The sector's news flow on Tuesday was dominated by portfolio upgrades and operational recoveries rather than fresh dealmaking, with a major resource upgrade at Eco Atlantic's Falklands and South Africa licences the standout story. Elsewhere, boardroom upheaval at Union Jack Oil, a production restart and dividend at Gulf Keystone, and a new gas well onstream at Savannah Energy rounded out a session of incremental but substantive updates across the space.
Navitas resource upgrade lifts Eco Atlantic's Falklands and South Africa outlook
Eco (Atlantic) Oil and Gas (AIM:ECO), the Atlantic Margins-focused explorer, has seen its strategic partner Navitas Petroleum sharply raise resource estimates across two of its most closely watched licences, the North Falkland Basin's PL001 and South Africa's Block 1 CBK. The update lands as Eco shares traded at 64.55p, down 0.91% on the day, even as the underlying resource case for its partnered assets strengthened materially.
Navitas' quarterly report, published on 24 August, put the first drilling target on PL001 at 640 million barrels of oil on a 2U prospective resource basis, of which Eco's share would run to approximately 225 million barrels in a drilling success case once its acquisition of JHI Associates completes. Navitas intends to drill a multi-target exploration well on PL001, subject to finalising its own licence acquisition, with the Sea Lion Project development campaign slated to begin in early 2027 and a success case potentially tying the target back to the existing Sea Lion platform. In South Africa, Block 1 CBK, subject to Navitas' farm-in announced in May and awaiting government approval, is now estimated to hold unrisked prospective resources of roughly 4.5 trillion cubic feet of gas and more than 3,600 million barrels of oil equivalent, based on existing seismic data, with the joint venture partners still awaiting Navitas' Section 11 application review.
"The resource estimate released by Navitas for the first drilling target on PL001 further underline the quality and potential of the asset and reinforce our decision to increase Eco's exposure to the licence," said Gil Holzman, President and chief executive of Eco Atlantic.
The upgrade validates Eco's strategy of deepening exposure to PL001 through the JHI acquisition rather than diluting its position, and gives the market a clearer read on scale ahead of both the Falklands drilling campaign and South African regulatory approvals. Neither project is yet de-risked by the drill bit, but the resource math, hundreds of millions of barrels in the Falklands and multi-trillion cubic feet of gas offshore South Africa, reframes Eco as a company whose partnered exploration inventory is larger than the market may currently be crediting, contingent on Navitas clearing its own transaction and permitting hurdles.
Union Jack Oil to "rightsize" after shareholder revolt
Union Jack Oil (AIM:UJO), the UK oil and gas junior that has more recently built exposure to US assets, has undergone a boardroom clear-out after shareholders voted at a requisitioned general meeting to remove three directors, including figurehead David Bramhill alongside Joseph O'Farrell and Zac Phillips. Shares fell 3.17% to 3.51p as the market digested the change of control.
Craig Howie and John Americanos, both former directors of the company, have been reappointed in their place, with Howie taking over as Executive Chairman and Americanos as Executive Director. The reshuffle follows a shareholder base evidently unhappy with the prior leadership's direction and cost discipline, culminating in the successful requisition vote.
Analysts at SP Angel flagged that the new board's immediate priority will be to "rightsize" Union Jack's central cost base and sharpen capital allocation at both the asset and corporate level, a mandate that signals investors expect tighter spending discipline and a more focused portfolio strategy under the returning management team.
Gulf Keystone restarts output, declares $10 million dividend
Gulf Keystone Petroleum, the Kurdistan Region of Iraq-focused operator, reported gross average production of 14,600 barrels of oil per day for the first half of 2026, down 67% from 44,100 bopd a year earlier, after a precautionary shut-in of the Shaikan Field between 28 February and 23 June, followed by a second shut-in from 19 July to 15 August. Output resumed on 16 August and is now approaching 40,000 bopd gross.
Despite the disruption, revenue based on entitlement invoices held broadly flat at $82.8 million against $83.1 million a year earlier, while adjusted EBITDA rose to $51.7 million from $41.1 million as a 25% cut in operating costs to $20.2 million offset the lost volumes. Free cash outflow narrowed to $2.0 million versus $24.6 million of free cash flow generated in the prior-year period, and the company held $63.5 million in cash and remained debt-free as of 24 August.
"Decisive action to reduce expenditures has enabled us to minimise cash outflow, maintain a robust, debt-free balance sheet and pay a $12.5 million dividend to shareholders," said Jon Harris, Chief Executive. The combination of a swift production recovery, cost discipline through the shut-ins and a maintained dividend underscores the resilience of Gulf Keystone's balance sheet even through repeated operational interruptions, reinforcing the case that Shaikan's economics remain sound once output is running.
Savannah Energy brings Uquo 13 gas well on stream in Nigeria
Savannah Energy (LSE:SAVE), the Nigerian oil and gas-focused small-cap, said its Uquo 13 well has achieved first gas and is now on stream after testing at approximately 50 million standard cubic feet per day. Shares fell 9.67% to 5.51p despite the operational progress, with the company also completing its Uquo South exploration well, where gas has been confirmed in most targeted reservoirs pending further testing to assess the discovery's resource implications.
At Stubb Creek, average gross daily production rose 29% year-on-year to 3,700 bopd across the first seven months of the year, exceeding 5,000 bopd in July alone. Cash collections climbed 13% year-on-year to $247.9 million over the same period, while revenue rose 10% to $160.6 million; trade receivables fell 22% since year-end 2025 to $394.6 million, though net debt ticked up slightly to $672.0 million from $658.8 million.
"Savannah continues to make strong progress against the nine core focus areas we set out for the business at the start of 2025," said CEO Andrew Knott. The operational gains at Uquo and Stubb Creek point to genuine production momentum, but the sharp share price fall against a backdrop of rising net debt suggests the market remains focused on balance sheet trajectory over wellhead progress.
Synergia lifts Cambay gas output on new well tie-ins
SYNERGIA ENERGY (SYN) has boosted gas production at its Cambay licence in India after completing a pipeline tie-in for three legacy wells, with further output gains expected within days. Shares fell 4.35% to 0.011p on the day.
The tie-in restores production from previously shut-in wells rather than adding new discoveries, giving Synergia an incremental but immediate lift to its Indian gas output ahead of anticipated further gains as the connected wells ramp up.
Southern Energy sales rise 4% despite field shut-ins
Southern Energy (SOUC), the Gulf Coast-focused natural gas producer, lifted second-quarter sales by 4% on stronger oil prices, even as a transportation dispute kept two fields offline. Shares traded at 3.75p.
The sales growth despite the shut-ins points to firmer realised pricing offsetting lost volumes from the affected fields, with resolution of the transportation dispute likely to determine how quickly Southern Energy can restore full production across its portfolio.
