Figure 1 illustrates a drilling operation area for example compring a drill floor 100 comprising various operational equipments. As depicted in Fig. 1, the drill floor 100 comprises various drilling components such as a derrick 102, a pipe handling machine 104, and a plurality of hoisting cylinders 106a, 106b and 106c. The drilling operation area comprises further in the illustrated example a driller's cabin 108 situated external to the drill floor 100. The drill floor 100 may include many other drilling components other than the components shown in Fig. 1 for performing various drilling operations on the drill floor 100 with various equipments.

The driller's cabin 108 may include various control equipments, control system nodes, required control ciruitry and other monitoring systems. The various control equipments in the driller's cabin 108 may have communication with the equipments on the drill floor 100 or wellsite via equipment sensors coupled to each equipment or one or more rig sensors located on the drill floor 100 for monitoring various operations of the equipments 102, 104 and 106a-106c on the drill floor 100.

Although many of the equipments on the drill floor 100 are automated and/or operated remotely (e.g. such as from the driller's cabin 108 or from a control room located away from the equipments), there are still numerous personnel often working on, or adjacent to the drill floor 100 during an oil and gas operation. The personnel are required to be involved for monitoring and controlling various equipments and operations of those equipments on the drill floor 100. However, the risk of injury to the personnel increases when the personnel are in the proximity of equipments rotating and/or moving on the drill floor 100. Therefore, it is the objective of the present disclosure to provide an improved drill floor 100 that provides some safety indications to the personnel who are in the proximity of the equipments and to automatically control the equipments when the personnel are in proximity.

In an example which may be used in conjunction with the present invention, a plurality of operation zones namely operation zone 1, operation zone 2,operation zone 3 and operation zone 4 are defined on the drill floor 100 as illustrated in Fig.l.

The plurality of operation zones defined on the drill floor 100 may be higher depending on the number of equipments and types of operations being performed on the drill floor 100. Alternatively, the plurality of operation zones defined on the drill floor 100 may be less depending on the number of equipments and, types of operations being performed on the drill floor 100.

Each operation zone covers a part of the drill floor 100 as illustrated in Figure 1. In an example, the size and shape of each operation zone can be configurable such that each operation zone covers the equipments present in that operation zone. Therefore, the size and shape of the respective operaton zone may be configurable based on the type of equipment 102, 104 and 106a-106c and the type operations performed on the drill floor 100. At least some of the operation zones comprises a safety zone (not illustrated) in proximity to the equipment.

Figure 2 illustrates an example, wherein at least one of the operation zones comprises multiple sub-zones, wherein one of the multiple sub-zones is the safety zone.For example, the operation zone associated to the derrick 102 on the drill floor 100 comprises three sub-zones namely sub-zone 1, sub-zone 2 and sub-zone 3.

One of the sub-zones i.e., either sub-zone 1 or sub-zone 2 or sub-zone 3 may be defined as a safety zone for the derrick 102. For example, sub -zone 1 which is closer to the derrick 102 can be defined as a safety zone.

Therefore, it should be noted that the drill floor 100 may include plurality of operation zones, where each operation zone covers a part of drill floor 100 as illustrated in Fig. 1. Further operation zone may be divided ito a plurality of sub-zones, as illustrated in Fig. 2.

The operation zones may be equipped with sensors for monitoring the operations of various equipments 102, 104 and 106a-106c. In some examples, each equipment 102, 104, 106a-106c,108 on the drill floor 100 can have equipment sensor(s) which may have wired and/or wireless communication with one or more control nodes or control system nodes in the driller's cabin 108. The equipment sensors may be attached to the equipments 102, 104, 106a-106c and can be configured to transmit one or more signals corresponding to the location of the specific equipment. The signals received from the equipment sensors may be used to monitor and/or control the operation of the equipments 102, 104, 106a-106c.

In some examples, the personnel may be wearing one or more sensors. These sensors may be used to track the location of the personnel wearing the sensor by transmitting the signals corresponding to the location of the sensors to the control nodes possibly located in the driller's cabin 108. The sensors can include, a global positioning system (GPS), radio frequency identification (RFID), a video camera or a motion sensor capable of monitoring the position of the personnel. The sensors may be embedded in clothing of the personnel or coupled to the pair of gloves worn by the personnel.

A control node possibly located the driller's cabin 108 may be adapted to receive and process signals from the sensors to determine positions of personnel and/or equipments. For example, a GPS enabled transmitting sensor may provide geographical location and time information to the control node to determine position or location of the personnel.

