NORTH AMERICA
Shell has started production from the Power Nap field in the south-central Mississippi Canyon area of the Gulf of Mexico. The three production wells, in up to 1,280 m (4,200 ft) of water, are tied back to the Olympus TLP via a 19-mi insulated flowline. At peak, they should deliver 20,000 boe/d for onward export through the Mars pipeline.
In the same area, Chevron and TotalEnergies have sanctioned the$1.6-billion, 150-MMbboe Ballymore oil and gas field development, 160 mi (260 km) southeast of New Orleans in 6,600 ft (2,000 m) water depth. This is Chevron’s first development in the Norphlet trend of the US Gulf. Three subsea wells will be tied back via a single flowline to the Chevron-operated Blind Faith FPU, producing up to 75,000 b/d. Start-up is scheduled for 2025.
Genesis Energy plans to construct a new 105-mi (1690km) pipeline in the deepwater US GoM to connect to an existing field development, and expand the capacity of the 380-mi (611-km) Cameron Highway Oil Pipeline System that extends along the outer continental shelf. This follows recent agreements to transport crude from two deepwater developments, due to come onstream late 2024 or in 2025, with combined production of 160,000 b/d.

Petrobras has started first-phase production from the Mero field in the Libra block in Brazil’s pre-salt Santos basin, over 150 km from the Rio de Janeiro coast. The FPSO Guanabara MV31, constructed by MODEC, is designed to produce 180,000 b/d of oil and 12 MMcf/d of gas, with facilities for water alternating gas (WAG) injection. Three further floaters with similar production capacity should start up on Mero between 2033 and 2025.
In the Campos basin, Petrobras and partner Equinor have brought online the first two wells of an Increased Oil Recovery (IOR) development at the Roncador field. Their combined output of 20,000 boe/d will lift production through the FPSO P62 to around 150,000 boe/d. In total, the partnership is drilling 18 wells to recover a further 160 MMbbl. Roncador produced first oil in 1999.
Petrobras and bp have proven a new deepwater oilfield in the pre-salt southern Campos basin, 230 km (143 mi) offshore Rio de Janeiro. Well 1-BRSA-138A-RJS was drilled in 1,833 m (6,014 ft) of water on the Alto de Cabo Frio central block.

Navitas Petroleum and Rockhopper Exploration have signed documents that lays the basis for a new technical and financing plan for development of the Sea Lion area in the offshore North Falkland basin. Navitas will acquire Premier Oil (operator of the associated licenses) from Harbour Energy, and will fund the majority of Rockhopper’s share of costs for Sea Lion’s initial phase via a loan, up to FID.
WEST AFRICA
New Age (African Global Energy) and its partners have moved closer to developing their gas discoveries in the Etinde permit in the Rio del Rey basin offshore Cameroon. They have decided the optimum approach would be to send wet gas from the IM wellhead platform south through pipeline infrastructure to the Bioko Island processing complex offshore Equatorial Guinea. They would also add new pipeline infrastructure to take the processed gas back to Cameroon, subject to approvals from the two governments.

Hibiscus Petroleum and Ithaca Energy are working with an alliance of Repsol Sinopec Resources UK, TechnipFMC and Petrofac on tieback options for the Marigold oil and gas field in the UK central North Sea. The favored concept involves drilling up to nine subsea wells, exporting production 16 km (10 mi) for processing at the Repsol Sinopec Resources-operated Piper B platform. At peak, Marigold would produce 40,000 b/d of oil, all exported to the Flotta terminal in Orkney.
Also in the UK sector, bp is preparing to invest up to $22.5 billion in various offshore projects over the next eight years. Some entail further development around the ETAP hub in the central UK North Sea and around the producing Clair and Schiehallion fields west of Shetland. In addition, bp plans exploration close to its North Sea hubs and electrification of assets in the central sector and Shetland area.
EASTERN EUROPE/EAST MEDITERRANEAN
ExxonMobil has agreed to sell its E&P subsidiary in Romania to Romgaz for over $1 billion. The assets include the deepwater Domino gas field discovery in the Black Sea, which the company drilled in 2012. ExxonMobil Exploration and Production Romania’s operatorship of the offshore XIX Neptun block will transfer to partner OMV Petrom.

CNOOC has brought onstream three new field developments offshore China. Two are in Bohai Bay: the Luda 5-2 oilfield north phase 1 project in Liadong Bay features one thermal recovery wellhead platform and one production platform, connected to processing facilities serving the Suizhong 36-1 oilfield. The company plans to drill 26 producers, delivering 8,200 b/d at peak in 2024. For the Kenli 6-1 oilfield 4-1 block development in southern Bohai, a new wellhead platform linked to facilities serving the Bozhong 34-9 oilfield will produce around 4,000 b/d via seven producer and five water injector wells.
In the Beibu Gulf region of the South China Sea, the Weizhou 12-8E oilfield development in 30 m water depth will eventually have six producer wells and one produced water reinjector, connected to the Weixinan oilfields complex.
AUSTRALIA
The Federal Department of Industry, Science, Energy and Resources has appointed Petrofac as outsourced operator to complete Phase 1 of decommissioning of the FPSO Northern Endeavour offshore northern Australia, following the liquidation of its owners in 2020. The vessel is moored between the Corallina and Laminaria oilfields, 550 km (342 mi) northwest of Darwin. Petrofac will disconnect it from the subsea equipment and temporarily suspend the wells. Two subsequent decommissioning phases will focus on permanent P&A, removal of subsea facilities, and remediation of the two fields.
