A hydraulic fracturing system has a pump driven by an electrically powered motor. The pump pressurizes fluid which is piped into a wellbore to fracture a subterranean formation. The pump and motor are mounted on a trailer that is hitched to a tractor. A platform assembly is mounted onto the trailer, and which is selectively moveable between deployed and stowed configurations. The platform assembly includes a platform, a lateral rail assembly mounted to the platform, and gates on the forward and aft ends of the platform. The rail assembly and gates define a safety barrier to prevent operations personnel from falling off the platform. In the stowed configuration the platform assembly is anchored in place over wheels on the trailer. In the deployed configuration, the platform assembly provides work surface so that operations personnel can readily access the pump on the trailer.

A transportable rig apparatus provides single operator control for moving pipe into and out of a wellbore. A transportable control van houses the operator. A rig carrier is utilized to transport the mast. A pipe tong is mounted in the mast and is remotely operable from the control van. Rig blocks which move up and down in the mast are remotely operable from control van. A skid mounted pipe moving member moves pipe to the mast assembly and away from the mast assembly. The pipe moving member remotely is operable from the control van. A pipe tub stores pipe and a pipe tub transfer system is operable for moving pipe from the pipe tub to the pipe moving member and for moving pipe from the pipe moving member to the pipe tub.

A system for detecting an underground cross-bore in accordance with one exemplary embodiment includes a mechanical sensing device attached to an underground travel element to form a combination adapted for underground travel. The mechanical sensing device senses at least a first underground condition wherein the combination is ensconced in an underground bore and a second underground condition wherein the sensing device senses entry into a pipe cavity. The mechanical sensing device desirably can provide a signal identifying entry into a pipe cavity.

A completion system and method adapted for use in wells having long lateral boreholes includes a mast assembly, a pipe handling mechanism, a pipe arm, a pipe tub, a pump/pit combination skid, a rig carrier, and a control system. The mast assembly can extend in a generally vertical direction, e.g., perpendicular to the rig carrier and/or the earth's surface, such that the rig can be placed directly adjacent to a wellbore, and the top drive or a similar drive system can be engaged with and move along the mast while remaining above the wellbore. The top drive can be engaged with a support fixture that resists torque and rotation during operation. The support fixture can in turn be engaged with the mast to transfer torque forces to the mast while being vertically movable along the mast to enable positioning of the top drive.

An apparatus for driving piles or drilling holes includes a self propelled vehicle with a mounting platform supported by the vehicle. A lifting and positioning arm is provided having a mounting end and a remote end. The mounting end is mounted to the platform. The arm rotates about a vertical axis relative to the platform wherein the remote end of the arm is positioned in a selected radial orientation relative to the platform. The arm pivots about a substantially horizontal axis relative to the platform wherein the arm is moved up and down to position the remote end of the arm at a selected height above or below the platform. The arm extends and retracts wherein the remote end of the arm is positioned a selected distance from the platform. A pile driver or drill assembly is pivotally mounted to the remote end of the arm.

A mobile foxhole excavator (MFE) is mounted on a standard military vehicle for transport and positioning. The excavator is powered by a self-contained internal combustion engine, which powers a hydraulic system for positioning an auger mast in three mutually perpendicular planes (horizontal, vertical and lateral) to permit the auger to bore holes at any desired angle between vertical, downward, and horizontal, as well as boring at various overhead angles between horizontal and near vertical. A single hydraulic motor is used to operate the boring auger, as well as various hydraulic cylinders to effect the desired positioning of the auger mast.
