... are prevented from flowing into the casing annuli and potentially to the surface. The exception being for the production flow path. Such isolation is part of well integrity ( NORSOK, 2004 ). Any event/incident that damages the sealability of cement or causes downhole fluids to flow to the surface behind casing...

... Abstract Objectives/Scope Well integrity monitoring is one of the critical processes in oil and gas wells to prevent unintended fluid movement or loss of containment to the environment. In this case study, there was continuous gas leakage to surface at high pressure through annulus "B...

... Abstract Well integrity was and continues to be a significant priority for many operating companies around the world. A compromise in well integrity may have direct impacts on production sustainability well life and the environment. Well integrity became an important topic in the last decade...
