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.

[ What is claimed is:] [1.]1. A method for treating a well, comprising:combining a solid surfactant suspension with an aqueous carrier fluid to form a treatment fluid;introducing said treatment fluid into said well; andwherein said surfactant suspension comprises a solid surfactant suspended in an organic base fluid, said solid surfactant being substantially insoluble in said organic base fluid.
