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: Apparatus and method for treating solids contaminated by alkaline earth metal scales which have naturally occurring radioactive material entrained throughout the scale. The equipment and method of the present invention may be used on site to clean stored contaminated solids so that as a result of the treatment the solids may be disposed of as non-hazardous oil field waste and the radioactive isotopes may be dispersed in aqueous solution. The apparatus and method of the invention provide for placing contaminated solids and a treatment fluid in a fluid contact zone which is designed to provide optimum chemical activity for treating the contaminating scale so as to release the radioactive isotopes into solution. Once the release of the isotopes is complete to a target level of radioactivity, the treating fluid is then separated from the solids which are then reduced to non-hazardous oil field waste.

Abstract: Alkaline earth metal scales, particularly barium sulfate and strontium sulfate, and silica-based scales, particularly potassium fluorosilicate, are removed from industrial processing equipment, tubular goods, and other scaled materials with a composition comprising sufficient potassium base to provide an overall system pH of between about 12.0 to about 14.0, a polyaminocarboxylic acid, preferably EDTA, a hydroxycarboxylic acid synergist, a pH buffering agent, a wetting agent, and optionally a sodium base.

Abstract: A filament rope may be produced continuously by the method and apparatus of this invention. In an upper portion of a frame of the apparatus is a unit having strand carrying spools that move about to braid the strands into a core of the rope. During braiding the strands overlap to form sets of pairs of transversely aligned openings which decrease in size as the rope core is drawn away from the braiding unit by a tension wheel assembly. While the openings are still large, a filament length carried by a first cylinder passes through one pair of strand openings. The cylinder then is withdrawn and the filament length severed leaving a filament segment in that pair of openings. Next, a second filament segment is placed in the other strand opening pair by a second cylinder. After filament segment insertion a tamping tool engages the strands and inserted filament segments to promote opening size reduction and improve formation of a compressive fit by the strands on the filament segments.
