Abstract
Method and apparatus are provided for cementing wells and preventing fluid entry into the wellbore before the cement cures and increasing radial stress in the cured cement. Impacts or vibrations are applied to the casing during the time that the cement is curing. The source or sources of the impacts or vibration are placed in the casing during displacement of the cement slurry or soon after placement and are mechanically coupled to the inside wall of the casing. The sources may later be withdrawn from the casing or expendable sources may be used.
