A vehicle support structure, which in petroleum wellsite operations is commonly called a rig mat or a ground stabilizing mat, includes: a main body including an upper surface, an underside, a front end and a rear end, the main body defining a planar structuring with a thickness; a front pad coupled to the main body and positioned adjacent the front end; a rear pad coupled to the main body and positioned adjacent the rear end, the front pad and the rear pad each configured to be moveable between a supporting position protruding from the underside of the main body and a retracted position in plane or retracted from the underside; a front pad drive mechanism for the front pad, the front pad drive mechanism configured to drive the front pad to move between the supporting position and the retracted position and to move the front pad forward and backwards and side to side relative to the main body; and a rear pad drive mechanism for the rear pad, the rear pad drive mechanism configured to drive the rear pad to move between the supporting position and the retracted position and to move the rear pad forward and backwards and side to side relative to the main body, the front pad and the rear pad being configured to operate to support the main body in an elevated position relative to a ground surface and configured to move the main body forward and backwards and side to side relative to the front pad and the rear pad and over the ground surface. In use as a rig mat, a method for well site operations includes: placing the rig mat at a position on a first well site; positioning a rig on the rig mat; and adjusting the position of the rig mat while the rig remains supported on the rig mat such that the rig is centered on a wellhead of the well site.

Vehicle support structure for a worksite

An automated rig apparatus for drilling or servicing a well is provided. The apparatus can include a motor vehicle having a frame, and a hinged derrick mast pivotally attached to the frame. The apparatus can further include a rack disposed in the mast and a carriage assembly with pinion motors configured to travel up and down the rack when the mast is raised to a vertical position. A tool carrier configured to receive a top drive unit or a power swivel unit can be attached to the carriage assembly. The apparatus can further include a movable platform and an operators cab configured to be moved to a desired position relative to the derrick mast when the mast is raised to a vertical position. The apparatus can further include a hydraulic drive assembly to operate the apparatus, and a mud pump and manifold for pumping drilling mud.

Automated drilling/service rig apparatus

For wellbore operations, a pipe handler moves pipe up to a rig floor. A pipe loader moves pipe from a presented position into alignment with well center. The pipe handler moves pipe up to a slanted presented position. The slanted presented position can be adjusted by manipulating the drive system.

Pipe handler and pipe loader for a well rig

A safety valve handling apparatus for a well operation rig includes: a mounting structure for connection to the rig; a clamp for engaging a safety valve and configured to permit rotation of the safety valve within the clamp while the safety valve remains engaged by the clamp; and an arm connected between the mounting structure and the clamp, the arm being movable and adjustable to permit movement of the clamp relative to the mounting structure. The safety valve handling apparatus can be used for controlled safety valve handling on a well operation rig, even one oriented for a slanted operation.
