... was paramount for this project, section milling was selected to enable a rock-to-rock cement plug to restore 5 critical caprocks. Remediation of annular cement was complex because all production and intermediate casings were cemented to surface with 2 or 3 casings across the caprocks. Conventional methods would...

... to combat severe losses are pumping loss circulation pills, drilling under balance, and pumping cement plugs. A new and unique loss control strategy was introduced in one of the recently drilled well in this field, in which two pills of solid free spacer separated by a fiber carrier fluid were pumped...

... to the caprock area. On top of that, identifying the highest depth for a placement of cement plug will reduce on the amount of plugs to be placed, saving rig time and operational time. So far, 16 idle wells have since been permanently abandoned with the systematic approach of applying caprock restoration concept...
