Description

SYSTEMS AND METHODS FOR A TUBULAR MOUNTING AND DISMOUNTING APPARATUS TECHNICAL FIELD

[0001] The invention generally relates to, but is not limited to, an apparatus and associated methods used in well-bore penetration. More specifically, the apparatus is equipped to autonomously assist with mounting and dismounting tubulars on a rig floor or hole center.BACKGROUND

[0002] In well bore drilling, conventional operations typically involve specialized crews and manual equipment that are brought to a rig site for operation. The floor of the rig is particularly dangerous and presents a safety hazard for the rig workers required to be on the rig floor to manually operate equipment for the mounting and dismounting of tubulars from drilled wells.SUMMARY

[0003] It is an advantage of the present invention to provide a tubular mounting and dismounting apparatus which may operate in -40-degree Celsius conditions, utilizes hydraulics to operate, may operate autonomously, and may operate without requiring humans on the rig floor (a.k.a., the red zone).

[0004] In one general aspect, the method may include positioning the tubular mounting and dismounting apparatus about a first tubular in a retracted and closed position with the first tubular and a top coupling of the first tubular extending vertically through a base of the telescoping guide and grabber. The method may also include lowering a second tubular through a guide assembly at the top of the tubular mounting and dismounting apparatus where the top of the second tubular is secured. The method may furthermore include aligning, via a stabbing guide of the tubular mounting and dismounting apparatus, the second tubular with the top coupling. The method may, in addition, include converting the tubular mounting and dismounting apparatus toAmbumLaw Docket No. 6174.015 1an extended and open position and generating a connection between the second tubular and the top coupling. The method may, moreover, include determining that the connection between the second tubular and the coupling falls below a predetermined threshold. The method may also include converting the tubular mounting and dismounting apparatus to a retracted and closed position and securing the top coupling with a top jaw and the first tubular with a first bottom jaw and a second bottom jaw. The method may furthermore include releasing the connection between the second tubular and the top coupling and releasing the top jaw, the first bottom jaw, and the second bottom jaw. The method may, in addition, include repositioning and securing the top jaw to the second tubular, the first bottom jaw to the top coupling, and the second bottom jaw to the first tubular. The method may moreover include freeing the second tubular from the CRT. The method may also include releasing the top jaw and lifting the second tubular out from the top of the tubular mounting and dismounting apparatus.

[0005] In another aspect, a tubular installation apparatus is adapted to enable positioning and joining of tubulars over a hole center on a rig table directly above a well bore, the apparatus not including the tubulars, the apparatus includes a frame having a top and bottom portions, and a first and second side portions, wherein the bottom portion comprises a first set of jaws adapted to hold and position a first tubular in a down hole position with the first set of jaws in a closed position around the first tubular, wherein the top portion comprises a second set of jaws adapted to open and close to hold and position a second tubular in alignment with the first tubular, wherein the second set of jaws are adapted to open and close independently of the first set of jaws, wherein at least the first set of jaws include a first jaw portion disposed within the first side portion and a second jaw portion disposed within the second side portion, wherein the frame allows forAmbumLaw Docket No. 6174.015 2cooperatively opening and closing the first set of jaws and the second set of jaws to hold, position, and join the first tubular to the second tubular.

[0006] Other embodiments of this aspect include corresponding computer systems, apparatus, and computer programs recorded on one or more computer storage devices, each configured to perform the actions of the methods.BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The systems and methods described herein were designed for the installation and removal of tubulars of well center applications (e.g., oil, gas, water, hydrogen, helium, and any material which may be transferred via drilling or trenched), for use with autonomous installation of tubulars which frees humans from being present or assisting on the well center. The drilling rig floor (a.k.a., the red zone) is highly dangerous for human operators, and they are at a significant risk of injury when present. In some embodiments, a well center may be a well bore, a rig floor, a trench, or any place tubulars may be installed.

[0032] The systems and methods described herein may overcome multiple problems associated with installment of tubulars with the use of, but not limited to, an automated casing running tool (CRT) (e.g., DRAWWORKS, VOLANT, and the like), a hydraulically controlledAmbumLaw Docket No. 6174.015 6device may be paired with flush mount slip (FMS), and positioning of tubulars over hole center within rig table directly above the well bore.

[0033] The systems and methods described herein are configured to negate the need for workers to apply different tools during tubular installment operations. In some embodiments, tubular installment operations may comprise stabbing guidance, hose filling, pipe grabbing, thread steaming, blowing, temperature sensing, visual thread scanning utilizing artificial intelligence, and applying doping.

[0034] The systems and methods described herein may be configured to tether the tubular when presented to the top section, then hold the tubular in place as it is positioned into the stabbing guide assembly in a downward motion. The systems and methods described herein may be configured to align the tubular as it comes in line with the hole center while being added to the next tubular in the well bore, which may protect the threads of the tubular with the application of polytetrafluoroethylene (e.g., TEFLON) at areas likely to cause wear or damage (e.g., tubular catch assembly, stabbing guide assembly, and any component which comes into contact with the tubular).

[0035] The systems and methods described herein may be configured to secure the bottom section of the tubular when positioned into the FMS or rigs table while being secured to the coupling of the next tubular, and when backing out a connection by holding torque, and to reduce loss of connecting between the tubular and the coupling.

