Abstract:
A method of cementing a subterranean well to form an expanded set cement acoustically coupled to the casing. Systems for cementing a wellbore are also disclosed.

Claim (Index 20):
A method of cementing a subterranean well having a material disposed on an outer surface of a casing disposed within a borehole, comprising:\n (i) preparing a cement slurry comprising water, hydraulic cement, and an amount of an expanding agent suitable to produce expansion of the cement slurry upon hardening into an expanded set cement as determined according to API 10B-5; (ii) disposing the slurry in an annulus between a formation and the outer surface of the casing in a downhole region of the well borehole; and (iii) allowing the cement slurry to harden and expand in an amount sufficient to form an expanded set cement having a Young's modulus from about 1 to about 10 GPa, as determined by ASTM C469, which is acoustically coupled to the casing and to at least a portion of the formation; the expanding agent comprising CaO, MgO, or a combination thereof; and the amount of expanding agent present in the cement slurry being suitable to produce an amount of expansion of the cement slurry upon hardening into the expanded set cement which compresses at least a portion of a material present on the outer surface of the casing between the expanded set cement and the casing.
