摘要： A substantially liquid gellant formed as one or more reaction products of a metal carboxylate or metal carboxylate amine salt, one or more organic acids, an ester which drives the reaction so that the reaction products are asymmetrical in structure, and a rheology modifier which preferentially interacts between the reaction products for prevent solidifying of the gellant reaction products until such time as the gellant is mixed with the fracturing fluid containing an activator after which the reaction products preferentially interact with the activator to gel the fracturing fluid. The resulting gellant is capable of gelling a hydrocarbon base fluid in less than about 30 seconds.

摘要： Anti-accretion additives utilize silicone chemistry to prevent bituminous and heavy oil materials from sticking to metals surfaces such as drill bits, drillstring, casing and the like. Organopolysiloxanes and/or copolymers thereof are added directly to an aqueous drilling fluid or are first diluted in a solvent for adding to the drilling fluid. Further, an alkyl polyalkylene oxide may also be added. If a silicone oil is used as the solvent, the anti-accretion additive has the increased functionality of minimizing the amount of bituminous or heavy oil material which is retained in the drilling fluid when returned to surface and permits removal of the bituminous or heavy oil materials with the solids using conventional solids control equipment.

摘要： A method of recovering hydrocarbon or synthetic base oils from used oil-based drilling mud utilizes acid to deactivate emulsifiers in the drilling mud for altering the emulsion stability and permitting removal of the solids contained in the drilling mud using conventional separation such as centrifugation. A surfactant is typically added to prevent water-wetting as a result of the addition of the acid. The recovered base oil contains substantially all of the deactivated emulsifiers, which can be reactivated through the addition of lime, allowing new drilling fluids to be prepared without the need to add significant amounts of emulsifier to the recycled base oil.
