One-Trip TCP and ESP Completion Maximized Production and EfﬁciencyIncreased oil production in Ecuador wells by 35%
A customer needed to complete two onshore wells in a mature ﬁeld in Ecuador. This operator typically performed the perforating operation before running the electrical submersible pump (ESP) completion, using kill-weight ﬂuids for well control while the completion equipment was installed. However, production testing indicated that productivity of the initial completions was reduced as result of formation damage caused by the kill weight ﬂuids used after perforating.
Baker Hughes offered a solution that combined running underbalanced tubing conveyed perforating (TCP) and the ESP in one operation. This eliminated the need for damaging well control ﬂuids, resulting in zero to minimum formation damage. This solution reduced rig time by eliminating one pipe trip, cutting three days off rig time and resulting in a savings of USD 21,000 (three days at USD 7,000 per day).
