ABSTRACT:
A treatment fluid that can be used for treating a subterranean formation penetrated by a wellbore is prepared from a primary treatment fluid component and an emulsion component mixed with the primary treatment fluid component. The emulsion component has an oil phase and an aqueous phase. The emulsion component comprising a source of insoluble silica particles and a source of calcium hydroxide, wherein the source of calcium hydroxide is present in the oil phase, and the source of insoluble silica particles are contained in the aqueous phase. The method is carried out by contacting at least a portion of the formation with the treatment fluid.
