Abstract
A method comprises: injecting a composition 575 into a settling pool, ideally located within a possum belly 525, of a drilling fluid system and detecting the composition with a gas detector 565. A valve 585 may be opened/triggered to release the composition from a container 580 into the settling pool via an injection tube 545. Alternatively, the settling pool may be within a distribution box or flowline trap. Detecting the composition ideally comprises extracting a gas sample from the drilling fluid with an extractor 560 above the settling pool, a shale shaker 530 or mud ditch 535. A method of injecting and detecting a gas composition in a drilling fluid system is also claimed whereby the system includes a drill string 505 in a wellbore 510 to define an annulus 520, and wherein a suction tube (610, figure 6) passes through an orifice in a wall of a tubular to extend into the drilling fluid system. A sampling end (630, figure 6) of the tube can be used to extract the composition for detection by a gas detector (640, figure 6). An injection tube (645, figure 6) within the suction tube can be used to inject the composition.
Description
METHODS, APPARATUS, AND SYSTEMS FOR INJECTING AND DETECTING
COMPOSITIONS IN DRILLING FLUID SYSTEMS
BACKGROUND
[0001] Drilling fluids are often circulated downhole during drilling operations and perform a number of functions, such as lubricating the area being drilled and removing cuttings that are created during drilling. Once the drilling fluids are returned to the surface, the cuttings can be removed and the drilling fluids can be sent back downhole for reuse. Properties of the drilling fluid are typically monitored during drilling operations. For example, it is often desirable to accurately measure gas concentrations in the drilling fluid, such as hydrocarbon gas concentrations, as the drilling fluid leaves the wellbore. The concentration of various gases in the drilling fluid, such as the concentrations of various types of hydrocarbon gas, can provide a valuable warning system when the concentration of certain gases reach unsafe levels, thereby increasing the safety of the drilling rig and safety of the personnel involved in the drilling operation. Further, the concentration of various types of gases in the drilling fluid can be indicative of the characteristics of the formation being drilled and the drilling environment, and can provide information that can affect how the drilling operation is performed.
[0002] However, various problems with the drilling fluid system can decrease or completely eliminate the ability to accurately detect various gases and their concentrations. For example, a faulty detector or analyzer, or leaks caused by bad seals or faulty connections that allow atmospheric air into the system, can prevent or reduce the ability to accurately detect various gases or measure their concentration.

[0036] In various embodiments, the method, apparatus, or system of the present invention provides certain advantages over current technology, at least some of which are unexpected. For example, in various embodiments, the present invention can determine whether and to what degree there is system integrity between the location of injection of the composition and the location of detection of the composition. For example, in various embodiments, by injecting a composition in one location of a drilling fluid system and detecting the composition in another location, communication between the location of injection and the location of detection in the drilling fluid system can be proven, such as gas communication, liquid communication, or both. In some embodiments, the invention provides a method, system, or apparatus for proving communication between the injection location and the detection location.

Method of injecting and detecting a composition in a drilling fluid system.
[0039] In various embodiments, the present invention provides a method of injecting and detecting a composition in a drilling fluid system. The method can be any suitable method that can be carried out by an embodiment of the system for injecting and detecting a composition or an embodiment of the apparatus for injecting and detecting a composition described herein.
[0040] FIG. I illustrates an embodiment of the method of injecting and detecting a composition in a drilling fluid system. The method 10 of injecting and detecting the composition can include injecting I I the composition into the drilling fluid system. The drilling fluid system can include a gas detector. The method can also include detecting 12 the composition with the gas detector.
[0041] The method can include injecting the composition into the drilling fluid system.
The injecting can be any suitable injecting, such that the composition moves from outside the drilling fluid system to within the drilling fluid system. The injecting can include triggering a valve (e.g., manually opening or electronically opening) to release the composition from a storage container into the drilling fluid system.
[0042] The injected composition can be a liquid composition, a gas composition, or a combination thereof. In some embodiments, the composition can be any suitable one or more gaseous components. The liquid composition can include any suitable liquid, such a liquid substituted or unsubstituted (C2-05o)hydrocarbon, an organic compound, a solvent, water, or a combination thereof. The gas composition can include one or more gaseous substituted or unsubstituted (C2-C30)hydrocarbons. The gas composition can be a gas at the time of injecting. The gas composition can be a gas outside the drilling fluid system immediately before the injecting and during the injecting, in contrast with a calcium carbide method of placing gas in a system which includes placing solid calcium carbide in the system which later reacts with water to form acetylene gas. In various embodiments, the gas composition can be free of acetylene produced from calcium carbide. After the injection, the one or more components of the gas composition can independently be dissolved in the drilling fluid, be partially dissolved in the drilling fluid, or remain a gas.