[0036] The systems and methods described herein may be configured to accommodate tubulars of as many sizes as possible. In some embodiments, the systems and methods described herein may be configured to operate with tubulars sizes comprising but not limited to 23 / 8 through 14 inches. The systems and methods described herein may be configured to utilize modularAmbumLaw Docket No. 6174.015 7components which may be removed quickly and independently to accommodate different sized tubulars. The systems and methods described herein may be configured to operate in rain and snow, from -40 C to +40 C temperatures, and may be exposed to drilling fluids and gasses.

[0037] The systems and methods described herein may be configured to utilize the tubular mounting and dismounting apparatus comprising components made from 44W-50W steel utilized for its availability and workability. The 44W-50W steel may have suitable characteristics for the expected loads and environmental conditions. In some embodiments, components may be comprised of aluminum, carbon, titanium, plastic, or some composite thereof. The tubular mounting and dismounting apparatus may further comprise components made from or coated with polytetrafluoroethylene which may aid in impact absorption and reduce scratches, depressions and dents on the tubulars and the threads of the tubulars. The tubular mounting and dismounting apparatus may further comprise components made from 44W-50W steel as well as 1026 steel. The tubular mounting and dismounting apparatus may further comprise components made from plastic (e.g., tubular guides), which may reduce wear and friction against metal and may reduce damaging the threads of tubulars.

[0038] The tubular mounting and dismounting apparatus may be configured to come apart into halves; this is advantageous because the equipment to which the tubular mounting and dismounting apparatus may be mounted may also separate into halves and hinges open for installation. For that reason, the tubular mounting and dismounting apparatus may comprise geometry, which may be used to connect or align components when hinged closed. The tubular mounting and dismounting apparatus may be configured to adjust in height to accommodate variances in stump height.AmbumLaw Docket No. 6174.015 8

[0039] In some embodiments, in order to accommodate multiple size tubulars, the collar jaw of the tubular mounting and dismounting apparatus may be configured to slide the jaws and the T-bone independently (described in greater detail below). The jaws of the tubular mounting and dismounting apparatus may account for the difference in diameter between the tubular and the collar of the tubular, while the T-bone may account for the difference between tubular diameters.

[0040] In some embodiments, a CRT may be any accessory attached to a top drive which transfers a turning motion to a tubular. In some embodiments, a top drive may connect directly to a tubular and act as the CRT.

In some embodiments, the set of adjustable safety stops (107, 110, 113, and 115) may be configured to prevent and contain the tubular from swinging freely around the working floor or hole center. In some embodiments, the set of adjustable safety stops (107, 110, 113, and 115) may be configured to provide a loose hold above the previous tubular segment, where the stabbing guide insert 130 may be positioned above the previously installed tubular. In some embodiments, the tubular catch assembly (105, 107, 110, 113, 115, 125) may be adjusted to fit most tubulars but not limited to (e.g., 2 3 / 8 through 14 inch diameters), including tubulars which may feature geometry designed to assist in guiding tubulars towards the hole center. In some embodiments, the tubular catch assembly (105, 107, 110, 113, 115, 125) may further comprise an adjustable lock 105, which may allow tubulars to enter the tubular mounting and dismounting apparatus 100 but may not leave.

[0045] In some embodiments, the tubular catch assembly (105, 107, 110, 113, 115, 125) may comprise a pair of tubular arrestor plates (125A and 125B) with multiple guides and stops mounted to the stop where some of the guides and stops may comprise or be coated with polytetrafluoroethylene. In some embodiments, the tubular catch assembly (105, 107, 110, 113, 115, 125) may connect to the top of the tubular mounting and dismounting apparatus 100 and may be positioned a distance above the center of the hole which may prevent crashing of the tubular into the other components. In some embodiments, the tubular catch assembly (105, 107, 110, 113, 115, 125) may comprise geometry that may guide a tubular into the center of the tubular arrestorAmbumLaw Docket No. 6174.015 10plate 125, and the set of adjustable safety stops (107, 110, 113, and 115) which may prevent a tubular from leaving the midline of the tubular mounting and dismounting apparatus 100.

[0046] In some embodiments, the tubular catch assembly (105, 107, 110, 113, 115, 125) may comprise 44W-50W steel for its structure and workability. 44W-50W steel has good characteristics for the expected loads and environmental conditions. In some embodiments, the tubular catch assembly (105, 107, 110, 113, 115, 125) may further comprise polytetrafluoroethylene components or coatings, which may aid in impact absorption and reduce scratching tubulars when in use. In some embodiments, components made from aluminum, carbon, titanium, plastic, or some composite thereof may be utilized.

[0047] FIG. 8 illustrates a non-limiting first embodiment of the telescoping arm and hinge assembly, which may comprise a telescopic arms 135, an extension actuator 137, one or more hinge actuators 150, and a mounting plate 155. In some embodiments, the tubular mounting and dismounting apparatus 100 comprises two telescoping arm and hinge assemblies which mirror each other in form and function, as illustrated above.

[0048] In some embodiments, the telescoping arm and hinge assembly (135, 137, 150, 155) may comprise a pair of telescopic arms 135. In some embodiments, the telescoping arm and hinge assembly (135, 137, 150, 155) may be configured to extend and retract to assist with the alignment of different sump heights (i.e., the height of where the operator has set the tubular in slips and the remaining height of the tubular coupling sticking above the slip). In some embodiments, the extending and retracting movement may be controlled by an extension actuator 137. In some embodiments, the telescoping arm and hinge assembly (135, 137, 150, 155) may be configured to hinge open and closed with a tilting motion, which may allow travel of the CRT andAmbumLaw Docket No. 6174.015 11top drive to pass through with the next tubular segment. In some embodiments, the opening and tiling movement may be controlled by one or more hinge actuators 150.

