Filed July 21, 1958, Ser. 749,637 6 Claims. 252-85) This invention relates to a method of preparing a composition suitable for use in treating oil well drilling fluids such as are employed in the rotary method of drilling. More particularly, this invention relates to the preparation of a composition useful in controlling the viscosity of oil well drilling fluids. It has been known for many years that tannin and humic acid containing materials and compositions prepared therefrom can be added to oil well drilling fluids to control certain of their physical properties including viscosity, gel strength and filtration rate. The use of mixtures of humic acid containing materials and caustic soda for treating drilling fluids was taught, for example, in an early article by H.
