摘要：Disclosed herein are drilling fluid compositions, and methods of producing andusing such compositions, wherein the drilling fluid compositions include a non-aqueousbase fluid, a blend of one or more copolymers, and polyethylene. The blend ofcopolymers has an average molecular weight of about 20,000 or greater, and can beprepared by reacting at least one alpha-olefin, and at least one anhydride of an
alpha,beta-ethylenically unsaturated carboxylic acid. The non-aqueous base fluid is an oil-based invert emulsion. The polyethylene has a melt index of less than about 10, and theaverage particle size of the polyethylene is about 0.06 inches or less.
