Abstract:
Expansive cements for use in cementing subterranean wells comprise water, an inorganic cement and one or more particulate materials that swell upon contact with a water immiscible fluid. The cements may further comprise a water immiscible fluid. Such cements are designed to seal microannuli arising from the presence of water immiscible fluids on casing surfaces, borehole wall surfaces or both.

Claim (Index 13):
A method for cementing a subterranean well having a casing and a borehole surface, comprising:\n (i) coating the borehole surface and an outer surface of the casing with a water immiscible fluid; (ii) providing a composition comprising water, an inorganic cement and one or more particulate materials that swell upon contact with the water immiscible fluid, wherein the composition is not an emulsion; and (iii) placing the composition into the well such that the composition is adjacent to the coated outer surface of the casing and the coated borehole surface wherein the subterranean well has been drilled with a non-aqueous drilling fluid.
