Paper presented at the 49th U.S. Rock Mechanics/Geomechanics Symposium, June 28–July 1, 2015
Paper Number: ARMA-2015-294
... Abstract Microannuli that develop along the cement-casing interface have been identified as common leakage pathways in wellbores. We have developed an experimental system that allows laboratory testing of wellbore specimens which are comprised of a cement sheath cast on a steel casing...
