Abstract
A viscosifier for an oil base drilling fluid of the type used in well drilling and workover procedures is shown which comprises an effective amount of a montan wax dispersed within the fluid to provide the needed viscosity and gel strength to properly suspend solids in the drilling fluid. Montan wax is dispersed in an oil base which contains as little as about 5 volume percent water. A basic material, such as lime, reacts in the water with the montan wax, and the partial saponification which results produces a thixotropic drilling fluid.
