Gelled liquid hydrocarbon treatment fluids having reduced phosphorus volatility and their associated methods of use and preparation

摘要

This invention relates to reduced volatility gelled liquid hydrocarbon treatment fluids and methods of their use and preparation. In one embodiment, this invention provides a method of treating a portion of a subterranean formation comprising: providing a reduced volatility gelled liquid hydrocarbon treatment fluid that comprises a liquid hydrocarbon and a gelling agent that comprises a polyvalent metal salt of a phosphoric acid ester, and treating the portion of the subterranean formation with the reduced volatility gelled liquid hydrocarbon treatment fluid. In another embodiment, this invention provides a gelled liquid hydrocarbon treatment fluid: that comprises a liquid hydrocarbon and a gelling agent that comprises a polyvalent metal salt of a phosphoric acid ester; that has a concentration of less than about 250 mg/liter of trialkyl phosphate esters that have a molecular weight of less than about 350; and that has a diester-to-monoester content molar ratio of at least about 2:1.