[0043] The injecting can include injecting into any suitable entry point into the drilling fluid system, such as via an orifice or via an open section of the drilling fluid system that allows depositing a wand or other injection apparatus into the drilling fluid. In some embodiments, the injecting includes injecting the composition through an injection orifice into the drilling fluid system. The injection orifice can be a suitable orifice for injecting the composition into the drilling fluid system and can be located in any suitable location in the drilling fluid system. The injection orifice is an orifice in a wall of a tubular that encloses at least part of the drilling fluid system. The injecting through the orifice can he directly injecting through the orifice or injecting through a body or tube disposed in the orifice, such as a wand or an injection tube. The injecting can include injecting the composition through an injection tube that extends into the drilling fluid system.
[0044] The injection tube can be a wand that allows convenient placement of the injected composition. The drilling fluid system can include a shale shaker and a settling pool upstream of the shale shaker. The settling pool can allow the momentum of the drilling fluid to be dissipated before the drilling fluid enters the shale shaker, to help avoid the momentum of the drilling fluid carrying the drilling fluid over the shale shaker without allowing it time to filter through the screens in the shale shaker. The injecting of the composition can include injecting the composition through the wand into the settling pool (e.g., under the surface of the drilling fluid). The settling pool can he in a possum belly, a distribution box, a flowline trap, or a combination thereof The detecting of the composition can include extracting a gas sample from the drilling fluid system with a gas extractor, such as a gas extractor that is above the settling pool, above the shale shaker, above a mud ditch downstream of the shale shaker, or a combination thereof.
[0045] The detecting of the composition with the gas detector can be any suitable detecting. In embodiments including injection of a liquid composition, the detecting of the composition can include detecting one or more volatilized components of the liquid composition (e.g., detecting one or more components that have changed from a liquid to a gas). The detecting of one or more gaseous components of the composition can include detecting an increase in signal strength of a gas signature from the drilling fluid system, such as a hydrocarbon signature (e.g., an injected component adds to a hydrocarbon signature). The detecting can include detecting liquid components with the gas detector via detection of a drop in signal strength of a gas signature from the drilling fluid system, such as a hydrocarbon signature (e.g., one or more components of the injected liquid composition can remain unvolatilized and can act as a slug that defers or displaces the hydrocarbon signature). The one of more detected components of a liquid composition, via detection of a volatilized component or detection or a drop in signal strength from a hydrocarbon signature, can include detecting the one or more components in diluted form (e.g., mixed with other gases or liquids in the drilling fluid system). In various embodiments, injection of a liquid composition can have advantages such as more similar pumping and transporting of the liquid composition as the drilling fluid, and less disruption of the drilling fluid circuit as a whole.
[0046] The detecting of an injected gas composition with the gas detector can he any suitable detecting. The detecting of the gas composition can including detecting a single component of the gas composition or multiple components. The detecting of the gas composition can optionally include detecting the concentration or volume of one or more components of the gas composition. The gas composition that is detected can be different than the gas composition that is injected, due to dilution of the gas composition with other gases in the drilling fluid system, due to the addition of other gases to the gas composition within drilling fluid system, and due to reaction of or loss of one or more components of the gas composition before the detecting. The detecting of the gas composition can include detecting the gas composition in diluted form, for example, detecting the gas composition mixed with other gases in the drilling fluid system (e.g., mixed with atmospheric gases, produced gases, or other gases). The total volume of the gas sample that enters the gas detector can be less than 100 volume% of the injected composition, such as about 0.000,001 vol% to about 99 vol% of the composition, or about 0.01 vol% to about 50 vol%, or about 0.000,001 vol% or less, or about 0.000,01 vol%, 0.000,1, 0.001, 0.01,0.1, 1,2, 3, 4, 5,6, 8, 10, 12, 14, 16, 18, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 82, 84, 86, 88, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 99.9, 99.99, 99.999, or about 99.999,9 vol% or more.
[0047] The method can include directing a gas sample from the drilling fluid system to the gas detector. Directing the gas sample to the gas detector can include directing a sample of drilling fluid that includes the gas sample (e.g., as a homogeneous or heterogeneous mixture of fluid and gas, optionally including one or more components of the gas sample in the form of gas partially or fully dissolved in the fluid), which can first be passed through a gas extractor to separate liquid components of the drilling fluid from the gas sample, which can then be passed to the gas detector. The gas detector can be fluidically connected to the gas extractor. Directing the gas sample to the gas detector can include directing a sample of gas from the drilling fluid system directly to the gas detector, such as a sample of gas that is substantially free of liquid. A gas sample substantially free of liquid can be taken from a dry drilling fluid system, or from above the drilling fluid such as over the settling pool, over the shale shaker, or above a mud ditch downstream of the shale shaker.
