Abstract:
A single tractor unit is provided for pulling a trailer, in which the tractor itself drives a plurality of hydraulic motors which control a crane unit, a coiled tubing injection unit, and the pumps and motors associated with a liquid nitrogen system which is used for injecting gaseous hydrogen into a workover well with coiled tubing. In an alternative mode, the liquid nitrogen system is replaced with nitrogen generators or tanks of compressed nitrogen gas. In another alternative embodiment, a separate engine, preferably mounted with the other equipment on a trailer, skid, or barge, replaces the single tractor engine for driving the plurality of hydraulic motors. In yet another embodiment, a single engine drives a plurality of well treating systems on an off-shore installation.
