This invention is based upon the finding that certain chlorosulfonated -olefin copolymers can be beneficially utilized in drilling fluids that are utilized in drilling subterreanean wells. For instance, it has been unexpectedly found that certain chlorosulfonated -olefin copolymers can be beneficially used as total or partial replacements for organoclays in oil based drilling fluids. The chlorosulfonated a-olefin copolymers that are useful in the practice of this invention are typically chlorosulfonated ethylene/octene copolymers or chlorosulfonated ethylene/butene copolymers. The utilization of chlorosulfonated -olefin copolymers in oil-based drilling fluids offers (1) long service life at high operating temperatures, (2) minimal formation damage, (3) improved filtration behavior, and (4) highly effective performance at low viscosifier levels. Additionally, the chlorosulfonated -olefin copolymers utilized in the practice of this invention are soluble in conventional drilling fluid formulations ...
