One-Trip TCP and ESP Completion Maximized Production and Efficiency

Increased 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).
