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 nitrogen 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. Coiled tubing is described which embeds one or more stainless steel tubes for transporting gas, liquid or other fluids therethrough and also includes the use of one or more cords which are used to assist in maintaining the coiled tubing as having a circular cross-section, with such cords either being electrical or non-electrical in nature.
