Abstract:
Pre-stressed cementing methods involve preparing a cement slurry containing water, inorganic cement, and capsules of an expanding agent. The slurry is placed in an annular region in the well and hardened. Expansion of the set cement is delayed. Water infiltration activates the expanding agent to rupture the capsules and release the expanding agent. The expanding agent reacts to expand the set cement to a state of compression within the annular region. The state of compression can be maintained during changes in casing dimensions from temperature or pressure, mechanical disturbance, or mud contamination. The state of compression in the annular region may be monitored by acoustic impedance measurements.

Claim (Index 17):
The method according to  claim 12 , wherein the bonds between the first tubular body and the expanded set cement, and between the borehole wall and the expanded set cement or between the second tubular body and the expanded set cement are maintained after fluctuating the dimensions of the first tubular body in response to a temperature change, a pressure change, a mechanical disturbance resulting from a well intervention, or a combination thereof.
