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

Abstract

The mature Great Burgan field comprises of more than 2000 wells to date, many of these wells utilize artificial lift in their production to maintain production targets. Tubing leaks and integrity issues pose major challenge to the artificial lift pump; these leaks eventually cause pumps temperatures to exceed the operating limit, trip and stop production. The waiting time for a workover rig is about 4 months, this converts to a significant loss of oil production in every well with tubing integrity issue. To reach and sustain the production target, rigless tubing repair is perceived as a viable quick solution to maintain production until workover rig becomes available.