The control node determines the position of at least one person in the drilling operation area and determines whether the respective determined position is within any of the defined operation zones. Each person is the associated to the operation zone in which the person is located.

Further, the control node identifies a position of a person in the drilling operation area relative to each equipment 102, 104,106a-106c in the operation zones using the equipment sensors and/or the sensors worn by the personnel. Further, the io control node may be configured to evaluate whether the person is in proximity to the one or more equipments based on the identified position. For example, the control node obtains the position information of the equipment from the equipment sensors and the position information of the person using the sensors worn by the personnel. The control node then evaluates whether the person is within a safety zone in proximity to the one or more equipments based on the position information of the equipment and/or the position information of the person.

If the control node determines that the person is in within the operation zone, then the control node may perform one or more actions for automatically or manually controlling the operations of equipments in the drilling operation area and/or for notifying person(s) present in the operation area and/or for notifying an operator of the equipment. The actions may include, for example, stopping operation of the equipment(s) when the person is within the safety zone, reducing speed of the equipment(s), altering path of the equipment(s), altering movement of the equipment(s) and notifying an operator of the equipment(s).

Figure 3 is an example illustration of a position of a person relative to an equipment on the drill floor 100. As depicted in Fig. 3, the equipment 110 on the drill floor 100 can be defined with zones namely zone 1, zone 2 and zone 3 which are represented as Red, Yellow and Green respectively. For example, the zone 1 shown as Red can be considered as a safety zone for the equipment. If the user enters the zone 1, the control node may provide a safety indication to alert the user about an impending risk or danger and may also notify the user to leave from the safety zone, i.e., zone 1.

In different examples, a bounding box 110a which encloses the person as illustrated in Fig. 3 is provided for tracking the position of the relative to the equipment 110. The bounding boxes 112a-112d may also be provided for enclosing the equipments on the drill floor 100 as illustrated in Fig. 4. These bounding boxes 110a, 112a-112d are provided such that they enclose the outer perimetry of the person or the equipments.

The determination of whether the position of a person is in a safety zone may as discussed above determined by the position of the person within an operation zone relative to the equipment 102, 104,106a-106c of that operation zone. The determination of whether the position of a person is in a safety zone may be determined based on a relative position between the bounding box 110a of the person and the bounding boxes 112a-112d of the equipments. For example, the control node may determine the position of the person by monitoring the movement of the bounding box 110a enclosing the person. Further, the control node may determine the movement of the equipments by monitoring the movement of the bounding boxes which enclose the equipments. Therefore, the control node may determine whether the person is near or within a safety zone by determining a relative position between the bounding box 110a of the person and the bounding boxes 112a-112d of the equipment(s). Thus, the control node may determine movement of the bounding box 110a of the person and the movement of the bounding boxes 112a-112d of the equipment(s) to determine whether the person is near or within a safety zone of the equipment 112.

Figures 4a and 4b illustrate example safety indications provided to the person based on a position of a person relative to an equipment on a drill floor. As depicted in Fig. 4a, the person is moving towards the equipment 112 operating in safety zone 1 (i.e., a safety zone of the equipment 112). The control node may be configured to determine the movement of the bounding box 110a of the person and the movement of the bounding boxes 112b-112d of the equipment 112 to determine whether the person is near or within a safety zone of the equipment 112. When the person is determined to be nearing the safety zone of the equipment 112, the control node may be configured to provide a safety indication to the person by automatically close the barrier 114 as illustrated in Fig. 4a in order to stop the person from entering the safety zone of the equipment 112. The barrier 114 may be a gate, a barricade, a safety boom, an enclosed structure, or the like which may alert or indicate the person about an impending risk of entering the safety zone of the equipment 112.

In an example, the barrier 114 may be activated automatically upon determining that the person is entering the safety zone of the equipment 112. Alternatively, the barrier 114 may be displayed as graphical element or a graphical object such as a safety icon which indicates the person about an impending risk of entering the safety zone of the equipment 112.

In another example, a safety indication to the person about an impending risk of entering the safety zone of the equipment 112 can be provided with a light indicator 116 as illustrated in Fig. 4b. For example, the person is indicated about not to enter the safety zone of the equipment 112 by activating a red light on the light indicator 116 (the light at the top of the indicator). The yellow light (middle light of the indicator) when activated indicates the person to wait for a time interval for completing an ongoing operation by the equipment 112. The green light indication (the light at the bottom of the indicator) allows the person to enter the safety zone of the equipment.

In some examples, an alaram or a buzzer may be activated automatically upon detecting the user entering the safety zone of the equipment 112.

