Abstract

604,007. Well drilling fluid. DEHN, S. G. (National Lead Co.). Nov. 20, 1945, No. 31229. [Class 85] In a well drilling fluid, a thin boiling starch, prepared by the treatment of starch with oxydizing agents or acids, is added to the fluid in sufficient quantities so that a water seal of low water loss is formed. The starch may form part of a dry powder mixture, including a water dispersible solid such as clay or bentonite.
