Abstract: A method for reducing the friction forces between tubulars, for example coiled tubing in casing includes mixing a selected suspending agent and surfactant and polymer particles in oil, then adding the mixture to water and pumping the mixture down the tubing. The mixture is particularly useful in coiled tubular drilling inside casing of an oil or gas well. The formulation has also been found to reduce corrosion on metal surfaces.

Abstract: A method for reducing corrosion on the exterior or interior surface, for example coiled tubing and casing, includes mixing a selected surfactant and particles of a polymer in oil, then adding the oil to water and contacting the surfaces of the tubing with the mixture.

Abstract: A liquid mixture reduces the friction between two surfaces, at least one of which is moving with respect to the other such as tubing moving within the casing of an oil or gas well. The mixture includes an oil, a suspending agent, polymer particles and a surfactant.

Abstract: A method for reducing the friction forces between tubulars, for example coiled tubing in casing, is disclosed. The method includes mixing a selected surfactant and particles of TEFLON in oil, then adding the oil to water and pumping the mixture down the tubing. The mixture is particularly useful in coiled tubular drilling inside casing. The formulation has also been found to reduce corrosion on metal surfaces.

Abstract: A system for blending polymers and other chemicals in an aqueous liquid is provided. Static mixers and tubes, preferably in one or more tube bundles, provide a volume sufficient to allow a residence time in the system to hydrate a polymer. Static mixers may be integrated with a tube bundle. The system may be mounted on a portable base such as a trailer. The concentration of polymer and chemicals in water may be controlled by a controller. A variable speed electric pump may be utilized to precisely control the amount of polymers or other chemicals added to the aqueous liquid.
