Methods and compositions for treating subterranean formations with gelled hydrocarbon fluids

摘要

-37 Among other things, methods of treating a subterranean formation with gelled hydrocarbon fluids are provided. In certain embodiments, these methods comprise the steps of providing a gelled liquid hydrocarbon treatment fluid 5 comprising a liquid hydrocarbon and a gelling agent that comprises a polyvalent metal salt of an organophosphonic acid ester or a polyvalent metal salt of an organophosphinic acid, and treating the subterranean formation with the gelled liquid hydrocarbon treatment fluid. The gelled liquid hydrocarbon treatment fluids of the present invention are suitable for use in subterranean treatment operations, such as 10 subterranean stimulation and sand control treatments like fracturing and gravel packing, that may be carried out in subterranean formations for the production of hydrocarbons. The compositions and methods of the present invention also may be suitable, for example, to be used as plugging agents, well bore cleanup fluids, viscous sweep fluids, or insulating fluids to be used in associated methods. 10/12/08.va 17673 speci,37
