Abstract: A system and method for stall recovery of mud motors may be implemented in a steering control system. The stall recovery system and method may involve automatic detection of a stall of a mud motor during drilling controlled by the steering control system, and may respond to the stall in a rapid and controlled manner to avoid or minimize damage to the mud motor, such as by immediately reducing mud pressure and stopping rotary drilling, if used, faster than a typical human operator could perform. The stall recovery system and method may farther take actions to automatically restart drilling.

Abstract: 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.

Abstract: A method and apparatus to move a modular drilling rig in formation wherein the drilling rig includes a plurality of self-propelled modules to facilitate the movement of the rig while all systems are intact and fully operational. The apparatus includes a plurality of wheel assemblies which are steerable to guide the modules during movement. The apparatus also includes a propulsion system for each of the modules to drive each of the modules during movement. A steering control and position feedback system is also provided for determining the relative position of each module with respect to the master module. This control and feedback system provides feedback to the steering control and feedback systems of other modules in order to move the modules in a formation.

Abstract: An apparatus and method to assemble and disassemble a valve cover locking screw assembly for a reciprocating pump module block. The module block has a bore, a removable valve cover closing the bore, and a valve cover locking ring securable to the block and surrounding the bore with internal threads. A valve cover locking screw has cylindrical walls with external threads, a closed top, and an open bottom. A plurality of threaded bolts engage a plurality of threaded openings through the cylindrical walls of the locking screw so that the bolts force the valve cover against the module block thereby creating a fluid tight seal.

Abstract: A process to lower or raise a drilling rig for transportation wherein the drilling rig includes a mast and a top drive. The process to lower includes the steps of moving the top drive within the mast with a vertical guide and torque reaction mechanism to a locked position and locking the top drive to the mast with a locking mechanism. The mast and the top drive are lowered together from a vertical position to a horizontal position. The combined mast and top drive may then be transported in the horizontal position without disconnecting electrical, mud line or other services.

Abstract: A liner retention system for a reciprocating pump having a piston and a piston rod operating in a cavity of a frame. The system includes a cylindrical liner for the piston and piston rod, the liner having a radially extending external shoulder. A liner clamp plate has a central opening receivable over the liner and a plurality of stud apertures. A plurality of studs extends from the frame, each stud terminating in a threaded end spaced from a module block. At least one compression sleeve has an inside diameter larger than an external diameter of the stud. Tensioner mechanism secures each stud to the liner clamp plate to thereby secure the cylindrical liner to the module block.

Abstract: A method of self-aligning connections for a two section mast. The method includes the steps of transporting the elongated bottom mast section to a guide frame adjacent to a well site, the bottom mast section having a pair of front legs and a pair of rear legs. An elongated top mast section is transported to the well site, the top mast section having a pair of front legs and a pair of rear legs. The legs of the bottom mast section are positioned slightly below a level of the legs of the top mast section. Thereafter, the bottom mast section is raised slightly to order to engage the top mast section while simultaneously aligning the mast sections together. The sections are thereafter pinned together.
