... Quality of cement is an integral part of well integrity. The change of downhole condition and post well site operation may lead to change of the stress-strain state of casingcement- formation system (CCFS) [1]. Cement sheath failure is manifested by inter zonal annular fluid movement and abnormally high...

... ABSTRACT: The role that geomechanics plays on stress, strain, and possible failure of a well must be better understood to ensure long-term well integrity and reduce the possibility of well failure. The local tectonic regime's stress-field affects not only the borehole during drilling but also...

... ABSTRACT: The state of stress in the cement of a completed well's annulus is a critical parameter in evaluating well integrity. This state of stress controls opening of permeable micro-annuli between the cement, formation rock, and/or casing as a result of the varying conditions of the well...

... integrity. In well integrity management monitoring of the well condition is quite limited, so geomechanically based well loading determination by numerical modelling of time-dependent well load-bearing behaviour could be significant in assessing the well casing as well as annulus cementation condition...

... ABSTRACT: The establishment and maintenance of well integrity to avoid leakage through wells is vital for production wells relevant for the petroleum industry, and for injection wells used for CO 2 sequestration. In our work we have experimentally investigated the thermodynamical effects...
