Patent ID: 7617870

Claim:
A method of cementing in a subterranean formation comprising: providing an extended cement composition consisting essentially of: cement, water, an oil-swellable particle, and a set retarding additive, wherein the extended cement composition is unfoamed and capable of remaining at a viscosity of less than 70 Bc at room temperature for at least about 1 day; storing the extended cement composition for a period of time; adding a cement set accelerator to the extended cement composition; introducing the extended cement composition into the subterranean formation; allowing the extended cement composition to set in the subterranean formation; and allowing the oil-swellable particle in the set cement composition to contact oil whereby the oil-swellable particle swells to counteract either a crack that forms in the set cement composition or a micro-annulus between the set cement composition and either a pipe string or the subterranean formation.
