[Continued on next page] — (54) Title: MODIFICATION OF BENTONITE PROPERTIES FOR DRILLING FLUIDS loo (57) : Disclosed is a method for modifying bentonite to allow the bentonite to be useful in drilling mud applications. The method includes the steps of: pre- paring bentonite local to Saudi Arabia using raw water to remove contaminants from the bentonite; grinding the bentonite to a fme powder; sieving the fme powder to be between about 50 p.m and about 150 p.m in particle size to produce a sieved fme powder; mixing the sieved fine powder with polyanionic cellulose polymer to produce a modified bentonite composition; adding the modified bentonite composition to water until a homogeneous solu- tion of modified bentonite in water is formed; and allowing the homogeneous solution of modified bentonite in water to rest for about 16 hours to form a composition useful in drilling mud applications.
