摘要： Hydrocarbon fracturing fluids are made by combining organic phosphate esters with polyvalent metal salts in hydrocarbon carriers to form gels; breaking of the gel is retarded or otherwise controlled over a wide range of water concentrations through the use of slowly soluble alkaline earth metal compounds, preferably hard burned magnesium oxide, which may be added along with the gel component. The slowly soluble alkaline earth metal compound is employed together with an oily acid breaker retarding agent such as tall oil.

摘要： A method of treating a subterranean formation comprising the steps of providing a gelled liquid hydrocarbon treatment fluid 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 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.

摘要： The invention provides (1) a method of increasing the thermal stability of an oleaginous liquid containing a high surface area silica viscosifier therein by adding a water soluble biopolymer thereto; and (2) a drilling, completion, workover, or well servicing fluid comprising an oleaginous liquid, a water soluble biopolymer, and a high surface area silica viscosifier. The method and fluid may optionally contain a low molecular weight polar additive preferably having a molecular weight less than about 400 and containing one or more polar groups per molecule selected from the group consisting of hydroxyl, amino, and mixtures to thereof.

摘要： This invention provides a water-free oil based fluid polymer suspension composition for use as a rheology modifier and fluid loss reducer in oil or gas well servicing fluids. It has been found that by using white medicinal oil as a carrier, high solids content and environmental friendly anhydrous fluidized polymer suspensions of xanthan gum, cellulose ethers, guar gum and derivaties thereof can be prepared. More specifically, in one aspect, an oil-based fluid polymer suspension (FPS) composition for use in oil or gas well servicing fluids is preferred containing: (a) a hydrophilic polymer; (b) an organophilic clay; (d) a stabilizer; and (d) a white medicinal oil having selected properties.

摘要： Well bores are drilled using an invertible oil external-water internal emulsion drilling fluid which is then inverted to a water external-oil internal emulsion by contacting it with an aqueous acid solution containing an anionic sulfonate surfactant for preventing aqueous acid solution-crude oil emulsions and crude oil sludging, and a chemical (eg an ethoxylated amine) for preventing the anionic sulfonate surfactant from rcacting with the emulsifier in the oil external-water internal emulsion.
