Abstract

1341167 Drilling wells SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 11 April 1972 [15 Feb 1972 16 March 1972] 6944/72 and 12265/72 Heading E1F A drilling fluid for a water-sensitive shale in a bore-hole comprises an aqueous solution of a partially hydrolysed polyacrylamide with a MW of more than 1,000,000 and an alkali metal halide, particularly potassium chloride. Sloughing may be prevented by the addition of bentonite and the pH of the drilling fluid may be modified e.g. by the addition of sodium silicate. A normal drilling fluid is used until the shale is reached.
