Filed:

Apr 22, 2002

Appl. No.:

10/127092

Inventors:

James B. Crawford - Lafayette LA 70503
Edward R. Lamb - Lafayette LA 70508

International Classification:

E21B 1922

US Classification:

166 772, 166 901

Abstract:

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 earths 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.

US Classification:

166379, 166 772, 166 901

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.

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.
