Abstract:A serious problem in well cementing is the failure of bond between the cement and the fomation or the pipe. Such fai ure may allow fluid and/or gas movement from one zone to another. Also, a poor bond may result in loss of produced materials, premature reservoir depletion, and unsatisfactory stimulation operations. A means of decreasing such problems is the introduction of expansive properties to the cement system and has been recognized for some time. The addition of salts and other means have been used for this purpose. The availability of expansive cements opened a new area of investigation. This paper compares the expans ion properties of shr inkage-compensating cements with other cements. Other properties such as pumping time, compressive strength, and bonding of the cement systems were evaluated