[0948] The drilling fluid system can include a gas extractor. The gas extractor can separate liquid and gaseous components of the drilling fluid, in order to send a gas sample from the drilling fluid system to the gas detector. The gas detector can be fluidically connected to the gas extractor. In some embodiments, such as in a partially-filled or dry drilling fluid system, the gas extractor can take a sample from the drilling fluid system that is all or mostly gaseous and pass the gaseous sample on to the gas detector with little or no separation of liquid and gaseous components. The location of injection (e.g., the location in the drilling fluid system wherein the composition is injected) and the location of detection (e.g., the location in the drilling fluid system wherein the sample of the drilling fluid system is removed) can be any suitable distance away from one another (e.g., flow distance of drilling fluid through the drilling fluid system between the two locations). For example, the drilling fluid system can include a gas extractor fluidically connected to the drilling fluid system about 0 m (i.e., meters) to about -100,000 m downstream of the injecting, or about 0 m to about 50,000 m, or about 0 m (e.g., the location of injecting can be the location of detection), 0.1 m, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, I, 1.2, 1.4, 1.6, 1.8,2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 7, 8,9, 10, 15, 20, 25, 50, 75, 100, ISO, 200, 250, 500, 750, 1,000, 1,500, 2,000, 2,500, 3,000, 4,000, 5,000, 10,000, 15,000, 20,000, 25,000, 50,000, or about 100,000 m or more downstream of the injecting.
[0049] The drilling fluid system can include an inline extraction body. The inline extraction body can be fluidically connected to a gas extractor. The inline extraction body can be any suitable body with a sampling end disposed in the drilling fluid system that can remove a sample from the drilling fluid system. The inline extraction body can provide a gas sample from the drilling fluid system to the gas extractor. The gas sample provided to the gas extractor by the inline extraction body can be a sample of the drilling fluid that includes the gas sample (e.g., as a homogeneous or heterogeneous mixture, wherein one or more components of the gas sample can be partially or fully dissolved in the liquid), or a fully or mostly gaseous sample from the drilling fluid system (e.g., from a drilling fluid system that is partially or fully dry, or from an inline extraction body positioned above the level of drilling fluid in the system).
[0050] In various embodiments, the inline extraction body includes a suction assembly tube in a suction orifice in a wall of a tubular that at least partially encloses the drilling fluid system (e.g., a pipe). The method can include directing a gas sample from the drilling fluid system through the suction assembly tube to a gas extractor fluidically connected to the gas detector. A sampling end of the suction assembly tube can he disposed within an inner diameter of the tubular. In some embodiments, the injecting of the composition includes injecting the composition into the suction assembly tube, such as directly into the suction assembly tube or via another tube disposed within the suction assembly tube. The composition can be injected into the suction assembly tube such that at least some of the injected composition is swept into the suction assembly tube with drilling fluid from the drilling fluid system that is sucked into the suction assembly tube. Injecting the composition can include injecting the composition through the suction assembly tube in an injection tube that is within the suction assembly tube.
[0051] The inline extraction body can include any suitable number of outlets, such as outlets fluidically connected to the suction asse mbly tube. The method can include directing a first portion of drilling fluid in the drilling fluid system through the suction assembly tube and into a first outlet of the inline extraction body. In some embodiments, the first portion of the fluid can be directed to a separator. The method can include directing a second portion of drilling fluid in the drilling fluid system through the suction assembly tube and into a second outlet of the inline extraction body. In some embodiments, the second portion of the fluid can be directed to a gas extractor. In some embodiments, the second portion of the fluid is directed to an inline tee and subsequently directed to a gas extractor.

In some embodiments, the injection tube can extend into the drilling fluid system from an inner wall of the tubular by a distance that is about the same or greater than the distance that the sampling end of the suction assembly tube extends into the drilling fluid system from the inner wall of the tubular (e.g., the sampling end of the suction assembly tube can be farther from the injection orifice in the tubular wall than the end of the injection tube from which the injected composition emerges).
[0963] In embodiments including an injection tube that is within the suction assembly tube, the sampling end of the suction assembly tube can have any suitable spatial relationship with the end of the injection tube from which the injected composition emerges.

Drilling fluid system.
