Chevron Overseas (Congo) has started oil and gas production from the Lianzi Development in offshore the Republic of Congo and Angola.

Discovered in 2004, Lianzi is located 105km offshore in 3,000ft of water and is the company’s first operated asset in the Republic of Congo.

According to the company, the project has the capacity to produce an average of 40,000 barrels of crude oil a day.

Chevron upstream executive vice-president Jay Johnson said: "We have the industry’s strongest queue of major capital projects that are expected deliver significant value and production growth."

Chevron Africa and Latin America exploration and production company president Ali Moshiri said: "As the first offshore energy development spanning national boundaries in the Central Africa region, Lianzi represents a unique cooperative approach to share offshore resources and may serve as a model for the development of similar cross-border fields between two countries."

"Appraisal drilling has found 694ft of net oil pay."

The field includes a subsea production system and a 43km electrically heated flowline system, which transports the oil to the Benguela Belize-Lobito Tomboco platform located in Angola’s Block 14.

The Lianzi Field is operated by Chevron Overseas (Congo), which holds a 15.75% interest.

Remaining partners are Cabinda Gulf Oil Company (15.5%), Total E&P Congo (26.75%), Angola Block 14 BV (10%), Eni (10%), Sonangol P&P (10%), SNPC (the Republic of Congo National Oil Company – 7.5%), and GALP (4.5%).

In a separate announcement, Chevron reported the appraisal of the Anchor discovery in the deepwater Gulf of Mexico.

Appraisal drilling started in June and recently found 694ft of net oil pay.
