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 1):
A method for cementing a subterranean well having a casing and a borehole surface, comprising:\n (i) coating the borehole surface and an outer casing surface 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 contacts the water-immiscible fluid; wherein the subterranean well has been drilled with a water-base drilling fluid.
