The surfactant is a stearate, preferably aluminum stearate, and the viscosifier is an oil compatible bentonite or polyacrylamide polymer. The resultant product is a thin pigmented solution of low viscosity. When the lubricant is dispersed in a water based drilling or completion fluid, the filming amine is attracted to and coats metal in the well. When the metal rubs against anything, such as coiled tubing rubbing against the side of the production string, a lubricious emulsion is created on the metal at locations where it is rubbing against something.