Thus, the person may be indicated about safety by activating the barrier 114, the zo light indicator 116, an alaram or a buzzer, or the like, where these safty indications may be activated automatically. Alternatively, these safety indications may be activated with manual control of the the barrier 114, the light indicator 116, an alaram or a buzzer, or the like. Therefor, the control node enables one or more safety indications to the person on the drill floor through the one or more indications zo as described above.

Figure 5 illustrates a control system node 500 comprising various modules 502-516 for monitoring operations in a drilling operation area such as a drill floor 100, as disclosed in this disclosure. As illustrated in Fig. 5, the control system node 500 includes a communicator 502, a zone classifier 504, a position identifier 506, a position evaluator 508, a storage 510, a drilling controller 512, a processor 514 and a display 516.

The communicator 502 can be configured to receive and process signals from equipment sensors and/or sensors worn by the personnel. The communicator 502 can be adapted to support one or more suitable communication protocols to receive and process signals from the equipment sensors and/or the sensors worn by the personnel.

The zone classifier 504 can be configured to define plurality of operation zones in a drilling operation area, such as operation zone 1, operation zone 2, operation zone 3 and operation zone 4 in the drilling operation area as illustrated in Fig. 1. Further, the zone classifier 504 can be configured to define the plurality of sub-zones for io example sub-zone 1, sub-zone 2 and sub-zone 3 for anequipment in a drilling operation area, as illustrated in Fig. 2. Thus, the zone classifier 504 can be configured to define the plurality of operation zones on the drill floor 100 and/or it can be configured to defines plurality of sub-zones for each equipment, wherein the sub-zones may include the safety zone. In some examples, the zone classifier 504 can be configured to redefine the plurality of operation zones in accordance with a type of operations carried out by the equipment in said operation zone.For example, after the equipment executes a first action (such as rotation of a pipe) in a sequence of tasks in the drilling operation area, the zone classifier 504 can be configured to redefine the plurality of operation zones in accordance with a second task to be executed by the equipment before starting execution of this second task in the sequence of tasks of the equipment. Thus, the zone classifier 504 may be configured to redefine the plurality of operation zones in accordance with the type of operations performed in the drilling operation area.

The position identifier 506 can be configured to identify the position of a person in a drilling operation area. The position identifier 506 can be configured to extract data or information related to the position of the person through one or more sensors installed in the plurality of zones. Further, the position identifier 506 can be configured to calculate a location of the person based on the extracted data from the sensors. Furthermore, the position identifier 506 can be configured to determine whether the person is near or within an operation zone and/or safety zone among the plurality of operation zones using the location of the person. Thus, the position identifier 506 can be configured to determine positions of the person and/or other equipments 102, 104 and 106a-106c using data extracted from the sensors. For example, a GPS enabled transmitting sensor may provide geographical location and time information to the control system node 500 to determine location and/or positions of the person wearing the sensors. The position identifier 506 can be configured to communicate the determined positions of the person and/or other equipments 102, 104,106a-106c to the position evaluator 508.

The position evaluator 508 can be configured to evaluate whether the person is in the safety zone in proximity to the one or more equipments based on the identified position(s) of the equipment sensors and the positions of the sensors worn by the person (i.e.,received from the position identifier 506). The position evaluator 508 can be configured to evaluate whether the person is in the safety zone in proximity to the one or more equipments by comparing the identified position(s) of the equipment sensors and the positions of the sensors worn by the person.

In an example, the position evaluator 508 can be configured to evaluate whether the person is near or within a safety zone among the plurality of zones by determining a relative position between the bounding box 110a provided to the person and the bounding boxes 112a-112d of the one or more equipments.

The storage 510 can be configured to store the position information of the person and the position information of the various equipment sensors. The storage 510 can be configured to store the information related to the sequence of operations of the various equipments on the drill floor 100. Further, the storage 510 can be configured to store various instructions for execution of those instructions by the processor 514.

The drilling controller 512 can be configured to perform one or more actions in response to evaluating that the person in proximity to the one or more equipments 102, 104,106a-106c in the drilling operation area. For example, the drilling controller 512 can be configured to stop the operations of the equipment(s) 102, 104, 106a- 106c when the person is within the safety zone of that equipment 102, 104,106a-106c, reduce speed of the equipment 102, 104, 106a-106c, alter path of the equipment 102, 104,106a-106c, alter movement of the equipment 102, 104, 106a-106c and notifies an operator of that equipment 102, 104, 106a-106c or the like.