[0049] In some embodiments, the mounting plate 155 may attach to the telescopic arms 135. In some embodiments, the mounting plate 155 may be split to allow for the tubular mounting and dismounting apparatus 100 to be hinged open for removal. In some embodiments, the mounting plate 155 may comprise the mounting points for the telescopic arms 135 that control the opening and closing of the tubular mounting and dismounting apparatus 100.

In some embodiments, the telescopic arms 135 may be attached via a plate that hinges off the mounting plate 155. In some embodiments, a series of ribs may reinforce the outer slide tubes at the zenith of the inner slide’s travel. In some embodiments, the outer slide may comprise a bracket with multiple mounting points which may allow for adjustment of the angle the tubular mounting and dismounting apparatus 100.

[0051] In some embodiments, the inner slide may comprise parallel vertical tubes that may fit within the outer slide. In some embodiments, the inner slide may comprise several tool mounting points with additional safety measures to prevent components from coming undone during operation.AmbumLaw Docket No. 6174.015 12

[0052] In some embodiments, the telescopic arms 135 may comprise 44W-50W steel for its availability and workability. 44W-50W steel has good characteristics for the expected loads and environmental conditions. In some embodiments, components made from aluminum, carbon, titanium, plastic, or some composite thereof may be utilized.

[0053] FIG. 9 illustrates a non-limiting embodiment of the stabbing guide assembly (130, 131, and 133), which may comprise a stabbing guide insert 130, a stabbing guide mount 133, and a locking plate 131. In some embodiments, the tubular mounting and dismounting apparatus 100 comprises two stabbing guide assemblies which mirror each other in form and function, as illustrated above.

[0054] In some embodiments, the stabbing guide insert 130 may be comprised of plastic and may be used to guide the next tubular into place in the installed tubular while protecting the threads from both sides. In some embodiments, the stabbing guide insert 130 may be mounted to the stabbing guide mount 133, which may hold the stabbing guide inserts 130 in varying sizes to accommodate most tubular sizes and may be quickly interchanged for different-sized tubulars.

[0055] In some embodiments, the stabbing guide insert 130 may comprise a pair of semicircular guides with geometry which may allow the stabbing guide insert 130 to align to the collar of the previous tubular and help aim the next segment of the tubular into the center. In some embodiments, the bracket may be quickly removed to access the collar jaw beneath.

[0056] In some embodiments, the stabbing guide mount 133 may comprised of 44W-50W steel and 1026 steel. In some embodiments, components made from aluminum, carbon, titanium, plastic, or some composite thereof may be utilized.

[0057] FIG. 10 illustrates a non-limiting embodiment of the tubular grabbing jaw and T-bone assembly, which may comprise a top jaw 141, a first bottom jaw 142, a second bottom jawAmbumLaw Docket No. 6174.015 13143, a T-bone assembly 146, and a T-bone mount 145. In some embodiments, the tubular mounting and dismounting apparatus 100 comprises two tubular grabbing jaw and T-bone assemblies which mirror each other in form and function, as illustrated above.

[0058] In some embodiments, the tubular grabbing jaw and T-bone assembly (141, 142, 143, 145, 146) may comprise three pairs of jaws, the top jaw 141 may be located just below the stabbing guide assembly (130, 131, and 133). In some embodiments, below the top jaw 141 may be attached to the T-bone assembly 146. In some embodiments, below the top jaw 141 and attached to the T-bone assembly 146 may be the first bottom jaw 142 and the second bottom jaw 143. In some embodiments, the top jaw 141, the first bottom jaw 142, and the second bottom jaw 143 may each comprise a hydraulic cylinder mounted to a piston guide. In some embodiments, the top jaw 141, the first bottom jaw 142, and the second bottom jaw 143 may be connected to the T-bone assembly 146. In some embodiments, the T-bone mount 145 may connect the T-bone assembly 146 to the telescopic arms 135, beneath the stabbing guide assembly (130, 131, and 133).

[0059] In some embodiments, the top jaw 141, the first bottom jaw 142, and the second bottom jaw 143 may clamp down on the tubular body and the tubular collar, to prevent separation under extreme torque. In some embodiments, the top jaw 141, the first bottom jaw 142, and the second bottom jaw 143 may be connected through precise geometry, which may allow the jaws to operate independently around the tubular body and the tubular collar; this geometry allows the jaws to service a range of tubular diameters.

[0060] In some embodiments, the top jaw 141 may grab onto the coupling of the tubular, and the first bottom jaw 142 and the second bottom jaw 143 may grab the body of the tubular. When secured in this configuration, the installed tubular may be held steady while the tubular to be disconnected may be screwed out of place and removed. In some embodiments, the jaws mayAmbumLaw Docket No. 6174.015 14carry the integrity or hold torque up to the joint above when used in a higher grab configuration in the event a connection is not secure, and the tubular being installed must be removed. For example, the second bottom jaw 143 may grab the tubular body, the first bottom jaw 142 may grab the coupling of the tubular, and the top jaw 141 may grab the body of the tubular being added above so the CRT, top drive, or other tool connected to the tubular from above can be released from the very top of the tubular being removed. To complete the process of removing the tubular being added to the tubular held by the first bottom jaw 142 and the second bottom jaw 143, the top jaw 141 may hold steady the tubular being added to disconnect from the CRT above and be removed by an elevator. In some embodiments, the first bottom jaw 142 and the second bottom jaw 143 may hold the installed tubular for the tubular being added to be removed.

