ExxonMobil has announced this week that oil production has commenced at the Kizomba Satellites Phase 2 project in Block 15 offshore Angola.

The company says Phase 2 of this project consists of subsea tiebacks from the Kakocha and Bavuca fields to the Kizomba B FPSO, and the Mondo South fields to the Mondo FPSO. Esso Angola, the operator of the project says Mondo South was the first field to begin production, and the other two satellite fields are expected to come on line in the coming months.

The Mondo FPSO is operated via a joint venture between SBM Offshore and Sonangol.

Phase 1 of the project was to develop 18 wells and associated subsea tiebacks to the existing Kizomba A and B FPSOs.

As a result of this project, ExxonMobil says access has now been gained to 190 million barrels of oil with peak production estimated at 70,000 barrels of oil per day. The project is expected to increase total daily Block 15 production to 350,000 barrels.

One of the benefits of this project is that the subsea tiebacks to existing facilities eliminate the need for additional FPSOs.

ExxonMobil was awarded Block 15 in 1994 and, to date, has discovered a total of approximately 5 billion oil-equivalent barrels. Oil production from Block 15 to date has exceeded 1.8 billion barrels. Kizomba Satellites Phase 1 started production in 2012.

Operator Esso Angola has 40 percent interest in Block 15. Other co-venturers include BP Exploration Angola Limited, with 26.67 percent, Eni Exploration Angola BV, with 20 percent, and Statoil Angola Block 15 AS, with 13.33 percent. Sonangol is the concessionaire.
