Tubing Straddle System to Restore Oil Production Using Digital Slickline Conveyance: A Case Study

The mature Great Burgan Field comprises more than 2,000 wells to date, many of which utilize artificial lift in their production to maintain production targets. Tubing leaks and integrity issues pose major challenges to the artificial lift pump; these leaks eventually cause pump temperatures to exceed the operating limit, trip, and stop production.

The waiting time for a workover rig is about four months; this converts to a significant loss of oil production in every well with tubing integrity issues.

To reach and sustain the production target, rigless tubing repair is perceived as a viable quick solution to maintain production until a workover rig becomes available.
