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.
