In Angola, Chevron operates through its wholly owned subsidiary Cabinda Gulf Oil Company Limited. In 2014, our Angola operations had an average net daily production of 121,000 barrels of oil-equivalent per day, or 114,000 barrels of liquids and 78 million cubic feet of natural gas.
Exploration and Production
Chevron has an interest in three concessions: Block 0, off the coast of Cabinda Province; Block 14, in deep water; and the onshore Fina Sonangol Texaco area. We also have an interest in an onshore liquefied natural gas (LNG) joint venture, Angola LNG Limited. Chevron’s interest in Block 2 expired in July 2014.
Passing 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 87,000 barrels of liquids in 2014. Area A consists of 15 producing fields with net daily production of 53,000 barrels of crude oil and 2,000 barrels of liquefied petroleum gas. Area B has six fields that produced a net average of 28,000 barrels of crude oil and condensate and 4,000 barrels of liquefied petroleum gas per day in 2014.
Work continued on the Nemba Enhanced Secondary Recovery Stage 1 and 2 Project in 2014. The two-stage development project includes additional compression facilities on a new platform and a bridge connecting it to the existing South Nemba platform. The project was started up in early 2015. Total daily production is expected to be 9,000 barrels of crude oil.
The second stage of the 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 and topsides fabrication continued in 2014. In the first half of 2015, offshore facilities are expected to be installed and pipeline construction is expected to be finished. First production is planned for 2016, ramping up to full production in 2017.
The Greater Longui Area development is approximately 37 miles (60 km) off the western coast of Angola in Area B. Plans call for a two-platform hub, a wellhead platform for 18 planned wells in the Longui Field and a gathering platform adjacent to the existing Sanha complex. The project is expected to enable development of the Longui Field and several future developments from other Area B crude oil fields and to supply gas to Angola LNG. Timing for the project is being reviewed.
Potential future projects in Block 0 include development of the Lifua Field and the Kambala Field, as well as the southern area of the N’Dola Field.
In 2014, the company drilled one post-salt appraisal well in Area B and one pre-salt exploration well in Area A. Drilling was completed in early 2015, and the results for both wells are being evaluated. Plans call for another exploration well in Area A in the fourth quarter of 2015. “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.
Applying Technology in Block 14
Chevron operates and holds a 31 percent in a production-sharing contract for deepwater Block 14. In 2014, net daily production was 25,000 barrels of liquids from the Benguela Belize–Lobito Tomboco, Belize North, Benguela North, Tombua and Landana fields.
Potential future projects in Block 14 include development of the Lucapa Field and the Malange Field.
In 2014, exploration in Block 14 focused on well planning, the identification of new prospects and the reprocessing of 3-D seismic data.
Block 2 and the Fina Sonangol Texaco Area
Chevron has a 16.3 percent nonoperated working interest in the onshore Fina Sonangol Texaco (FST) area. Production ceased in Block 2 and in the FST area in April and July 2014, respectively. The two areas averaged a net daily production of 1,000 barrels of liquids in 2014.
Congo River Canyon Crossing Pipeline
Chevron holds a 38.1 percent interest in the Congo River Canyon 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. Drilling operations on the pipeline well intersection under the subsea canyon began in early 2015, with completion expected in mid-2015. Commissioning of the pipeline is expected in the second half of 2015.
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 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 2013. In April 2014, the plant experienced a failure resulting in an extended plant shutdown. A number of design issues have been identified that require modifications. Capacity and reliability enhancements are planned to be completed during the shutdown. The plant will be restarted following completion of these modifications and repairs, and LNG production is expected to resume in late 2015. Total daily production in 2014 averaged 75 million cubic feet of natural gas (27 million net) and 3,000 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 Unitization Zone, which is in an area shared equally by Angola and Republic of the Congo. The Lianzi Project includes four producing wells and three water-injection wells with a subsea tieback to the Benguela Belize–Lobito Tomboco platform in Block 14. The project is designed for a capacity of 46,000 barrels of crude oil per day. In 2014, engineering and procurement of materials and supplies was completed, and fabrication, installation and drilling activities began. First production is planned for the fourth quarter of 2015.
