Role of WEP: | IPM, engineering, procurement and execution of works |
Challenges: | During project changing well conditions, resulting in large scope changes. Technical challenging snubbing operations, large size strings handled under >200bar WHP. Combined operations snubbing and coil tubing. |
New technology: | BHGE DECT cutter on 9 5/8” casing |
Project Description
The project objective started with a reconfiguring of the leaching strings, regular workover operations. During the engineering (pre-operations) the downhole conditions changed and a repair of the last cemented casing seemed to be required. During execution additional information gathered showed that the repair was no longer a valid option. The cavern was plugged, in preparation for full abandonment the well.
