ABSTRACT:
Disclosed is a method to increase the bonding forces of a hydraulic cement to a subterranean pipe (such as a casing) by the addition of at least one cementitious expansive agent to increase the bulk volume of the cement plug and a latex. The method includes positioning a platform in a downhole pipe below the desired cement plug interval, positioning a plug dump bailer tool comprising a chamber for cement slurry and a valve to discharge the cement slurry on and above the platform, and discharging the cement slurry. The cement slurry includes an expansive agent and latex to increase the shear-bond between the downhole pipe and the cement plug.