[0974] FIG. 7 illustrates an exemplary drilling fluid system (e.g., wellbore drilling assembly) 700, according to one or more embodiments. It should be noted that while FIG. 7 generally depicts a land-based drilling assembly, those skilled in the art will readily recognize that the principles described herein are equally applicable to subsea drilling operations that employ floating or sea-based platforms and rigs, without departing from the scope of the disclosure.
[0075] As illustrated, the drilling assembly 700 can include a drilling platform 702 that supports a derrick 704 having a traveling block 706 for raising and lowering a drill string 708. The drill string 708 can include drill pipe and coiled tubing, as generally known to those skilled in the art. A kelly 710 supports the drill string 708 as it is lowered through a rotary table 712. A drill bit 714 is attached to the distal end of the drill string 708 and is driven either by a downhole motor and/or via rotation of the drill string 708 from the well surface. As the bit 714 rotates, it creates a wellbore 716 that penetrates various subterranean formations 718.
[0076] A pump 720 (e.g., a mud pump) circulates drilling fluid 722 through a feed pipe 724 and to the kelly 710, which conveys the drilling fluid 722 downhole through the interior of the drill string 708 and through one or more orifices in the drill bit 714. The drilling fluid 722 is then circulated back to the surface via an annulus 726 defined between the drill string 708 and the walls of the wellbore 716. At the surface, the recirculated or spent drilling fluid 722 exits the annulus 726 and can be conveyed to one or more 11 uid processing unit(s) 728 via an interconnecting flow line 730. After passing through the fluid processing unit(s) 728, a "cleaned" drilling fluid 722 is deposited into a nearby retention pit 732 (e.g., a mud pit). While the fluid processing unit(s) 728 is illustrated as being arranged at the outlet of the wellbore 716 via the annulus 726, those skilled in the art will readily appreciate that the fluid processing unit(s) 728 can he arranged at any other location in the drilling assembly 700 to facilitate its proper function, without departing from the scope of the disclosure.

The mixing hopper 734 can include mixers and related mixing equipment known to those skilled in the art. In other embodiments, however, additives can be added to the drilling fluid 722 at any other location in the drilling assembly 700. In at least one embodiment, for example, there could be more than one retention pit 732, such as multiple retention pits 732 in series. Moreover, the retention pit 732 can be representative of one or more fluid storage facilities and/or units where additives can be stored, reconditioned, and/or regulated until added to the drilling fluid 722.
[0078] The fluid processing unit(s) 728 can include one or more of a shaker (e.g., shale shaker), a centrifuge, a hydrocyclone, a separator (including magnetic and electrical separators), a desilter, a demander, a separator, a filter (e.g., diatomaceous earth filters), a heat exchanger, or any fluid reclamation equipment. The fluid processing unit(s) 728 can further include one or more sensors, gauges, pumps, compressors, and the like used to store, monitor, regulate, and/or recondition the drilling fluid.
[0079] Pump 720 representatively includes any conduits, pipelines, trucks, tubulars, and/or pipes used to fluidically convey the drilling fluid to the subterranean formation; any pumps, compressors, or motors (e.g., topside or downhole) used to drive the drilling fluid into motion; any valves or related joints used to regulate the pressure or flow rate of the drilling fluid; and any sensors (e.g., pressure, temperature, flow rate, and the like), gauges, and/or combinations thereof, and the like [0080] Various downhole components contact the drilling fluid during operation, such as the drill string 708, any floats, drill collars, mud motors, downhole motors, and/or pumps associated with the drill string 708, and any measurement while drilling (MWD)/logging while drilling (LWD) tools and related telemetry equipment, sensors, or distributed sensors associated with the drill string 708. Downhole heat exchangers, valves, and corresponding actuation devices, tool seals, packers, and other wellbore isolation devices or components, and the like, can be associated with the wellbore 716. Drill bit 714 can include roller cone hits, polycrystalline diamond compact (PDC) hits, natural diamond bits, hole openers, reamers, coring bits, and the like.
[0081] Transport or delivery equipment can be used to convey the drilling fluid or additives thereof to the drilling assembly 700 such as, for example, any transport vessels, conduits, pipelines, trucks, tubulars, and/or pipes; any pumps, compressors, or motors used to drive the drilling fluid into motion; any valves or related joints used to regulate the pressure or flow rate of the drilling fluid; and any sensors (e.g., pressure and temperature), gauges, and/or combinations thereof, and the like.
[0082] The terms and expressions that have been employed are used as terms of description and not of limitation, and there is no intention in the use of such terms and expressions of excluding any equivalents of the features shown and described or portions thereof, but it is recognized that various modifications are possible within the scope of the embodiments of the present invention.
