<h1>Greater Plutonio Oil and Gas Project (Angola)</h1>
<p>Greater Plutonio is an offshore conventional oil and gas project in Angola,operated by Azule Energy Holdings. The project is located in Block 18,offshore Angola,in deep water approximately 140–160 km from Luanda. Discovered in 1999,the development was approved in 2004 and began production in October 2007. It was the first BP-operated production asset in Angola before becoming part of Azule Energy,the BP and Eni joint venture.</p>
<p>The original development comprised five fields—Galio,Cromio,Cobalto,Paladio,and Plutonio—tied back to a floating production,storage,and offloading (FPSO) vessel. A later satellite field,Platina,was added as a subsea tie-back in 2021. The project is a deepwater hub development typical of Angola’s offshore model: subsea wells connected by flowlines to an FPSO with tanker export.</p>

<h2>Location and Operating Area</h2>
<p>Greater Plutonio is located in Block 18,offshore Angola,in water depths of approximately 1,250–1,500 metres. The project area lies roughly 140–160 km from Luanda. Block 18 was awarded for exploration in the 1990s and became a significant deepwater producing block after multiple discoveries. No specific basin is consistently named in project sources; the asset is defined by its block and offshore setting.</p>
<h2>Operator and Ownership</h2>
<p>The project is operated by Azule Energy Holdings,the Angola-focused joint venture formed by BP and Eni. Ownership comprises BP PLC (46%),Sinopec International (37%),and Sonangol Pesquisa e Produção SA (16%). The involvement of Sonangol reflects the state’s upstream participation framework. BP and Sinopec interests represent the international capital and technical expertise historically active in Angola’s deepwater sector.</p>

<p>Exploration success in Block 18 led to the discovery of multiple accumulations,with the original Greater Plutonio development covering the Galio,Cromio,Cobalto,Paladio,and Plutonio fields. The project was executed as a deepwater subsea-to-FPSO development. Later,the Platina field was brought online in November 2021 as a subsea tie-back to the existing FPSO. Infill work under the Block 18 Infills programme and the Greater Plutonio Phase 5 project continues.</p>
<h2>Infrastructure and Facilities</h2>
<p>The central facility is the Greater Plutonio FPSO,a spread-moored vessel approximately 310 metres long with oil storage capacity of about 1.77 million barrels and processing capacity of up to 240,000 barrels of oil per day. The subsea system originally connected approximately 43 subsea wells via roughly 130 km of infield flowlines. Later developments added subsea equipment for the Platina tie-back and the Block 18 Infills programme,which includes subsea trees,manifolds,flowlines,and umbilicals. No LNG trains or fixed platforms are part of the development.</p>
<h2>Production and Reserves</h2>
<p>The project has been in production since 2007. Global Energy Monitor reports hydrocarbon production of 15.64 million barrels of oil equivalent (boe) in 2023,oil production of 9.85 million barrels in 2021,and gas production of 412 million cubic metres in 2021. Reported oil reserves are 105.91 million barrels (2021 data year) and remaining gas reserves of 928.26 million cubic metres (2021 data year). The original fields were estimated to contain about 750 million barrels of reserves. Recent infill activity,including the Greater Plutonio Phase 5 programme (four wells,two expected in 2025 and two in 2026),aims to sustain production.</p>
<h2>Recent Developments</h2>
<p>In June 2023,TechnipFMC was awarded a contract by Azule Energy to supply subsea production systems for the Block 18 Infills development,including subsea trees,manifolds,and flowlines. In 2024,Aker Solutions announced work linked to the Greater Plutonio FPSO. Azule Energy’s 2024 financial statements identified the Greater Plutonio Phase 5 infill drilling programme of four wells. Reuters reported in September 2025 that Azule Energy planned to invest US$5 billion in Angola over four to five years,encompassing new and existing projects.</p>
