Exploration and Production
In 2013, Chevron’s net daily production in Nigeria averaged 233,000 barrels of crude oil, 182 million cubic feet of natural gas and 5,000 barrels of liquefied petroleum gas.
Through our principal subsidiary in Nigeria, Chevron Nigeria Limited (CNL), we operate and hold a 40 percent interest in 13 concessions under a joint-venture arrangement with the Nigerian National Petroleum Corporation (NNPC). Chevron also does business through other subsidiaries in Nigeria.
Onshore and Near Offshore
Work to rebuild the Olero Creek production facilities and lay a new pipeline to transport natural gas from Abiteye to the processing facilities at Escravos was completed in 2012. Startup occurred in the first quarter of 2013. The production facilities were designed for a capacity of 48,000 barrels of crude oil per day.
The Dibi Long-Term Project is designed to rebuild the Dibi facilities that were vandalized in 2003 and replace the existing Early Production System facility, placed in service in 2007. The facilities have a maximum production capacity of 70,000 barrels of crude oil per day. A final investment decision was reached in the first quarter of 2013, and startup is expected in 2016.
Chevron has interests, ranging from 18 percent to 100 percent, in three operated and six nonoperated deepwater blocks in offshore 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.
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. Drilling, which started in 2012, is expected to continue through 2015. As of early 2014, four of the wells are producing. The next phase, Agbami 3, is a five-well drilling program that began front-end engineering and design work in early 2014, with a final investment decision expected in the second half of the year. 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 2013 averaged 28,000 barrels of crude oil and 3 million cubic feet of natural gas. Additional development drilling is planned through 2017.
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. Front-end engineering and design work began in the second quarter of 2013, and a final investment decision is expected in late 2014.
Our shallow-water exploration activities to identify and evaluate potential deep hydrocarbon targets are ongoing. Reprocessing of 3-D seismic data over Oil Mining Lease (OML) 49 and regional mapping activities over OML 86 and OML 88 continued in 2013.
In deep water, Chevron owns and operates OML 132, where an exploration well at Aparo North is planned for 2014. Chevron operates and has a 95 percent interest in the Nsiko discovery in OML 140. Additional exploration is planned for 2014 at this discovery, 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.
Chevron is involved in natural gas projects in the western Niger Delta and Escravos areas, including the expansion of the Escravos Gas Plant (EGP), construction of 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 are developing the EGTL facility, a $10 billion 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 is scheduled for startup in the first half of 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 2016.
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.
The Ohaji South Field, in OML 53, is planned to be developed jointly with the third-party-owned Assa-North Field. Chevron holds a 20 percent nonoperated working interest in this project, which is planned to supply natural gas for the domestic market. The company is evaluating this asset for possible divestment.
Chevron operates and holds a 40 percent interest in the Agura Independent Power Plant project. Phase 1 of the development project has a design capacity of 330 megawatts. A final investment decision is pending conclusion of commercial agreements and renewal of offshore leases.
