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.

Three in one combined power unit for nitrogen system, fluid system, and coiled tubing system

A single tractor unit is provided for pulling a tractor, 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 one or more nitrogen generators which gather nitrogen from the earth's atmosphere to be pumped through the coiled tubing into the well being treated. Alternatively, the gaseous nitrogen source is one or more tanks of compressed nitrogen gas.
