... the necessary density and rheological properties. An error in estimating the pore pressure or fracture gradients can induce wellbore instability and lost circulation. If these losses are not controlled, during the cementing job the programmed top of cement (TOC) will not be achieved, zonal isolation...

Paper Number: SPE-202430-MS
... The WELL-A well was drilled with 9-½ in. hole to a total depth of 6,174 mMD, the 7 in. production liner run and the primary cement job attempted. Wellbore clean-up operations were completed, and a cement evaluation log performed. The well was suspended and the rig moved off. PW&C remediation...

... the ability to work down the liner and subsequently rotate throughout the cement job. This resulted in loss of rotation of the string during cement placement, with evidence of partial pack-offs. Pre-job planning clarified the impact of displacement rate on open hole dynamic pressure, and open hole...

Post drilling and upon completion of the cement job, the cementing scorecard was populated with actual job parameters based on the drilling operation report and pressure matching data from cementing contractor. An actual cementing score...

... objectives. Apart from operational success, expectations which hitherto factored in possibility of top-up jobs were exceeded; for the exploration well the critical zones were covered with good returns to seabed observed on all the cement jobs as monitored by ROV. Hard cement were tagged and drilled out from...

... yield the desired results. As a result, remedial cement squeeze jobs were needed in many primary cement jobs. To overcome these challenges, an innovative cement spacer system was engineered and applied. The environmentally preferred spacer system contains a biopolymer to mitigate lost circulation...

... shoe was achieved on the second well. Both wells used standard 12-lbm/gal slurries. The third and final well on the pad required a step-change in the cement job design to achieve cement to surface. The most successful cementing job was achieved on the third well by redesigning the slurry to a lower...

Many primary cementing jobs fail to stop interzonal communication, and poor cement bonding has been credited with the most significant cause of annular casing pressure in outer casing strings.