[0061] In some embodiments, the top jaw 141, the first bottom jaw 142, and the second bottom jaw 143 may have precision machined grooves allowing for connection to and independent movement of each other, as well as the T-bone assembly 146. In some embodiments, the top jaw 141, the first bottom jaw 142, and the second bottom jaw 143 may be configured to grab tubulars of various sizes, including but not limited to 23 / 8 through 14 inches. In some embodiments, each jaw contains a hydraulic cylinder locked into a guide to one side of the jaw. In some embodiments, the guide interfaces may comprise a plate on the back of the jaw, which changes the orientation based on the extensions, which may allow the jaw to open and split apart when the tubular mounting and dismounting apparatus 100 is hinged open. In some embodiments, the opposing pairs of jaws may include guide interfaces with compatible geometry located on the opposing jaw, which may assist in connecting the grabbing pairs together for clamping. In some embodiments, the jaws may be mounted through pins and slots to the T-bone assembly 146.AmbumLaw Docket No. 6174.015 15

[0062] In some embodiments, the T-bone assembly 146 may be a length of tubing or a square hollow section with slots and pinholes for mounting the jaws, with a machined segment of material that matches the geometry of the jaws, which may provide support. In some embodiments, the T-bone assembly 146 may comprise a length of tubing behind each jaw mounting point, which may house the spring that keeps the jaw in an open position. In some embodiments, the T-bone assembly 146 may comprise a series of slots and pin holes that may mount the T-bone assembly 146 to the T-bone mount 145.

[0063] In some embodiments, the T-bone mount 145 may comprise a collection of plates to which the T-bone assembly 146 may be mounted, the position of which may be adjusted through the use of slots and pins. In some embodiments, the T-bone mount 145 may mount to telescopic arms 135, with geometry that may keep the T-bone mount 145 aligned with the center hole.

[0064] In some embodiments, the top jaw 141 may grab onto the coupling of the tubular, and the first bottom jaw 142 and the second bottom jaw 143 may be spaced out enough to allow the jaws to grab onto the collar of the tubular without adjusting the height of the tubular mounting and dismounting apparatus 100, with the exception of locking the tubular into the collar of the previous tubular, in which the tubular mounting and dismounting apparatus 100 may be extended to grab the next casing segment.

[0065] In some embodiments, each pin and component may comprise a redundant attachment mechanism to reduce the possibility of parts falling down the bore well.

[0066] In some embodiments, the tubular grabbing jaw and T-bone assembly (141, 142, 143, 145, 146) may be comprised of 44W-50W steel and 4140 steel. In some embodiments, the components ofthe tubular grabbing jaw and T-bone assembly (141, 142, 143, 145, 146) may resistAmbumLaw Docket No. 6174.015 16torque with minimal materials, so the more rigid 4140 steel may be required for components in direct contact with the tubulars.

[0067] FIG. 11 is a flowchart of an example process 1100 for operating the tubular mounting and dismounting apparatus 100. In some implementations, one or more process blocks of FIG. 11 may be executed by a human operator or a processor. The process 1100 is described in relation to an example embodiment of the tubular mounting and dismounting apparatus 100, but is not limited to any example embodiment. In some embodiments, the processor may be configured to execute instructions stored on a non-transitory computer-readable memory to perform one or more process blocks of process 1100.

[0068] In some embodiments, a system for operating the tubular mounting and dismounting apparatus 100 may comprise one or more processors operably coupled to a memory which is a non-transitory computer-readable medium. The memory may store instructions that, when executed by the one or more processors, cause the system to generate control signals configured to selectively actuate electromechanical components of the tubular mounting and dismounting apparatus 100 to precisely control the mounting and subsequent dismounting of a tubular.

[0069] As shown in Fig. 11, process 1100 may include positioning the tubular mounting and dismounting apparatus 100 about a first tubular in a retracted and closed position with the first tubular and a top coupling of the first tubular extending vertically through a base of the tubular mounting and dismounting apparatus 100 (block 1102). For example, the tubular mounting and dismounting apparatus 100 may be placed on the floor of an oil or gas rig above the bore well with at least one tubular already installed into the well bore, as described above. In some embodiments, the tubular mounting and dismounting apparatus 100 may be installed above a rotary table. In someAmbumLaw Docket No. 6174.015 17embodiments, the installed tubular may stick up vertically from the well bore and extend into the mounting plate 155 of the tubular mounting and dismounting apparatus 100. In some embodiments, the installed tubular may have a coupling installed to the top portion, which may accept the installation of another tubular. In some embodiments, the coupling of the already installed tubular may have a diameter greater than the body of the tubular and have internal grooves on the inside which may allow a tubular having exterior grooves to be screwed into place.

[0070] As also shown in Fig. 11, process 1100 may include lowering a second tubular through a guide assembly at the top of the tubular mounting and dismounting apparatus 100, where a top of the second tubular is secured (block 1104). In some embodiments, the second tubular may be secured from the top by the CRT, top drive or other device. In some embodiments, the next tubular in the sequence may be swung through the v-door of the oil or gas rig by an elevator and converted from a slanted position to a vertical position above the tubular mounting and dismounting apparatus 100, as described above. In some embodiments, the vertical tubular may be lowered by the elevator between the tubular catch assembly (105, 110, 115, 125), which may help guide the tubular into a vertical position aligned with the tubular already installed in the well bore. In some embodiments, the bottom of the tubular to be installed may comprise exterior grooves, which allow for installation into the coupling by rotating the tubular into the coupling.

