<h1>Golfinho/Atum Oil and Gas Project (Mozambique)</h1>
<p>The Golfinho/Atum Oil and Gas Project is an offshore conventional gas development in Area 1 of the Rovuma Basin,off the coast of Cabo Delgado province,Mozambique. Operated by TotalEnergies,it serves as the upstream resource base for the Mozambique LNG project,the country's first large-scale onshore LNG development. The project reached final investment decision in 2019,was suspended under force majeure in 2021 due to security conditions,and restarted onshore and offshore activities in 2026 after the consortium lifted force majeure in late 2025. First LNG is expected in 2029.</p>

<h2>Project Overview</h2>
<p>The project comprises the offshore Golfinho and Atum gas fields in Area 1 of the Rovuma Basin,developed to supply a two-train onshore LNG plant at Afungi with 13.1 million tonnes per year of liquefaction capacity. The broader Area 1 resource base contains more than 60 trillion cubic feet of gas,with approximately 18 trillion cubic feet planned for development through the first two trains. The development concept is offshore gas production tied to an onshore LNG plant,not an FPSO. The project includes subsea production,long-distance gas transfer to shore,and marine export infrastructure at Afungi.</p>
<h2>Location and Operating Area</h2>
<p>Offshore Mozambique in Area 1 of the Rovuma Basin,approximately at the coordinates -10.51,40.81. The onshore LNG plant and support infrastructure are at Afungi,near Palma in Cabo Delgado province. The Rovuma Basin is a major offshore gas province with large discoveries made in the early 2010s. The project's offshore-to-onshore configuration is central to its design: gas is produced from offshore fields,treated and liquefied at Afungi,and exported as LNG.</p>
<h2>Operator and Ownership</h2>
<p>TotalEnergies is the operator with a 26.5% participating interest. Other participants include Mitsui E&P Mozambique Area1 Ltd (20%),ENH Rovuma Área Um SA (15%),ONGC Videsh Rovuma Ltd (10%),Beas Rovuma Energy Mozambique (10%),BPRL Ventures Mozambique (10%),and PTTEP Mozambique Area 1 (8.5%). ENH Rovuma Área Um represents Mozambique's national participation through Empresa Nacional de Hidrocarbonetos.</p>

<h2>Fields,Blocks and Infrastructure</h2>
<p>The development covers the Golfinho and Atum fields in Offshore Area 1. Infrastructure includes subsea production systems,gas transfer pipeline to shore,and a two-train liquefaction plant at Afungi with capacity of 13.1 million tonnes per year. The project also includes LNG export jetty,logistics and marine facilities. Well count and detailed equipment specifications have not been published. The onshore plant at Afungi is part of a larger site with expansion capacity identified for up to 43 million tonnes per year.</p>
<h2>Production and Reserves</h2>
<p>Production has not started; first LNG is expected in 2029. Global Energy Monitor reports recoverable gas reserves of 509,706 million cubic metres (2019 data),remaining recoverable gas reserves of 450,942 million cubic metres (2021 data),and remaining recoverable crude oil and condensate reserves of 53.85 million barrels (2021 data). TotalEnergies states that Area 1 contains more than 60 trillion cubic feet of gas resources,of which 18 trillion cubic feet will be developed with the first two LNG trains. The official Mozambique LNG project site states plans based on approximately 65 trillion cubic feet of recoverable natural gas.</p>
<h2>Recent Developments</h2>
<p>TotalEnergies announced on 29 January 2026 that full project activities had restarted onshore and offshore,following the consortium's decision to lift force majeure on 7 November 2025. More than 4,000 workers were mobilized,including over 3,000 Mozambican nationals. Construction was around 40% complete,with almost all engineering and procurement of main equipment executed during the force majeure period. Reuters reported in October 2025 that project costs had risen by US$4.5 billion due to the suspension,and that TotalEnergies sought a ten-year extension of the development and production period. First LNG is expected in the first half of 2029. Remaining work will continue in a controlled access mode due to ongoing security concerns.</p>
