The Lianzi extraction area
Chevron Corporation announced today that its subsidiary, Chevron Overseas (Congo) Limited, has commenced oil and gas production from the Lianzi Field, located in a unitized offshore zone between the Republic of Congo and the Republic of Angola.
Located 105 km offshore in approximately 900 meters of water, Lianzi is Chevron’s first operated asset in the Republic of Congo and the first cross-border oil development project offshore Central Africa. The project is expected to produce an average of 40,000 barrels of crude oil per day.
The field, discovered in 2004, includes a subsea production system and a 43 km electrically heated flowline system, the first of its kind at this water depth. The system transports the oil from the field to the Benguela Belize–Lobito Tomboco platform in Angola’s Block 14 and utilizes a Direct Electrical Heating (DEH) system to ensure fluid flow under a wide range of conditions.
Chevron Overseas (Congo) Limited is operator of the Lianzi Field and has a 15.75 percent interest, along with its affiliate Cabinda Gulf Oil Company Limited (15.5 percent), Total E&P Congo (26.75 percent), Angola Block 14 BV (10 percent), Eni (10 percent), Sonangol P&P (10 percent), SNPC (the Republic of Congo National Oil Company – 7.5 percent), and GALP (4.5 percent).
