Abstract: A method of heating a chemical solution used in a well bore having a tubing string is disclosed. The well bore will intersect a hydrocarbon reservoir. The method will include providing a diesel engine that produces heat as a result of its operation. The engine will in turn produce a gas exhaust, a water exhaust, and a hydraulic oil exhaust. The method would further include channeling the exhaust to a series of heat exchangers. The method may further include flowing a treating compound into the heat exchangers and heating the treating compound in the series of heat exchangers by heat transfer from the exhaust to the treating compound. The operator may then inject the treating compound into the well bore for treatment in accordance with the teachings of the present invention. One such method would be to inject utilizing a coiled tubing unit. The novel thermal fluid heating system is also disclosed.

Abstract: A method for running tools in an oil or gas well includes the running of an elongated small diameter tubing string from a coil stored on a reel down into the oil and gas well. A fluid conveying carrying tool is secured to the lowermost distal end portion of the coil tubing string so that fluid can circulate from the coil tubing wound upon the reel into a tool assembly. Fluid (or pressurized gas) can be introduced into the well through the tubing so that it circulates through the tubing and then into the tool carrier. A tool such as a wire-line tool is supported by the tool carrier so that pinching can be applied to the tool with the coil tubing string with the tool carrier forming a load transfer interface between the coil tubing string and the wire-line tool.
