... Abstract A major cause of remedial operations from production liner cementing is not achieving isolation from reservoir to surface. Occurrences increase in wells with inclinations of approximately 90° and necessitate isolating areas close to the liner overlap because of the difficulty reaching...

... construction costs, and impairment of cement sheath quality, which may lead to deficient zonal isolation in the future and compromise well integrity in long term. Data analysis from studies developed by operators around the world show that approximately 12% of all nonproductive time accumulated in a certain...

... treatment and steam distribution during Steam-Assisted Gravity Drainage (SAGD) process. The migration from conventional cemented liner plug-and-perf techniques to packer-only stage isolation in open-hole has had a significant impact on the economics and efficiency of shale completions operations. As in-pay...

... hole completions with mechanical isolation were reviewed to have the ability to perform multiples stimulations (fracture or matrix) in one continuous and more efficient operation. Based on final reservoir data obtained during the horizontal open hole navigation and a calibrated Geomechanical model...