[0071] As further shown in Fig. 11, process 1100 may include aligning, via a stabbing guide insert 130 of the tubular mounting and dismounting apparatus 100, the second tubular with the top coupling (block 1106). For example, as the elevator lowers the new tubular segment toward the coupling of the already installed tubular, the stabbing guide insert 130 may align the position of the tubular while protecting the threads of the tubular to be installed with the coupling of the already installed tubular, as described above.AmbumLaw Docket No. 6174.015 18

[0072] As also shown in Fig. 11, process 1100 may include converting the tubular mounting and dismounting apparatus 100 to an extended and open position and generating a connection between the second tubular and the top coupling (block 1108). For example, the tubular mounting and dismounting apparatus 100 may be converted to an extended and open position by extending hinge actuators 150 and extension actuator 137, as described above. For example, the connection between the tubular to be installed and the coupling of the installed tubular is secured by twisting the tubular to be installed as a screw may be twisted into a bolt. In some embodiments, the tubular mounting and dismounting apparatus 100 may remain in a closed and retracted position when the second tubular is being installed.

[0073] As further shown in Fig. 11, process 1100 may include determining that the connection between the second tubular and the coupling falls below a predetermined threshold (block 1110). In some embodiments, the connection integrity may be determined by a human operator or a computerized tool monitoring the torque (e.g., torque turn sensor) and time required to secure the second tubular. In some embodiments, the connection integrity may be determined by monitoring the torque required to twist the tubular into position in view of the number of turns made wherein the slope of the torque used over time fits within an acceptable threshold. In some embodiments, a secure connection may indicate that the seal created between the coupling and the tubular is air-tight or water-tight, depending on the implementation. In some embodiments, the data collected from the torque turn sensor may be used to generate a torque turn graph that includes a peak, tums-to-shoulder, graph slope, break-over torque pattern, energy, and the statistical deviation of these metrics from a baseline. In some embodiments, the operator may set an acceptable variance from the baseline to determine whether or not the connection is secure.AmbumLaw Docket No. 6174.015 19

[0074] As also shown in Fig. 11, process 1100 may include converting the tubular mounting and dismounting apparatus 100 to a retracted and closed position and securing the top coupling with the top jaw 141 and the first tubular with the first bottom jaw 142 and the second bottom jaw 143 (block 1112). In some embodiments, the tubular mounting and dismounting apparatus 100 may already be in a closed and retracted position, as described above. In some embodiments, the connection between the top coupling and the second tubular must be reversed by performing an unscrewing maneuver by the CRT, top drive or other tool secured to the top of the second tubular. In order to ensure the torque applied to the second tubular is not transferred to the first tubular, the tubular mounting and dismounting apparatus 100 may securely hold the top coupling and first tubular. When the top coupling is secured by the top jaw 141 and the first tubular is secured by the first bottom jaw 142 and second bottom jaw 143, torque may be applied by the CRT or top drive to the second tubular without transferring that torque to the top coupling and first tubular.

[0075] As further shown in Fig. 11, process 1100 may include releasing the connection between the second tubular and the top coupling and releasing the top jaw 141, the first bottom jaw 142, and the second bottom jaw 143 (block 1114). For example, the tubular mounting and dismounting apparatus 100 may rearrange the grip on the tubulars in order to proceed to the next block in the process.

[0076] As also shown in Fig. 11, process 1100 may include repositioning and securing the top jaw 141 to the second tubular, the first bottom jaw 142 to the top coupling, and the second bottom jaw 143 to the first tubular (block 1116). For example, the tubular mounting and dismounting apparatus 100 may reposition and secure both tubulars so that the CRT, top drive, or other tool connected to the top of the second tubular may be detached. In some embodiments,AmbumLaw Docket No. 6174.015 20detaching the secure connection at the top of the second tubular requires the bottom of the second tubular to be secured by the top jaw 141. In some embodiments, repositioning the top jaw 141, the first bottom jaw 142, and the second bottom jaw 143 may be performed by extending the extension actuators 137 and moving the tubular grabbing jaw and T-bone assembly (141, 142, 143, 145, 146) higher in relation to the well bore.

[0077] As further shown in Fig. 11, process 1100 may include freeing the second tubular from the top (block 1118). For example, the top of the second tubular may be secured by the CRT, top drive, or other tool, which applies torque to the second tubular and may twist into and out of place. In some embodiments, the CRT, top drive, or other tool may lift out of the top of the second tubular when the bottom of the second tubular is secured by the top jaw 141.

[0078] As also shown in Fig. 11, process 1100 may include releasing the top jaw 141 and lifting the second tubular out from the top of the tubular mounting and dismounting apparatus 100 (block 1120). For example, once the second tubular is released by the CRT, top drive, or other tool and the top jaw 141, the elevator is free to lift and remove the second tubular from the oil or gas well.

[0079] Although Fig. 11 shows example blocks of process 1100, in some implementations, process 1100 may include additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in Fig. 11. Additionally, or alternatively, two or more of the blocks of process 1100 may be performed in parallel.

[0080] FIGS. 12A-12D illustrate a non-limiting second embodiment of the telescoping arm and hinge assembly, which may comprise a telescopic arms 235, an extension actuator 237, one or more hinge actuators 250, a mounting plate 255, a main limb strut 257, and two parallel limb struts 258. The replacement of the first embodiment of the telescoping arm and hingeAmbumLaw Docket No. 6174.015 21assembly (135, 137, 150, 155) with the second embodiment of the telescoping arm and hinge assembly (235, 237, 250, 255, 257, 258) forms the second example embodiment of a tubular mounting and dismounting apparatus 200. In some embodiments, the tubular mounting and dismounting apparatus 200 comprises two of the second embodiment of the telescoping arm and hinge assemblies which mirror each other in form and function, as illustrated above.

