Exploration and Production

Through Chevron's principal subsidiary in Nigeria, Chevron Nigeria Limited (CNL), the company operates and holds a 40 percent interest in nine concessions under a joint-venture arrangement with the Nigerian National Petroleum Corporation (NNPC). Chevron also does business through other subsidiaries in Nigeria.

In 2014, Chevron's net daily production in Nigeria averaged 240,000 barrels of crude oil, 236 million cubic feet of natural gas and 6,000 barrels of liquefied petroleum gas.

Deep Water

Chevron has interests, ranging from 20 percent to 100 percent, in three operated and six nonoperated deepwater blocks in Nigeria.

Chevron operates the Agbami Field, which lies 70 miles (113 km) off the coast of the central Niger Delta region and spans 45,000 acres (182 sq km). Discovered in 1998, the Agbami Field is at a water depth of approximately 4,800 feet (1,463 m). Chevron has a 67.3 percent interest in the field. In 2014, net daily production averaged 134,000 barrels of crude oil and 15 million cubic feet of natural gas.

Agbami is a subsea development with wells tied back to a floating production, storage and offloading (FPSO) vessel. A 10-well Phase 2 development program is expected to offset field decline and to maintain production capacity. As of early 2015, eight of the wells were producing. The next phase, Agbami 3, is a five-well drilling program that began drilling in early 2015 and is expected to start production in 2016. Drilling is scheduled to continue through 2017.

Chevron has a 30 percent nonoperated working interest in the Usan Project, in 2,461 feet (750 m) of water, 62 miles (100 km) off the coast of the eastern Niger Delta region. Net daily production in 2014 averaged 32,000 barrels of crude oil and 3 million cubic feet of natural gas. Additional development drilling is planned through 2018.

The Aparo Field and the Bonga SW Field share a common geologic structure and are planned to be developed jointly. The structure lies in 4,300 feet (1,311 m) of water, 70 miles (113 km) off the coast of the western Niger Delta region. The proposed development plan involves subsea wells tied back to an FPSO vessel. A final investment decision is expected in 2015 or 2016.


Chevron operates and has a 95 percent interest in the Nsiko discovery in OML 140, which lies in roughly 8,000 feet (2,438 m) of water, 90 miles (145 km) off the coast of the western Niger Delta region. An exploration well at the Nsiko North prospect was drilled in the fourth quarter of 2014, and more exploration drilling is planned for 2015.

In 2014, we drilled two exploration wells and discovered crude oil in the Usan area. In 2015, the company plans to evaluate development options.

Natural Gas

Chevron is involved in natural gas projects in the western Niger Delta and Escravos areas, including the optimization of the Escravos Gas Plant (EGP), the Escravos Gas-to-Liquids (EGTL) facility and the Sonam Field Development Project.

CNL operates and holds a 40 percent interest in the EGP development. The EGP Phase 3B project is focused on eliminating routine flaring of natural gas associated with crude oil production. The project includes installation of 74 miles (119 km) of subsea pipelines and modifications to the production platforms. The project is expected to be completed in 2016.

Chevron and the NNPC developed the EGTL facility, a 33,000-barrel-per-day gas-to-liquids project designed to process 325 million cubic feet per day of natural gas from the EGP expansion. Chevron is the operator and has a 75 percent interest in the plant, which began production in mid-2014.

The Sonam Field Development is designed to use the EGP facilities to deliver 215 million cubic feet of natural gas per day to the domestic gas market and produce a total of 30,000 barrels of liquids per day. First production at the 40 percent-owned and operated project is expected in 2017.

With a 36.7 percent interest, Chevron is the largest shareholder in the West African Gas Pipeline Company Limited, which owns and operates the 421-mile (678-km) West African Gas Pipeline. The pipeline supplies customers in Benin, Ghana and Togo with Nigerian natural gas for power generation and industrial applications. It has the capacity to transport approximately 170 million cubic feet of natural gas per day.
