Rockhopper warns of Argentine pressure on Sea Lion contractors
Rockhopper Exploration (AIM:RKH) has disclosed that Navitas Petroleum, operator of the Sea Lion project in the Falklands, is moving to replace two contractors after one withdrew from the project in the wake of continued Argentine government efforts to sanction parties involved in Falkland Islands activity. The North Falkland Basin-focused explorer's shares fell 15.157% to 51.5p as the update underlined the political exposure attached to one of the UK's most closely watched offshore developments.
Navitas said the contractor's withdrawal, reported in the media, followed remarks by President Javier Milei referenced in a partnership report dated 4 September. The operator is acting to replace the two breaching contractors and will continue to make adjustments to the project as required, stressing that development continues with the full support of both the Falkland Islands Government and the UK government. Navitas said it does not currently expect a material adverse effect on the project, but flagged that the assessment could change if replacement is delayed or unsuccessful, if further contractors withdraw without suitable alternatives being found, or if Argentine government activity escalates further.
"This particular agreement has not progressed, but the work we did together has materially advanced our understanding of what an offshore compute development at Earlham would require," said Steve Brown, chief executive of Orcadian Energy.
The update lands only weeks after Rockhopper completed a $180 million share placing and open offer at 70p per share to fund its 35% pro rata share of the OSX-1 vessel acquisition, earmarked for Sea Lion's Central Development Area to lift field capacity by 125,000 barrels of oil per day. Navitas is targeting a final investment decision on that phase in the first half of 2028 and first production by the end of 2030, while Rockhopper maintains that first oil from the Northern Development Area Phase 1 remains on track for the first quarter of 2028. The episode is a reminder that Rockhopper's investment case now rests as much on Buenos Aires's political temperature as on subsurface execution, and the shares' sharp fall shows the market pricing that risk in real time even as both companies insist the project timeline is intact.
Orcadian Energy ends data centre partnership agreement on Earlham
Orcadian Energy (AIM:ORCA), trading at 17.75p, has terminated the non-exclusive joint development agreement it struck on 2 September with an American developer of offshore data centre infrastructure. The two parties agreed to part ways after a month of engagement showed the development scope and timeline for Orcadian's Earlham gas field did not align with the partner's near-term deployment priorities.
The exclusivity option attached to the September agreement was never exercised, no exclusivity fee was agreed or paid, and no amounts are payable by either side as a result of the termination. Orcadian retains all of its rights in licence P2680, which remains wholly owned by the company. The original agreement had opened a 90-day window to negotiate a definitive transaction covering the Earlham and Orwell fields, with the American partner positioned as a potential buyer of power from the proposed Earlham Gigagrid scheme, an offshore power station paired with carbon capture and a co-located data centre. "Our view of the opportunity is undiminished, and we continue to engage with a number of other potential partners," said Brown.
The clean exit, with no fees or penalties changing hands, leaves Orcadian free to shop the Gigagrid concept to other suitors without encumbrance, but it also signals that converting North Sea gas assets into power-for-compute deals is proving harder to time than the September announcement implied. The company's challenge now is converting stated ongoing interest from other parties into a definitive agreement before investor patience with the pivot wears thin.
Tower Resources secures Cameroon licence extension, pushes NJOM-3 spud to 2027
Tower Resources (AIM:TRP), the Africa-focused oil and gas explorer whose shares slipped 6.9% to 0.0135p, has extended the initial exploration period for its Thali licence by a further year, to 2 October 2027. The extension clears the way for formal approval and completion of the previously announced farm-out of a 42.5% interest in Thali to Prime Global Energies.
Tower said the farm-out has already received approval from the President of the Republic of Cameroon, conveyed through the Prime Minister's office to the Société Nationale des Hydrocarbures and MINMIDT, though it could not specify timing for the remaining procedural steps. The NJOM-3 appraisal well, targeting the Njonji structure within the Thali block, now carries a spud date in the second quarter of 2027, with Tower working to conclude a rig contract in parallel with farm-out completion. The well is designed to test both the reservoirs already encountered by previous discovery wells on the structure and additional prospective reservoirs. "We are very happy to share this long-awaited news with shareholders," said Jeremy Asher, chairman.
The extension buys Tower the time it needed to land the Prime farm-out without the licence lapsing, but the renewed timeline, with spud now pushed to 2027, underscores how long this appraisal has already taken to reach the drill-bit stage, leaving execution risk firmly on the remaining approval steps in Yaoundé.
