摘要： Solid surfactant suspension compositions are formed by combining solid surfactants, such as alpha-olefin sulfonates, with an organic base fluid, such as diesel. Solid surfactant suspensions may be combined with an aqueous carrier fluid to form surfactant-containing fluids suitable for, among other things, forming foams or for water wetting surfaces. Solid surfactant suspensions may also be combined with additive materials, such as polymer particles, to form a dispersion or emulsion. Polymer-containing solid surfactant suspensions may also be combined with aqueous carrier fluids to form, for example, viscosified, gelled, or foamed fluids. Concentration of solid surfactant materials contained in a solid surfactant suspension may be varied to affect the function the solid surfactant suspension. For example, the solid surfactant material may function as a polymer surface wetting agent, an emulsifier, a dispersant, a viscosifier, and/or a foamer in well completion and remedial and/or workover fluids.

摘要： A preferred novel breaker-crosslinker-polymer complex and a method for using the complex in a fracturing fluid to fracture a subterranean formation that surrounds a well bore by pumping the fluid to a desired location within the well bore under sufficient pressure to fracture the surrounding subterranean formation. The complex may be maintained in a substantially non-reactive state by maintaining specific conditions of pH and temperature, until a time at which the fluid is in place in the well bore and the desired fracture is completed. Once the fracture is completed, the specific conditions at which the complex is inactive are no longer maintained. When the conditions change sufficiently, the complex becomes active and the breaker begins to catalyze polymer degradation causing the fracturing fluid to become sufficiently fluid to be pumped from the subterranean formation to the well surface.
