Abstract: A system using a semi-tractor and the engine of the semi-tractor to heat a fluid from a cryogenic temperature to approximately room temperature while pressurizing the fluid is disclosed. The system is mounted on the frame of the semi-tractor and preserves the ability of the semi-tractor to haul a standard semi-trailer tanker. The system uses a semi-tractor having an internal combustion engine cooled by a liquid coolant, a cab with a sleeper section. The sleeper section is used as a control cabin for allowing an operator to monitor the operation of the system in the field. The frame includes a fifth wheel type coupler that is mounted forward of the rearmost wheel axle of the semi-tractor.

Abstract: A method for delivering a tubular to a well centered drill axis includes rotating a transfer arm to which a tubular is secured about a first axis from a horizontal position to a vertical position at which a center of gravity of the transfer arm and the tubular is disposed above the first axis; and rotating an upper link of the transfer arm about a second axis while oppositely rotating a clamp support beam about a third axis from the vertical position toward the drilling apparatus while a lower link remains in the vertical position. In delivering the tubular to a drilling apparatus, a tubular supply apparatus controls the speed and acceleration of the tubular without having actuators thereof change between compression and tension states or between rotational states.
