ABSTRACT:
Water-based, clay-free drilling fluids for use in drilling bore holes into subterranean formations having an aqueous mixture therein comprising water and an aluminum hydroxide agent. The aqueous phase of the drilling fluids has the aluminum hydroxide agent therein in an amount sufficient to impart non-Newtonian, pseudoplastic properties to the fluids when the fluids have a pH of at least about 8. The present invention further relates to an improved process of drilling bore holes into subterranean formations using the subject drilling fluids.