[0081] In some embodiments, the telescoping arm and hinge assembly (235, 237, 250, 255, 257, 258) may comprise a pair of telescopic arms 235. In some embodiments, the telescopic arms 235 may be configured to extend and retract to assist with the alignment of different sump heights (i.e., the height of where the operator has set the tubular in slips and the remaining height of the tubular coupling sticking above the slip). In some embodiments, the extending and retracting movement may be controlled by an extension actuator 237. In some embodiments, the telescoping arm and hinge assembly (235, 237, 250, 255, 257, 258) may be configured to hinge open and close with a tilting motion, which may allow travel of the CRT and top drive to pass through with the next tubular segment. In some embodiments, the opening and tiling movement may be controlled by one or more hinge actuators 250.

[0082] In some embodiments, the mounting plate 255 may attach to the telescopic arms 235 via the main limb strut 257 and two parallel limb struts 258. In some embodiments, the main limb strut 257 and two parallel limb struts 258 allow the tubular mounting and dismounting apparatus 200 to hinge open while also widening the base of the tubular mounting and dismounting apparatus 200. The wider base may allow a CRT or other tool to traverse through the tubular mounting and dismounting apparatus 200 while in an open configuration with a more limited degree of angular displacement from the closed configuration.AmbumLaw Docket No. 6174.015 22

[0083] In some embodiments, the mounting plate 255 may be split to allow for the tubular mounting and dismounting apparatus 200 to be hinged open for removal. In some embodiments, the mounting plate 255 may comprise the mounting points for the telescopic arms 235 that control the opening and closing of the tubular mounting and dismounting apparatus 200. In some embodiments, the mounting plate 255 may comprise a hinge that may connect to the telescopic arms 235.

[0084] In some embodiments, the telescopic arms 235 may comprise an outer slide, an inner slide, and the extension actuator 237. In some embodiments, the outer slide may consist of two parallel vertical tubes that contain and support the inner slide, with a cavity in the center to mount the extension actuator 237, which may control the extension. In some embodiments, the telescopic arms 235 may be attached via a plate that hinges off the mounting plate 255. In some embodiments, a series of ribs may reinforce the outer slide tubes at the zenith of the inner slide’s travel. In some embodiments, the outer slide may comprise a bracket with multiple mounting points which may allow for adjustment of the angle of the tubular mounting and dismounting apparatus 200.

[0085] In some embodiments, the inner slide may comprise parallel vertical tubes that may fit within the outer slide. In some embodiments, the inner slide may comprise several tool mounting points with additional safety measures to prevent components from coming undone during operation.

[0086] In some embodiments, the telescopic arms 135 may comprise 44W-50W steel for its availability and workability. 44W-50W steel has good characteristics for the expected loads and environmental conditions. In some embodiments, the components of the second embodiment of the telescoping arm and hinge assembly (235, 237, 250, 255, 257, 258) may resist torque withAmbumLaw Docket No. 6174.015 23minimal materials, so the more rigid 4140 steel may be required for components in direct contact with the tubulars.

[0087] FIGS. 13-16 illustrates a front view, perspective view, side view, and top view, respectively, of the second embodiment of the tubular mounting and dismounting apparatus 200 and the components thereof in a closed and retracted configuration.

[0088] FIGS. 17-18 illustrates a front view and perspective view, respectively, of the second embodiment of the tubular mounting and dismounting apparatus 200 and the components thereof in an open and extended configuration.

[0089] FIGS. 19-23 illustrate a third embodiment of the tubular mounting and dismounting apparatus 300. The tubular mounting and dismounting apparatus 300 may be configured to require a smaller footprint to operate based on the movement of a grabbing assembly 340 in reference to a first tubular 301, which may already be installed in the well bore, and may be performed in only a horizontal direction or only a vertical direction.

[0090] Specifically, FIGS. 19A-19D illustrate a front perspective view, a front view, a rear perspective view, and a top view, respectively, of the tubular mounting and dismounting apparatus 300. The tubular mounting and dismounting apparatus 300 may comprise a stabbing guide assembly 305, which may be raised or lowered via a telescoping guide lift assembly 308, the telescoping guide lift assembly 308 may be attached to the base 355. The tubular mounting and dismounting apparatus 300 may further comprise a first jaw assembly 315A and a second jaw assembly 315B connected to a first telescoping jaw lift 335A and a second telescoping jaw lift 335B, where the first telescoping jaw lift 335 A and the second telescoping jaw lift 335B are connected to the base 355 via a first horizontal telescoping assembly 350A and a second horizontal telescoping assembly 350B.AmbumLaw Docket No. 6174.015 24

[0091] In some embodiments, the tubular mounting and dismounting apparatus 300 may further comprise a stabbing guide assembly 305 for aligning tubulars during connection operations. In some embodiments, the stabbing guide assembly 305 may be configured to be raised or lowered by a telescoping guide lift assembly 308, which may be attached to the base 355 and configured to provide controlled vertical positioning. In some embodiments, the vertical motion of the telescoping guide lift assembly 308 may be achieved via a dedicated linear actuator (described in greater detail with reference to FIGS 20A-20B). Furthermore, the telescoping guide lift assembly 308 may be configured to adjust the horizontal angle of the stabbing guide assembly 305, wherein a tilt actuator 309 may be utilized to facilitate the precise angular adjustment of the stabbing guide assembly 305 (described in greater detail with reference to FIGS 21 A-21C).

