Subsea 7 today announced the award of a substantial (between USD 150 million and USD 300 million) contract by Cabinda Gulf Oil Company Limited (CABGOC). The contract is for the Sanha Lean Gas Connection (SLGC) project comprising the construction and installation of the Lean Gas Platform (LGP) system in Block-0 offshore Angola, at a water depth of approximately 70 metres.

Project management and engineering will be performed from Subsea 7’s offices in Paris and Lisbon. Fabrication will take place at Sonamet’s yard in Lobito, Angola from 2021 to 2022, while offshore operations will occur from 2022 and 2023.

Gilles Lafaye, Senior Vice President Africa, Middle East and Caspian Region says: 
"We are delighted to have been awarded this contract by CABGOC, following a public tender. This is the result of a long-term collaboration with the client and a track record of delivering successful projects. The project reinforces Subsea 7’s presence in Angola and our commitment to support Africa’s energy industry”.

Cabinda Gulf Oil Company Limited (CABGOC)

Chevron has been in Angola since the 1930s, when Texaco products were first marketed there.

Today, through their wholly owned subsidiary, Cabinda Gulf Oil Company Limited (CABGOC), the company have an operated interest in two concessions: Block 0, off the coast of Cabinda province, and Block 14, in deep water. Chevron also have a non-operated interest in an onshore joint venture, Angola LNG Limited, a 5.2 million-metric-ton-per-year plant in Soyo.

Exploration and production activities began in 1954 when CABGOC conducted its first geological field survey. Four years later, the first onshore well was drilled at Ponta Vermelha. In 1966, the company's first offshore discovery was made in the Malongo Field, followed by first oil in 1968. The Takula Field was later discovered in 1971, and in 1975, oil was found in Block 2 of the Essungo Field.

In 1986, additional exploration by Chevron coincided with the delineation of Angola’s Block 0. To maintain optimal pressure during production, the company began using water-injection technology at the Takula Field in 1990.

In 1997, Chevron announced the discovery of the Kuito Field, the first of a series of major oil finds in the Block 14 concession. Two years later, Kuito became Angola’s first producing deepwater field.

In 2000, Texaco began engineering work on Angola LNG, the country’s first liquefied natural gas (LNG) project and the world’s first LNG plant supplied with associated gas (natural gas produced as a byproduct of crude oil production).

In 2015, Chevron reached an impressive milestone in Angola: 5 billion barrels produced from Blocks 0 and 14. More than a billion of that production came from the Takula Field.

In 2016, Chevron completed the Congo River Canyon Crossing Pipeline, and restarted then resumed shipments from the Angola LNG plant, which produced its first shipment of liquefied natural gas in 2013.

In early 2017, the main production facility of the second stage of the Mafumeira Field development was brought on line and gas export to Angola LNG began in mid-2017.

In 2018, six new wells were drilled in Mafumeira Sul and ramp-up continued at the main production facility with a total daily production averaging 52,000 barrels of liquids and 147 million cubic feet of natural gas exported to the Angola LNG plant.
