In Angola, Chevron operates through a wholly owned subsidiary, Cabinda Gulf Oil Company Limited. In 2012, our Angola operations had an average daily production of 128,000 net barrels of liquids.

Exploration and Production

Chevron has an interest in four concessions: Block 0, off the coast of Cabinda province; Block 14, in deep water; Block 2, offshore northwest Angola; and the onshore Fina Sonangol Texaco area. We also have an interest in an onshore liquefied natural gas (LNG) joint venture, Angola LNG Limited.

Reaching a Major Milestone in Block 0

Chevron operates and has a 39.2 percent interest in Block 0. In 2012, the offshore concession produced its 4 billionth barrel of crude oil.

The block is divided into Areas A and B. Together they contain 21 fields that produced a net daily average of 98,000 barrels of liquids in 2012. Area A has 15 producing fields with net daily production of 60,000 barrels of crude oil and 2,000 barrels of liquefied petroleum gas (LPG). Area B has six producing fields averaging net daily production of 31,000 barrels of crude oil and condensate and 5,000 barrels of liquefied petroleum gas.

A final investment decision was announced in 2013 on the second stage of the $5.6 billion Mafumeira Field development. Plans call for a central processing facility, two wellhead platforms, approximately 75 miles (121 km) of subsea pipelines, 34 producing wells and 16 water injection wells. Platform fabrication is scheduled to begin in the third quarter of 2013, with pipeline construction scheduled to start in late 2013. First production is planned for 2015, with maximum total daily production expected to reach 110,000 barrels of crude oil and 10,000 barrels of LPG.

Work continued on the $2 billion Nemba Enhanced Secondary Recovery Stage 1 and 2 Project in 2012. Maximum total daily production is expected to be 13,000 barrels of oil-equivalent. The final stage of the project includes a new platform with compression facilities that will be connected by bridge to the existing South Nemba platform. Startup is expected in early 2015.

Front-end engineering and design at the south extension of the South N'Dola Field development continued in 2012. The development plans include a wellhead platform with production from 12 wells tied back to existing infrastructure. A capacity of 28,000 barrels of crude oil per day is planned. A final investment decision is expected in 2014.

The Greater Vanza/Longui Area (GVLA) development area is approximately 37 miles (60 km) off the western coast of Angola in Area B. The project is expected to be a key supplier of gas to Angola LNG.

The Kambala Field is approximately 5 miles (8 km) offshore Angola, in Area A. This project will further develop the Toca and Pinda reservoirs and establish production in the Vermelha reservoir.

The Lifua project is a waterflood program for the Likouala and Vermelha reservoirs in the Lifua Field. The GVLA, Kambala and Lifua projects are expected to begin front-end engineering and design in the second half of 2013.

Drilling began on a post-salt/pre-salt exploration well in Area A in late 2012 and was completed in early 2013. "Post-salt" and "pre-salt" refer to crude oil and natural gas reservoirs lying above and below different layers of salt in a geologic formation. The results are being studied. Another pre-salt exploration well in Area A is planned for the second half of 2013, along with one pre-salt and one post-salt appraisal well in Area B.

Applying Technology in Block 14

Chevron holds a 31 percent interest in and operates Block 14, a deepwater concession. In 2012, net daily production was 28,000 barrels of liquids from Benguela Belize–Lobito Tomboco, Kuito, Tombua and Landana fields.

Studies to evaluate development alternatives for the Lucapa Field, a multireservoir deepwater development on the north rim of the Congo Canyon, were completed in early 2012, and the project began front-end engineering and design that June. The development includes a floating production, storage and offloading vessel and 17 subsea wells in approximately 4,000 feet (1,219 m) of water. The facility is planned to have a design capacity of 80,000 barrels of crude oil per day. A final investment decision is expected in 2014.

Malange development concept studies continued in 2012, with front-end engineering and design expected to follow in mid-2013.

Exploration activity during 2012 focused on well planning for key prospects. New prospects were also identified, and 3-D seismic data in northern Block 14 received more study.

Block 2 and the Fina Sonangol Texaco Area

Chevron holds a 20 percent nonoperated working interest in Block 2, offshore Angola's northwest coast. Chevron also has a 16.3 percent nonoperated working interest in the onshore Fina Sonangol Texaco area. The two areas averaged a net daily production of 2,000 barrels of liquids in 2012.

Congo River Canyon Crossing Pipeline

Chevron holds a 38.1 percent interest in the pipeline, which is designed to transport up to 250 million cubic feet per day of natural gas from Angola's Blocks 0 and 14 to the Angola LNG plant in Soyo. The development plans include 87 miles (140 km) of pipeline routed under the Congo River subsea canyon. The $2 billion project began construction in early 2013 and is expected to be completed in 2014.

Angola LNG

The 5.2 million-metric-ton-per-year LNG plant in Soyo will be operated by Angola LNG Limited. Chevron holds a 36.4 percent interest in the $10 billion project. The plant is designed to process 1.1 billion cubic feet of natural gas per day, with expected average total daily sales of 670 million cubic feet of natural gas and up to 63,000 barrels of natural gas liquids. The first LNG shipment from the plant is expected in the second quarter of 2013.

Angola-Republic of the Congo Joint Development Area

Chevron is the operator of and holds a 31.3 percent interest in the Lianzi development zone, in an area shared equally by Angola and the Republic of the Congo. A final investment decision was reached on the $2 billion Lianzi Project in July 2012. The project includes four producing wells and three water-injection wells with a subsea tieback to an existing platform in Block 14. First production is anticipated in 2015. Maximum total daily production is expected to be 46,000 barrels of crude oil.
