Abstract: Wrench systems, methods, and related apparatus are used for determining angular misalignment in wrenches that make up and/or break out tubular connections. The systems, methods, and related apparatus are used to continuously monitor for angular misalignment and automatically correct for angular misalignment. A wrench system includes a first clamp assembly, a second clamp assembly, and a positioning subsystem. The positioning subsystem includes one or more sensor tracks mounted to the first clamp assembly, and one or more position sensors mounted to the second clamp assembly. The one or more position sensors are configured to interface with the one or more sensor tracks to measure an angular position of the second clamp assembly relative to the first clamp assembly.

Abstract: A horizontal directional drilling machine includes a drill string rotational drive unit having an output member configured to connect with and selectively drive rotation of a drill string, the rotational drive unit including a hydraulic motor. A hydraulic circuit has a configuration that puts the motor in a drive mode to apply torque and a second configuration that puts the motor in a freewheel mode disabled from applying torque. The hydraulic circuit includes a first fluid flow path for connecting the hydraulic motor through a first rotary ball valve to one of an inlet side and an outlet side of a drive pump, and a second fluid flow path for selectively connecting the hydraulic motor through a second rotary ball valve to the other side of the drive pump. In the first configuration, there is no pressure drop across the first and second rotary ball valves.

Abstract: A system including a spinner assembly that includes a spinner subassembly which includes a spinner configured to engage a tubular, and a drive gear coupled to the spinner, with the drive gear configured to drive rotation of the spinner, and the encoder configured to count teeth of the drive gear as the drive gear rotates. A controller configured to determine a number of revolutions of a tubular that are needed to thread the tubular to a tubular string based on data from the encoder. The controller is also configured to determine when the tubular is unthreaded from the tubular string based on data from the encoder.

Abstract: A system including a stabbing guide with a plurality of guide elements, an engaging element, and a linkage assembly that couples the plurality of guide elements to the engaging element, where rotation of the engaging element relative to the plurality of guide elements drives the linkage assembly and, via the linkage assembly, moves the guide elements radially relative to a center axis of the stabbing guide.

Abstract: A high-temperature and high-pressure simulator for a deep in-situ environment is provided. The simulator includes a high-fidelity sample chamber, where a lower end of the high-fidelity sample chamber is provided with a bottom cylinder. A lower end of the bottom cylinder is provided on a base. A piston rod of the bottom cylinder extends into the high-fidelity sample chamber, and an upper end of the piston rod is provided with a rock sample seat. An upper end of the high-fidelity sample chamber is provided with a rock sample cap. The top of the high-fidelity sample chamber is sealed by an end cap of the high-fidelity sample chamber. An upper end of the end cap of the high-fidelity sample chamber is provided with a multi-section coring drill chamber. The uppermost section of the coring drill chamber is connected to a lift cylinder.

Abstract: A method for conducting subterranean operations can include engaging a tubular with a pipe handler, moving the tubular with the pipe handler to a new location, disengaging from the tubular at the new location, determining, via a rig controller, an estimated location of the tubular based on the new location at which the pipe handler disengaged from the tubular, determining, via a machine learning module of the rig controller and one or more imaging sensors, a deviation from the estimated location of the tubular.

Abstract: A technique facilitates landing of a subsea component, e.g. a tubing hanger, by utilizing a poppet valve to provide an indication of proper landing. The poppet valve is combined with the tubing hanger or other subsea component and oriented to engage a corresponding landing surface. A pressure line is routed to the poppet valve, and the poppet valve is biased to an open flow position with respect to the pressure line during deployment. If the subsea component is properly landed, the corresponding landing surface is able to shift the poppet valve to a closed position. The closed position may be verified via pressure testing through the pressure line.

Abstract: Systems and methods for preventing improper lifting of tubular members are described, in which sensing devices are used to detect when a tubular reaches a selected position within a lifting device suitable for engagement, and/or to detect when a lifting operation is initiated that would exceed the capacity of a lifting device. Operators are engaged with the tubular member and provided with a preselected force corresponding to the weight of one or more tubular members, such that when the weight of a lifting operation exceeds the preselected force, an audible device may be actuated responsive to sensor output, to immediately alert individuals, such that the improper lifting operation may be halted. Similarly, an audible device may be actuated responsive to sensor output when a tubular member reaches a selected position within the lifting device, such that additional movement may be ceased.

Abstract: Present embodiments are directed to a gripping device configured to couple with a pipe element. A housing of the gripping device is configured to extend over and at least partially around a distal end of the pipe element. Torsional clamp devices are configured to engage an outer circumferential surface of the pipe element with frictional engagement features that extend radially inward from the housing. A sealing mechanism is configured to shift a pipe seal relative to the housing and into engagement with the distal end of the pipe element and to facilitate fluid flow through the gripping device into the pipe element.
