The Atlantic-margin frontier, read by operators.

The constraint is congestion and cadence, not discovery. With Stabroek output set to roughly double by 2027, the pressure sits on berth windows, shore-base throughput and back-haul, not on whether the barrels exist. Georgetown's main shore base, GYSBI, is already saturated and runs a separate off-port support yard to absorb the overflow, and the Vreed-en-Hoop base, operating for some years now in support of SURF and subsea work, is saturated too, with its next phase under review. A new commercial port came on stream in early 2026 but is not yet oil-and-gas capable, so the live logistics question is adding and converting capacity, not finding barrels. The Longtail gas-and-condensate pivot adds a second development profile to plan around, and across the border Suriname's two drillships from October 2026 stand up a Paramaribo supply chain that did not exist a year ago. The firms sized for first oil are not automatically sized for the second wave, or for two countries drilling at once.

Pre-FID, so the work is gateway infrastructure and appraisal logistics, not production. Capricornus moving to concept screening, with Venus and Mopane both aimed at end-2026 FIDs and first oil targeted around 2029, turns a slow question into a sequencing one: whether Lüderitz, closer to the Orange Basin acreage, and Walvis Bay as overflow can carry more than one FID-scale campaign in the same window. Walvis Bay has deepened its entrance channel to 16.5 metres and added a drilling-fluids base, but Lüderitz Phase 1, the dedicated supply base nearest the fields, is only expected to deliver capacity around 2027 and has already seen a supply-base tender pulled and its scope questioned. The bp and TotalEnergies entries into Walvis and Lüderitz widen the basin but push first marine demand on that acreage toward 2028. This is positioning done before the FID, not after it, in a window where capital is mobile and watching whether the shore side keeps pace.

A cross-border basin where the logistics question splits across two jurisdictions and two sets of port and local-content rules, so the advantage goes to whoever can read both sides at once. Supply runs largely through the Senegal Supply Base at Môle 1 of the Port of Dakar, which has served Sangomar at around 100,000 bpd and GTA on the maritime border since both came online; the open question is whether that same base and a more nationally controlled operator mix can carry Sangomar Phase 2 and a GTA expansion. The state takeover of Yakaar-Teranga signals Senegal intends to drive its own gas timeline, which changes who the logistics counterpart is and how procurement runs. With the supermajors stepping out toward Guinea-Bissau and The Gambia, the basin is entering a phase where reading the cross-border supply chain, not just the resource, decides who can deliver.

Baleine has moved from first development to phased expansion, which shifts the logistics question from standing a base up to scaling its throughput without losing the drilling cadence. Phase 3 lifts the field toward 150,000 bpd from a development about 70 km off Abidjan, and the supply network is being built out in step: the government is adding three logistics bases at Abidjan and one at San Pédro for offshore operations, alongside the operators and contractors already serving Baleine. The pressure is on base capacity and supply rhythm, not on whether the field works. With Bubale appraisal ahead and Calao behind it, the basin is building a multi-field pipeline, and phase by phase the requirement climbs faster than most plans assume.

A mature producing basin where the logistics question is sustaining brownfield infill cadence, the six-well 2026 Jubilee programme and the approved 20-well Plan of Further Development, not standing a base up. Supply runs through Takoradi, the country's established oil-and-gas hub about 60 km from the fields, which added a dedicated offshore-supply-vessel terminal in 2024 and deepened its draft, so the shore side is in place. Local-content enforcement is real here and shapes who can actually supply, so the logistics plan and the compliance plan are the same conversation. The TEN FPSO purchase and the move to extend the Jubilee and TEN licences to 2040 signal a long brownfield runway, where the read worth paying for is which suppliers qualify against the requirement, not the headline rule.

The Area 1 restart and a third FLNG tender reopen a long logistics runway against a hard security and access backdrop, where mobilisation sequencing and contractor readiness matter more than headline capacity. Almost all Area 1 logistics run through Pemba Bay, the natural-shelter hub where TotalEnergies' base at Muxara and the works at the Port of Pemba sit, with Coral Norte moving through mooring and hull toward first LNG in 2028. The binding constraint is not quay length, it is whether security in Cabo Delgado holds well enough to keep remobilisation and supply continuous, which independent observers describe as improved but not settled. This is a long-horizon basin where early positioning compounds, and where continuity of access, not capacity, is the question.
