a shared vision

Chevron is the operator of and holds a 31.3 percent interest in the Lianzi Unitization Zone, located in an area shared equally by Angola and the Republic of Congo.

Located 65 miles (105 km) offshore in approximately 3,000 feet (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 field, discovered in 2004, includes a subsea production system and a 27 mile (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.

The Lianzi Project is reflected in the production totals in Angola (Block 14) and in the Republic of Congo.