In some examples, the drilling controller 512 can be configured to receive the position of the user continuously from the position identifier 506. When it is identified that the person has left the safety zone of a particulat equipment, based on the information received from the position identifier 506, the drilling controller 512 can be configured to automatically re-start the operation of that equipment.

In some embodiments, the drilling controller 512 can be configured to continuously monitor the operations of the equipments 102, 104 and 106a-106c in the operation zones and can be configured to automatically control the operations of the equipments based on the identified position of the person relative to each equipment 102, 104 and 106a-106c in the safety zones.

The display 516 can be configured to display the various ongoing operations of the equipments 102, 104, 106a-106c in the drilling operation area on a display screen for example provided in the driller's cabin 108 for monitoring purpose. The display 516 can be configured to display the positions of the person(s) in the drilling operation area relative to the operation zone and/or safety zone related to the respective equipment 102, 104, 106a-106c. The person(s) in the driller's cabin 108 may monitor the various operations of the equipments 102, 104,106a-106c in the drilling operation area by continuously monitoring the display screen showing the operation of the equipments 102, 104,106a-106c. The display 516 may be provided in the form of a Graphical User Interface (GUI) through which the person(s) in the driller's cabin 18 may remotely monitor and control the various operations of the equipments 102, 104,106a-106c in the drilling operation area.

Figure 6a is a flow chart 600 illustrating a method for controlling drilling operations in a drilling operation area, which may be used in conjunction with the present invention.

The method may comprise a step of obtaining Si a sequence of instructions for execution of operations of the one or more equipments of at least one of the operation zones. In this regard, an instruction corresponds to one or more steps carried out by the equipment to perform an operation.

The method comprises a step of defining S2 a plurality of operation zones in a drilling operation area, each operation zone comprising at least one equipment arranged to operate in the operation zone. At least one of the operation zones may comprises multiple sub-zones, wherein one of the multiple sub-zones is a safety zone. The extension of the plurality of operation zones, and possibly the extension of the sub-zones, are defined in accordance with a type of operations carried out by equipment in the respective operation zone.The operation type may for example be selected from at list comprising at least some of the following operation types.

* picking up tubular * laying down tubular * tripping in hole * tripping out of hole * wet trip * drilling connection * back reamer * running riser * stand building * casing building * laying down tubulars via stand building system The extension of the plurality of operation zones may be adaptively redefined in accordance with the type of operation presently carried out by the equipment in the respective operation zone.

A size and/or a shape of each operation zone may be configurable. For example, the size and/or shape of each operation zone may be manually configurable, for example via a user interface. For example, the size and/or shape of the respective operation zone may be pre-configurable in accordance with the type of operation carried out in that operation zone and the size and/or shape may then be manually refined using the user interface.

The method may then comprise a step of initiating execution S3 of an operation of the respective equipment.

In practice, when a new type of operation is to be performed, an operation zone may be defined corresponding to that operation type, as discussed above, and a sequence of instructions for execution of this new type operation is obtained Then, the equipment is controlled in accordance with the obtained sequence of instructions.

The step of determining one or more actions to be performed may then comprise, instead of or in addition to the actions discussed above, at least one of: altering one or more planned operations of the one or more equipments; and delaying one or more planned operations of the one or more equipments.

In different examples, automatically controlling the operations of the one or more equipments may comprise: executing a first instruction in the sequence of instructions; redefining the plurality of operation zones upon executing the first instruction; and executing a second instruction in the sequence of instructions.

Thus, the operation zones may be updated for each new instruction carried out by the respective equipment.

In different examples the method further comprises a step of identifying whether a person in the operation zone is an authorized person. The one or more actions to be performed is then determined based on the identification of wheter the person in the io operation zone is authorized. For example, a safety indication may be provided to the person if the identified person is not an authorized person.

Figure 6b is a flow chart illustrating an example of a step for determining action(s) to be performed in the method of figure 6a. In figure 6b, the step of determining S10 one or more actions comprises determining 5102 a first type action when a person has been determined to be in the safety zone and determining S101 a second type action when no person has been determined to be in the safety zone. In an example, the second type action is determined based on the number or persons which has been determined to be present within the operation zone. Other examples of the one or more actions are described for example in relation to figure 6a.

Figure 7 is an example illustration of providing a safety indication to a person in the drilling operation area. As illustrated in Fig. 7, the person is moving in the drilling operation area. When the person enters a safety zone (for example zone 1 in the illustrated example) of the equipment 110, the control system node 500 provides a safety indication to the person. The safety indication may include activating an alarm indication to indicate the person to leave from the safety zone of the equipment 110.

