Recirculation System Increased Annual Oil Revenue USD 5.2 MillionIncreased gas production more than 250%
An operator in the Gulf of Mexico had a well producing 211 BOPD, 224 BWPD, and 210 Mcf/D with a gas lift system. Due to gas lift pressure limitations, the well was quickly approaching abandonment.
The reservoir and production engineers identiﬁed three key elements for a new artiﬁcial lift solution: reduction in bottomhole pressure, gas handling capabilities, and extended run life.
Baker Hughes installed the ﬁrst offshore Centrilift ESP recirculation system in a 5.5-in. inverted shroud to assist motor cooling capabilities and promote gas avoidance. Superior Performance (SP™) series pumps were used for increased efﬁciency and less horsepower consumption. A GCS drive allowed the bottomhole pressure to be increased or lowered, depending on the needs of the well. Also, a hydraulic workover unit was used to reduce workover costs up to 80%. With this new recirculation system from Baker Hughes, gas production jumped from 210 Mcf/D to 538 Mcf/D, an increase of more than 250%. The operator also increased daily oil revenue USD 14,490 at USD 90 per barrel. Annualized, this resulted in a revenue increase of more than USD 5.2 million.
