Objectives/background
• A major operator in Asia wanted toinvestigate why tools were unable to passthrough the Tubing Retrievable SurfaceControlled Subsurface Safety Valve(TRSCSSV)
• Suspected wire from a previous serviceprovider’s fish was lodged in the tubing,which was later confirmed following a3.75” lead impression box (LIB)deployment
• Remote, small footprint, offshoreplatforms would typically require a bargeto mobilise heavy e-line equipment
Expro Excellence
• Expro quickly mobilised a slickline SL2Kmemory camera
• The preliminary run indicated a damagedflow tube and confirmed wire was lodgedin the tubing along with a damagedTRSSSV flow tube
• During the second run to investigate theobstruction, wires surrounding the toolwere confirmed at over 1,860 meters –and subsequently using the informationto design an appropriate fishing tool
Value to client• The client is now in the process of aplanned deployment to recover the fish
