ESCO – Frisia BAS-3O Workover 2019
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.
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