[0092] As described above, the tubular mounting and dismounting apparatus 300 may comprise the first jaw assembly 315A and the second jaw assembly 315B. In some embodiments, each jaw assembly may be connected to a respective vertical positioning assembly, namely the first telescoping jaw lift 335 A and the second telescoping jaw lift 335B. In some embodiments, the first telescoping jaw lift 335A and the second telescoping jaw lift 335B may be configured to raise and lower the first jaw assembly 315A and the second jaw assembly 315B on opposing sides of a tubular to enable gripping at various vertical heights along the length of the tubular body. In some embodiments, the first telescoping jaw lift 335 A and the second telescoping jaw lift 335B may be coupled to the base 355 via a first horizontal telescoping assembly 350A and a second horizontal telescoping assembly 350B, respectively. In some embodiments, the first telescoping jaw lift 335A and the second telescoping jaw lift 335B, and the first horizontal telescoping assembly 350A and the second horizontal telescoping assembly 350B may utilize at least one dedicated actuator to power the respective movements. For example, the first telescoping jaw liftAmbumLaw Docket No. 6174.015 25335 A and the second telescoping jaw lift 335B may be powered by the first jaw lift actuator 337A and the second jaw lift actuator 337B, respectively.

[0093] In some embodiments, the first jaw assembly 315A and the second jaw assembly 315B may be configured to secure and stabilize a tubular and coupling during mounting and dismounting operations. The gripping action may be initiated when the first jaw assembly 315A and the second jaw assembly 315B are moved horizontally toward the tubular from a retracted position via the first horizontal telescoping assembly 350A and the second horizontal telescoping assembly 350B. In some embodiments, the gripping mechanism may be configured asymmetrically, wherein the first jaw assembly 315A may comprise an individual actuator configured to extend a jaw to engage the tubular or coupling, while the second jaw assembly 315B may be configured as a passive engagement member. The second jaw assembly 315B may be configured to create the stabilizing grip by receiving the tubular or coupling when a jaw of the first jaw assembly 315A is extended to secure the tubular against the second jaw assembly 315B.

[0094] Specifically, FIGS. 20A-20B illustrates the tubular mounting and dismounting apparatus 300 with the telescoping guide lift assembly 308 in an extended position and the stabbing guide assembly 305 in a horizontal position.

[0095] As described above, the tubular mounting and dismounting apparatus 300 may comprise a stabbing guide assembly 305 that aligns tubulars during connection operations. The vertical movement of the stabbing guide assembly 305 may be facilitated by the telescoping guide lift assembly 308, which may be attached to the base 355. In some embodiments, telescoping guide lift assembly 308 may be configured as a multi-stage telescopic column and may comprise a plurality of telescoping extensions, wherein the number of telescoping extensions may range from two to four. In some embodiments, vertical extension and retraction of the telescoping guide liftAmbumLaw Docket No. 6174.015 26assembly 308 may be actuated by a guide lift actuator 310, which may be operatively coupled to the plurality of telescoping extensions to affect the controlled vertical positioning of the stabbing guide assembly 305. Furthermore, the telescoping guide lift assembly 308 may incorporate a tilting mechanism that is controlled by the tilt actuator 309. In some embodiments, the tilt actuator 309 may be configured to move the stabbing guide assembly 305 between a generally vertical position, wherein the stabbing guide assembly 305 is positioned away from the operational area to prevent interference with other tubular handling operations, and a generally horizontal position, wherein the stabbing guide assembly 305 is oriented to align tubulars for connection above a well bore.

[0096] In some embodiments, the guide lift actuator 310 may be mounted between the second telescoping extension and the third telescoping extension of the telescoping guide lift assembly 308. In some embodiments, a first extension chain may be mounted from the base 355, routed across a first roller positioned on the second telescoping extension, and pinned to the third telescoping extension. This configuration may utilize the motion of the guide lift actuator 310 to concurrently extend the first, second, and third telescoping extensions. Similarly, a second extension chain may be mounted from the second telescoping extension, routed over a second roller positioned on the third telescoping extension, and pinned to the fourth telescoping extension, thereby effectuating the extension of the fourth telescoping extension and the stabbing guide assembly 305. In some embodiments, the deployment of the stabbing guide assembly 305 during operations, such as when running casing, may involve raising the telescoping guide lift assembly 308 to a height just above the set stump height, which height may be regulated by limiting the travel of the stabbing guide lift cylinder. Additionally, the tilt actuator 309 may be utilized during the phase to tilt the stabbing guide assembly 305 from a generally vertical position to a generallyAmbumLaw Docket No. 6174.015 27horizontal position, rendering the stabbing guide assembly 305 parallel to the set stump height for tubular alignment.

[0097] Specifically, FIGS. 21A-21C illustrate how the stabbing guide assembly may engage with a second tubular 303, which is installed onto the coupling 302, which is installed onto the first tubular 301 already engaged in the wellbore.

[0098] In some embodiments, the stabbing guide assembly 305 may be maintained in a closed configuration by a first biasing element 304 A and a second biasing element 304B, which may bias the components of the stabbing guide assembly 305 into a closed position. The stabbing guide assembly 305 may initially be positioned in a generally vertical orientation and may transition to the generally horizontal position via the operation of the tilt actuator 309. In some embodiments, the tilting motion of the stabbing guide assembly 305 may be converted into an opening force by a first guide 306A and a second guide 306B. The first guide 306A and the second guide 306B may comprise geometry that, when the stabbing guide assembly 305 is pushed down onto the second tubular 303, forces the first biasing element 304 A and the second biasing element 304B to release. The release of the biasing elements may allow the stabbing guide assembly 305 to open and complete its transition to the generally horizontal position, encompassing the second tubular 303 in an interior cavity.

