... configuration, and corrosive salt environment has become increasingly challenging. Thus, sealing off a salt cavern during well abandonment requires a combination of optimized placement, mechanical barriers, and fit-for-purpose surface pressure control equipment. There might be various options to permanently...

..., the cement sheath is vital to well integrity improvement. Enhanced placement techniques of conventional cements failed to prevent SCP, confirming that failure is derived from post-placement dynamic conditions. The solution must account for pressure and temperature stresses, preventing and mitigating...

Abstract In a Deepwater well off the Brazilian coast which presented a complex architecture with multiple drilling casings and liners, losses were expected during cement placement across a carbonate formation. This paper describes the use of a new real time monitoring and evaluation tool which...
