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 1):
A method of cementing a subterranean well having 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 from 0.1 percent to 3 percent 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 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 acoustically coupled to the casing.