[0099] Further, the interior cavity of the stabbing guide assembly 305 may comprise a first interior guide 307A, a second interior guide 307B, and a third interior guide 307C, which may be angled similarly to a funnel to guide a tubular entering from the top to align with the center of the interior cavity which may be centered over the well bore. In some embodiments, the first interior guide 307A, the second interior guide 307B, and the third interior guide 307C may comprise an impact-resistant plastic, such as Ultra-high-molecular-weight polyethylene, Nylon,AmbumLaw Docket No. 6174.015 28TEFLON, or Polyurethane. The underside of the stabbing guide assembly 305 may feature a sloping geometry to allow for a degree of misalignment correction with the telescoping guide lift assembly 308. Additional misalignment correction capability may be provided by pivots on the stabbing guide assembly 305, vertical slides on the stabbing guide assembly 305, and a depth slider on the stabbing guide assembly 305 mount. The stabbing guide lift cylinder may be configured to retract, and the hydraulic components may comprise pressure sensors configured to halt the movement of the stabbing guide assembly 305 once contact has been made with the stump. These various points of movement may be configured to grant the stabbing guide assembly 305 the flexibility to align with the stump and correct misalignments without requiring the halting of the overall operation. Once the stabbing guide assembly 305 has aligned the tubular, the next tubular length may be lowered into the stabbing guide assembly 305 to ensure precise alignment.

[0100] In some embodiments, the interior cavity may also have an upward-facing funnel, which may align tubulars that the stabbing guide assembly 305 is being lowered onto. Also, the underside of the interior cavity may comprise a shelf that halts the stabbing guide assembly 305 from being lowered into the interior cavity past the point of the shelf, as shown in FIG. 21C.

[0101] Specifically, FIGS. 22A-22B illustrate how the tubular mounting and dismounting apparatus 300 may secure a grip on the coupling 302, and the first tubular 301 with a top jaw 241, a first bottom jaw 342, and a second bottom jaw 343.

[0102] In some embodiments, the first telescoping jaw lift 335 A and the second telescoping jaw lift 335B may be utilized to elevate the first jaw assembly 315A and the second jaw assembly 315B, respectively, to an appropriate vertical height. In some embodiments, the vertical adjustment may ensure the accurate alignment of the first jaw assembly 315A and the second jaw assembly 315B with the coupling 302 and the first tubular 301 already engaged in theAmbumLaw Docket No. 6174.015 29wellbore. Following this vertical alignment, the first horizontal telescoping assembly 350A and the second horizontal telescoping assembly 350B may be utilized to move the first jaw assembly 315A and the second jaw assembly 315B horizontally inward toward the wellbore. This inward horizontal movement may position the first jaw assembly 315A and the second jaw assembly 315B proximate to the first tubular 301, preparing them for gripping and securing.

[0103] Specifically, FIGS. 23A-23B illustrate the tubular mounting and dismounting apparatus 300 with the first telescoping jaw lift 335A and the second telescoping jaw lift 335B in a lifted position, and the first horizontal telescoping assembly 350A and the second horizontal telescoping assembly 350B in a closed position. Specifically, FIG 23C illustrates a close-up view of the first jaw assembly 315A and the second jaw assembly 315B secured to the second tubular 303, the coupling 302, and the first tubular 301.

[0104] In some embodiments, the gripping operation may convert the tubular mounting and dismounting apparatus 300 from a lowered and open configuration of the first jaw assembly 315A and the second jaw assembly 315B. In some embodiments, the first jaw assembly 315A and the second jaw assembly 315B, which may be referred to as the Tri- Jaw carriage, may be achieved by the first telescoping jaw lift 335 A and the second telescoping jaw lift 335B, utilizing chains mounted over rollers within the middle extension of each lift assembly. In some embodiments, the raising sequence may be initiated while the stabbing guide assembly 305 is tilted clear of the first jaw assembly 315A and the second jaw assembly 315B.

[0105] In some embodiments, the first telescoping jaw lift 335 A and the second telescoping jaw lift 335B may continue to raise the jaw assemblies until flappers, which may be positioned on the first bottom jaw 342 or the second bottom jaw 343, make physical contact with the bottom surface of the coupling 302. These flappers may be spring-loaded and may beAmbumLaw Docket No. 6174.015 30configured to contact any diameter coupling, even when the jaw assemblies are not yet engaged by their individual actuators.

[0106] In some embodiments, the vertical position achieved by the contact of the flappers against the coupling 302 may position the first bottom jaw 342 or the second bottom jaw 343, beneath the coupling 302. Furthermore, the length dimension of T-bones associated with the top j aw 241 , the first bottom j aw 342, and the second bottom j aw 343 may ensure that the top j aw 241 , the first bottom jaw 342, and the second bottom jaw 343 do not clamp directly onto the coupling 302 itself. This specific clamping schema, wherein the grip is secured beneath the coupling 302 on the first tubular 301 and the second tubular 303, may be configured to allow a Top Drive system to break out of a suspended casing length. During this breakout operation, the first jaw assembly 315A and the second jaw assembly 315B may be configured to handle the entire weight and torque load imposed by the casing segment suspended in the wellbore. Upon completion of this stage of operation, the tubular mounting and dismounting apparatus 300 may be configured to return to its original open and lowered position.
