In Angola, Chevron operates through a wholly owned subsidiary, Cabinda Gulf Oil Company Limited. In 2013, our Angola operations had an average net daily production of 119,000 barrels of liquids and 82 million cubic feet of natural gas.

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 90,000 barrels of liquids in 2013. Area A has 15 producing fields with net daily production of 54,000 barrels of crude oil and 2,000 barrels of liquefied petroleum gas. Area B has six producing fields that net an average of 29,000 barrels of crude oil and condensate and 5,000 barrels of liquefied petroleum gas per day.

Work continued on the Nemba Enhanced Secondary Recovery Stage 1 and 2 Project in 2013. The two-stage development project includes additional compression facilities on a new platform and a bridge connecting it to the existing South Nemba platform. Installation of the platform was completed in early 2014. Total daily production is expected to be 12,000 barrels of crude oil. Startup is planned for 2015.

The second stage of the $5.6 billion Mafumeira Field development, known as Mafumeira Sul, includes a central processing facility, two wellhead platforms, approximately 75 miles (121 km) of subsea pipelines, 34 producing wells and 16 water-injection wells. The facility is designed for a capacity of 150,000 barrels of liquids and 350 million cubic feet of natural gas per day. Platform fabrication began in the third quarter of 2013, and pipeline construction started later in the year. In 2014, platform and topside fabrication will continue, and pipeline construction is expected to be completed. First production is planned for 2015, ramping up to full production in 2017.

Front-end engineering and design for the South N’Dola Project, a development at the south extension of the N’Dola Field, continued through 2013. The development plans include a wellhead platform with production from 12 wells tied back to existing infrastructure. The facility is planned to have a daily capacity of 28,000 barrels of crude oil and 50 million cubic feet of natural gas. Work continues toward a final investment decision.

The Greater Longui Area development 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 for Angola LNG. The development includes a wellhead platform and a processing and compression platform in the Sanha complex. Front-end engineering and design for the project is expected to begin in the first half of 2014.

The Kambala Field is approximately five 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. Front-end engineering and design work is planned for the second half of 2014.

Exploration

Drilling of a post-salt/pre-salt exploration well in Area A was completed in early 2013, resulting in a discovery in the post-salt Vermelha level. “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. Development plans are being evaluated.

Drilling began for an appraisal well in the Minzu Field in late 2013 and is expected to be completed in the second quarter of 2014. Drilling is expected to begin for a pre-salt exploration well in Area A in the second quarter of 2014.

Applying Technology in Block 14

Chevron holds a 31 percent interest in and operates Block 14, a deepwater concession. In 2013, net daily production was 27,000 barrels of liquids from the Benguela Belize–Lobito Tomboco, Kuito, Tombua and Landana fields.

Planning continues on the Lucapa Field multireservoir deepwater development on the north rim of the Congo Canyon. Additional subsurface studies were begun in 2013 to allow for further evaluation and planning.

Front-end engineering and design work is expected to begin for the Malange Field development, a five-well subsea tieback to the existing Tombua-Landana platform, in the first half of 2014. The project is anticipated to be a significant supplier of natural gas to Angola LNG.

Exploration

In 2013, exploration activity in Block 14 focused on well planning for key prospects. Additionally, new prospects were identified and 3-D seismic data was reviewed.

Block 2 and the Fina Sonangol Texaco Area

Chevron holds a 20 percent nonoperated working interest in Block 2, offshore Angola’s northwest coast, south of the Congo River. 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 1,000 barrels of liquids in 2013.

Congo River Crossing Pipeline

Chevron holds a 38.1 percent interest in the Congo River Crossing Pipeline, which is designed to transport up to 250 million cubic feet of natural gas per day 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. Installation of the pipeline and the pipeline operation platforms for the $2 billion project was completed in 2013. Drilling operations on the pipeline well intersection under the canyon and final pipeline tie-ins are planned to begin in the second half of 2014. Commissioning and startup of the pipeline are targeted for 2015.

Angola LNG

The 5.2 million-metric-ton-per-year LNG plant in Soyo is operated by Angola LNG Limited. Chevron holds a 36.4 percent interest in the $10 billion project. The plant can 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.

This is the world’s first LNG plant supplied with associated gas, natural gas produced as a byproduct of crude oil production. Feedstock for the plant originates from multiple fields and operators. The plant produced its first LNG shipment in the second quarter of 2013. Commissioning and testing of the plant continued in 2014. Due to the variability in the associated gas that supplies Angola LNG, the plant is expected to operate at approximately 50 percent capacity until permanent plant modifications are completed in 2015. Total daily production in 2013 averaged 83 million cubic feet of natural gas (30 million net) and 2,000 barrels of natural gas liquids (1,000 net).

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. The Lianzi Project includes four producing wells and three water-injection wells with a subsea tieback to an existing platform in Block 14. The project is designed for a capacity of 46,000 barrels of crude oil per day. In 2013, detailed engineering was completed, and manufacture of subsea equipment progressed. First production is planned for 2015.
