A drilling rig includes a rig floor, first and second support structures, a mast, a lower drilling machine, a continuous drilling unit, an upper drilling machine, and an upper mast assembly. The rig floor includes a V-door defining a V-door axis extending perpendicularly from the side of the rig floor that includes the V-door. The first and second support structures define a traverse corridor having a traverse corridor axis, wherein the traverse corridor axis is perpendicular to the V-door axis. The drilling rig may be used for continuous drilling of a wellbore.

A boom system for utility service lines (such as cables, wires, hoses, pipes, etc.) for a drilling rig. The mobile boom system includes a skid with posts and one or more booms pivotally attached to each post. One or more articulating booms attached to a first post can support and carry the service lines connected to the sources and one or more articulating booms attached to the second post can support and carry the service lines connected to a drilling rig, or to a boom extending from a drilling rig. The mobile articulating boom system can include means for moving and selectively positioning the mobile articulating boom system at a drilling site. The mobile boom system can be adapted so that it has first, second, and third booms which can be placed in a closed position and fit within a perimeter defined by the skid for easier transportation to and from a drilling site.

A drilling rig having a lift arm, which may be an auxiliary lift arm provided in addition to a primary lifting cable system of the drilling rig. The lift arm may be configured to hoist and/or manipulate drill collar, drill pipe, or other drilling pipe or conduit. The lift arm may be coupled to a mast of the drilling rig and may have a cantilevered boom extending therefrom. The boom may be configured to pivot between alignment, or near alignment, with well center and a racking board. The lift arm may additionally have a pipe engaging element coupled to the boom. The pipe engaging element may be configured to couple to stands or lengths of drilling pipe. The pipe engaging element may be raised and lowered together with or relative to the boom via a lift line controllable via a hydraulic cylinder, winch, or other suitable mechanism for withdrawing and releasing the line.

A walking system for a workover rig or completion rig mounted on a motor vehicle. The walking system includes a main platform having ramps and tracks for the motor vehicle to drive up onto and a base beam extending perpendicularly on both sides of the main platform to act as outriggers for stability. The system further includes a workstring platform for storing tubulars that make up the workstring, which is elevated above a wellhead. The main platform and base beam have walking assemblies for lifting the rig and moving it laterally so that it can be positioned over the wellhead for workover or completion operations.

A mast assembly for a drilling rig includes a mast formed from a plurality of mast subunits. The mast assembly includes a lower drilling machine, upper drilling machine, and upper mud assembly, each of which is coupled to and movable vertically relative to the mast. The mast subunits are separable when the mast is in a transport configuration such that the LDM is positioned in a first subunit and the UDM is in a second subunit of the mast when the mast is in the transport configuration. The mast assembly may be used during a continuous drilling operation.

A drilling rig system includes a drilling rig that includes a mast, a pair of hydraulic pistons coupled to a pair of front legs of the mast and configured to apply a first force to the mast, the first force acting in a direction opposing a force generated by a weight of the mast, a plurality of raising lines coupled to a crown block of the mast and to a pair of rear legs of the mast opposite the front legs and configured to apply a second force to the mast, the second force acting in a direction opposing the force generated by the weight of the mast, and a drawworks assembly coupled to the plurality of raising lines and configured to apply a force acting away from the crown block of the mast to at least one of the plurality of raising lines to generate the second force.

A mobile service rig includes an onboard rechargeable electric power storage system (e.g., a battery, supercapacitor, etc.) for powering the rig's hoist and drive wheels. Under battery power, the rig travels overland to service wellbores at various wellsites. Once at a wellsite, a pumpjack at the site is de-energized, and the hoist proceeds to remove and reinstall wellstrings (e.g., tubing and sucker rods). While the pumpjack is de-energized, the rig's onboard rechargeable electric power storage system taps into the electric power source normally used for the pumpjack. The drive wheels and hoist can drain the rig's rechargeable electric power storage system, but the pumpjack's electric power source can gradually recharge it while the rig is servicing the wellbore. Moreover, when the hoist lowers the wellstring back down into the wellbore, the energy generated by that operation is recovered and used for replenishing the rig's rechargeable electric power storage system.

A system for monitoring the components of a skid module comprising a load driven by a motor associated with an automatic transmission using lockup technology includes a smart box associated with the skid module. Exemplary loads include mud pumps and generators. A plurality of sensors are associated with skid components and electrically associated with the smart box. The smart box uses at least some of said plurality of sensors to determine if the lockup technology is working properly and generates a warning when a lockup failure is detected. The skid module status is reported to at least one of a local display device or a remote display device in communication with the smart device over a network.
