Customer challenges
- A major operator in Asia wanted to investigate why tools were unable to pass through the Tubing Retrievable Surface Controlled Subsurface Safety Valve (TRSCSSV)
- Suspected wire from a previous service provider's fish was lodged in the tubing, which was later confirmed following a 3.75" lead impression box (LIB) deployment
- Remote, small footprint, offshore platforms would typically require a barge to mobilise heavy e-line equipment
Expro Excellence
- Expro quickly mobilised a slickline SL2K memory camera
- The preliminary run indicated a damaged flow tube and confirmed wire was lodged in the tubing along with a damaged TRSCSSV flow tube
- During the second run to investigate the obstruction, wires surrounding the tool were confirmed at over 1,860 meters - and subsequently using the information to design an appropriate fishing tool
Value to client
- The client is now in the process of a planned deployment to recover the fish
