    摘要： A method of providing a substantially constant rheological profile of a drilling fluid over a temperature range of about 120° F. to about 40° F. includes adding a drilling fluid additive to the drilling fluid, wherein the drilling fluid additive includes the reaction product of a carboxylic acid with at least two carboxylic moieties; and a polyamine having an amine functionality of two or more. A composition, such as an oil based drilling fluid, includes the reaction product of a carboxylic acid with at least two carboxylic moieties and a polyamine having an amine functionality of two or more.

    摘要： A composition and method of fracturing a subterranean formation. The composition includes: about 0.25 wt. % to about 3.0 wt. %, based on a weight of the hydrocarbon liquid, of a mixture of phosphate esters, said esters selected from the group consisting of: monoester PO(OR1)(OH)2, PO(OR2)(OH)2; diester PO(OH)(OR1)m(OR2)2-m where m=0, 1, or 2; triester PO(OH)(OR1)n(OR2)3-n where n=0, 1, 2 or 3; and phosphoric acid H3PO4 wherein R1 and R2 each have 2 to 18 carbon atoms; and about 0.2 wt. % to about 1.0 wt. %, based on the weight of the hydrocarbon liquid, of an acidic polynuclear aluminum compound having an Al:Cl mole ratio ranging from about 1.40:1 to about 2.2:1. The composition is added to a hydrocarbon liquid to fracture the subterranean formation with this hydrocarbon liquid. The hydrocarbon liquid containing the composition exhibits a substantially constant viscosity.