In an example, the control system node 500 can be configured to identify whether the person in the safety zone to be an authorized person. If the control system node 500 identifies the person to be the authorized person, then the control system node 500 may not activate the alarm to provide the safety indication, as the person is identified as the authorized person who is required to be present at the safety zone to enable the equipment 110 and/or for monitoring and controlling equipment 110 to perform required operations.

In case the control system node 500 identifies the person not to be the authorized person, then the control system node 500 may activate the alarm to indicate to the person to leave from the safety zone of the equipment 110.

Figure 8 illustrates an example of various steps in performing sequence of instructions in a drilling operation area by redefining the zones. These steps may for example be carried out in the methods as discussed in relation to figure 6a. As depicted in Fig. 8, at step 1, the plurality of operation zones are defined in the drilling io operation area such as zone 1, zone 2, zone 3, and zone 4 as illustrated in Fig. 1.

When carrying out the methods as disclosed in relation to Fig 6a., this corresponds to step 52. At step 2, the automated sequence of instructions are extracted. When carrying out the methods as disclosed in relation to Fig. 6a, this corresponds to step Si. At step 3, a first instruction in the sequence of instructions is executed. When carrying out the methods as disclosed in relation to Fig. 6a, this corresponds to step 53. Upon execution of the first instruction, the plurality of operation zones are redefined. When carrying out the methods as disclosed in relation to Fig. 6a, this corresponds to that the process goes back to execution of step S2. Then, a second instruction in the sequence of instructions is exectuted. When carrying out the methods as disclosed in relation to Fig. 6a, this corresponds to step 53. Further, after exectution of the second instruction, the plurality of zones are redefined again. Therefore, in this example, the plurality of zones are continuously redefined upon execution of the instructions among the pre-defined sequence of instructions. In this regard, an instruction corresponds to one or more steps carried out by the equipment to perform an operation.

Figure 9 is a flow chart illustrating various steps in accordance with an example of a step of determining S9 whether the position of a person is in a safety zone. The step S9 of determining whether the position is in a safety zone may be performed in the methods 600 as discussed in relation to Fig. 6a. The step 59 of determining whether the position is in a safety zone comprises in the illustrated example of Fig 9 obtaining 591 a bounding box 110a enclosing the person; obtaining 592 one or more bounding boxes 112a-112d enclosing one or more equipments 102, 104, 106a-106c in each operation zone; and determining S93 whether the person is proximate the equipment based on a relative position between the bounding box 110a of the person and the bounding boxes 112a-112d of the one or more equipments 102, 104, 106a-106c.

Movement of the one or more bounding boxes 112a-112d enclosing the equipment(s) and/or the the bounding box 110a enclosing the person is identified and the determination S93 wheter the person is proximate the equipment is updated when a movement has been identified.

As illustrated in Fig.11a, the equipments A, B and C are illustrated in bounding boxes 112a, 112b and 112c respectively. The equipments A and B are moving towards equipment C. In this embodiment, a control system node 500 may be configured to identify the movement of the bounding boxes 112a and 112b and thereby identifying the movement of equipments A and B. The control system node 500 may be configured to evaluate whether the movement of the one or more bounding boxes 112a and 112b is in accordance with the required sequence of operations on the drill floor 100. If it is determined that the movement of the one or more bounding boxes 112a and 112b is in accordance with the required sequence of operations on the drill floor 100, then the control system node 500 allows the movement of the equipments A and B towards the equipment C. Thus, the equipments A and B in bounding boxes 112a and 112b are moved towards the equipment C in the bounding box 112c as illustrated in Fig. 11b.

In an example, the movement of the one or more bounding boxes 112a-112c are tracked continuously to determine whether the equipments enclosed in those bounding boxes 112a-112c are moving in accordance with the required sequence of operations on the drill floor 100. In case, any of the equipment A, B C or the like is found to be in motion and is not in accordance with the required sequence of operations, then the control system node 500 may be configured to alter or vary the movement of any of the equipment A, B, C or the like to align that equipment in accordance with the required sequence of operations on the drill floor 100. Thus, the control system node 500 may be configured to automatically control the operations of one or more equipments A, B, C or the like by monitoring the movement of the one or more bounding boxes 112a, 112b and 112c respectively.

Figures 11c and 11d illustrate a variation in size and shape of the bounding boxes in accordance with the type of operations of the equipments. In an embodiment, the size and the shape of each bounding box 112a-112c is configurable based on state of the one or more equipments on the drill floor 100.
