A method of unthreading an up-hole drill rod from a down-hole drill rod includes breaking a joint using a first vise and a second vise, the second vise being in a first axial position, rotating the up-hole drill rod to fully unthread the up-hole drill rod from the down-hole drill rod, moving the second vise to a second axial position and moving the unthreaded up-hole drill rod away from the down-hole drill rod and into alignment with a rod loading region of the rod storage structure, after the up-hole drill rod is aligned with the rod loading region of the rod storage structure, extending the rod handling device to receive the up-hole drill rod in rod receivers, moving the second vise axially to the first axial position, and retracting the rod handling device to move the up-hole drill rod to the rod storage structure.

A method of building and operating a land-based drilling rig with a high-capacity mast include providing a platform collapsed on a substructure over a proposed well drilling location and building the high-capacity mast in a horizontal condition by attaching a lower portion of the high-capacity mast to the platform. The high-capacity mast having an opening formed therein sized to accommodate four Range 2 pipes or three Range 3 pipes. The high-capacity mast may be raised from the horizontal condition to a vertical condition by pushing the side of the high-capacity mast to pivot the high-capacity mast about a pivot point on the platform. The platform may be raised from a collapsed condition to a raised condition over the substructure. Some implementations include dual racking boards on the high-capacity mast.

An automatic auxiliary workover rig includes a silo body arranged on a skid-mounted baseplate, a guide-roller type elevator, a random-folding type traveling block rigid guide device, a truck-mounted folding type manipulator, a slip, a flatcar up-down adjustment device, a detecting and conveying device, and a transfer device. The automatic auxiliary workover rig cooperates with an existing workover rig to complete ascending and descending of a sucker rod of an oil pipe during minor overhaul. The slip is located above a wellhead blowout preventer, and is configured to clamp and loosen the oil pipe of a wellhead. The silo body is configured to store and output the oil pipe. The truck-mounted folding type oil pipe manipulator garbs the oil pipe and then ascend and descend the oil pipe, meanwhile the manipulator is equipped with a height adjusting device to realize flexible joint in tube thread fastening and unfastening.

A tailing arm and tubular positioning device with an arm base unit, control module and an arm engaging a hydraulic power unit. A side shift assembly attaches to an opposite end of the arm and fluidly connects to the hydraulic power unit. A lower roller assembly secured to the side shift assembly and fluidly connected to the hydraulic power unit and an upper roller assembly engages the hydraulic power unit. The control module is configured to move upper and lower rollers to support a tubular and maintain contact with the tubular through a range of motion of the tubular, position the upper and lower rollers symmetrically and in snug contact with the tubular, shift the tubular longitudinally with the upper and lower rollers using roller cylinders and rotation of the arm, shift the tubular laterally with the side shifting assembly, and release the tubular.

A catwalk for transporting tubular members of a well system includes a substructure, a first transport frame pivotally coupled to the substructure at a first pivotal joint and including a first support surface configured to engage the tubular member, a second transport frame pivotally coupled to the first transport frame at a second pivotal joint and including a second support surface configured to engage the tubular member, and a strut pivotally coupled between the second transport frame and the substructure, wherein the strut is configured to transfer the weight of the tubular member from the second transport frame to the substructure when the tubular member is transported between the first support surface and the second support surface.

Some embodiments of the present disclosure relate to pipe handling apparatus that comprise a base, an elongate door, a pipe carrier and a lift member. In some embodiments the lift member is pivotally connected at one end to the base and pivotally connected to the pipe carrier at the other end. In some embodiments, the apparatus includes further features that provide full capture of the pipe carrier by the elongate door and the lift member. In some embodiments the pipe carrier is moved substantially along the elongate door by a combined actuator, shiv and cable system.

A tubular handling system can include a bridge disposed in a horizontal orientation above a horizontal storage area, a tubular lift system that can transport a tubular in a horizontal orientation between the horizontal storage area and an intermediate storage location, and a pipe handler, moveably coupled to the bridge, that can transport the tubular between the intermediate storage location and a rig floor. Also provided is a method for handling tubulars that can include operations of delivering or retrieving a tubular in a vertical orientation to or from a rig floor, transporting the tubular between the rig floor and a bridge, rotating the tubular between vertical and horizontal, retrieving or delivering the tubular to an intermediate storage location, and raising or lowering the tubular between the intermediate storage location and a horizontal storage area while maintaining the tubular in the horizontal orientation.

A vessel is adapted to perform subsea wellbore related operations involving a riser string between the subsea wellbore and the vessel, e.g. drilling and/or wellbore intervention. The vessel includes a hull having a deck, and a riser storage hold present within the hull below the deck. The riser storage hold includes storage racks adapted to store therein parallel stacks of multiple riser sections and/or pre-assembled riser stands in horizontal orientation. The vessel has an elongated riser transfer opening between the deck and the roof, the riser transfer opening extending in a direction parallel to the storage racks, the riser transfer opening having a length and a width so as to allow for transfer of a single riser section or a single riser stand in horizontal orientation via the riser transfer opening out of and into the riser storage hold, wherein the risers' handling system is suitable to work at the same time with two different lengths.
