-slip shown in dial 920 are illustrated as operating in the high ranges 440 (yellow in each dial 510 and 920). Yet, the drill bit RPM as shown in dial 710 is operating within the optimal preferred range 420, shown in blue. Operating ROP in the preferred range 430 may be acceptable to the user 24 viewing the display 400, and no specific adjustment in the drilling process controls will be initiated. By providing a visual indication of one or operating ranges for one or more drilling parameters, a user 24 can observe the impact of adjusting drilling parameters on the drilling operation.

100651 As noted above, each drilling parameter can have more than one (for instance a plurality) of operating ranges for each level or operation ranges, e.g. normal, high, severe, and critical, The relationship among each level of operating range may not be linear, For instance, an increase (or decrease) in a value for a drilling parameter does not necessarily mean that the escalation of the operating ranges from normal to critical will be sequential. Referring to FIGS. 4C, SA and SB, the WOB can have a first high operating range 440 and a second high operating range 442. The normal or green operating range 430 for WOB can be adjacent to and bounded by the first high operating range 440 and the second high operating range 442. Any linear increase in the WOB from a value of 0 (adjacent end point 416) to the value of 30 (adjacent endpoint 418) does not necessarily indicate the drilling operation will run at optimal WOB as [0066] The computing device 100 can cause the user interface to display each operating range on the digital dial band 412 to account for multiple operating ranges and their relationship along a particular scale of the drilling parameter. As discussed above, the computing device 100, via processing portion 102, can determine the operating range end points for each specific operating range and cause the user interface to display the respective operating ranges in a respective color along the data band of the dial in the display 400. Range endpoints can be defined as the operating value where two operating ranges are adjacent, for instance at WOB equal to 5 (k-lb) (Fig. SA). The computing device 100, in accordance with the methods described above, displays each operating range and range endpoints (460, 462, 464, . . .470, 472) (endpoints shown in Figs. SA-9B) so as to define the visual indication of each operating range for each drilling parameter.

-23 - [0067] Referring to FIG. 5A, the computing device 100 can cause the user interface to display a dial 410a that includes visual indication of optimized operating range 420 for WOB adjacent to the second high (or less preferred) operating range 442 and adjacent to data band endpoint 418. A second normal (or second preferred) operating range 430 can be adjacent to and between the first and second less high operating ranges 440 and 442. Further, in the illustrated embodiment shown in FIGS. 5A, the computing device 100, via a processing portion 102, determined that the critical operating range 450 for the drilling operation is between WOB equal to zero (0) (or data band end portion 416) and WOB equal to 5 (k-lb) at a first end point 460.

Further, a severe operating range 45 1 is between WOB equal to S (k-lb), or first endpoint 460, and WOB equal to 10 (k-lb), or a second endpoint 462. The first high range 440 extends from endpoint 462 to endpoint 464, the normal operating range 430 extends from endpoint 464 to endpoint 466, and the second high operating range 442 extends from endpoint 466 to the endpoint 468. The optimized range 420 extends from endpoint 468 to data band endpoint portion 418 (or WOB equal to 30).

[0068] Turning now to Figs. 5A through 9B, the computing device 100 is configured to update the displayed operating ranges to account for changes in drilling conditions over time.

As discussed above, the display 400 provides a visual indication of a first plurality of operating ranges for drilling parameters over a first duration of time, for instance one (1) second (s). The display 400 can be updated to provide a visual indication of a second, updated plurality of operating ranges for drilling parameters over a second duration of time, for instance over one (1) second(s). Data can be received by the computing device 100 once every second, although it should be appreciated that data can be received at rates greater than once per second. Upon receipt of the data, the user interface can cause the display of information at least once every one (1) to five (5) seconds. It should be appreciated that the display time data can be faster than one (I) to five (5) seconds. The second duration of time is subsequent to the first duration of time, It should be appreciated the duration of time can be measured in terms of milliseconds, seconds, minutes, or a larger time duration. Further, the display 400 as shown and described herein is a representation of the operating information of a drilling parameter at a discrete or instantaneous moment in time. It should be appreciated that the displays 400 can be dynamic. Thus, while only a first and second duration of time is illustrated described herein, it should be appreciated that multiple, subsequent and continuous updates of the display 400 are possible, in real-time.

For instance, the computing device 100 can be configured to cause the continuous update of the display 400 with the additional, updated plurality of operating ranges for the drilling parameters.

-24 -Thus, when the drilling operation continues, the computing device can cause the optimized operation range to automatically update based on the drilling conditions, [0069] Referring to Figs. 5A and SB, the dial 40a includes a visual indication of the various operating ranges for WOB of the drilling operation at a first moment of time (or over a first duration of time). The dial 410b illustrated in Fig. SB is a visual indication of the various operating ranges for WOB of the drilling operation at second moment of time (or over a second duration of time). The operating ranges for the WOB in dial 410b have been updated based on the actual and/or measured processing conditions of the drilling operation as described above.

For instance, based on the drilling operation and data concerning the drilling operating, the optimized operating range has been updated. The computing device 100 has shifted the extent of the optimal preferred operating range 420 from between 27 Ic-lb -30 Ic-lb to between 25 k-lb -k-lb. The computing device 100 has caused the display of an updated second high operating range 442. The normal range 430 is adjacent to the first and second less high operating ranges 440 and 442.

[0070] Referring to Fig. oA, the dial 51 Oa includes a visual indication of the various operating ranges for ROP of the drilling operation at a first moment of time (or over a first duration of time). The dial SlOb illustrated in Fig. 6B, is a visual indication of the various operating ranges for ROP of the drilling operation at a second moment of time (or over a second duration of time).
