What Union Jack Oil does

Union Jack Oil plc is an AIM-listed onshore oil and gas exploration and production company headquartered in Bath, England. The company holds working interests in 13 UK onshore petroleum licences across the East Midlands, Humber Basin, and East Yorkshire, plus two Oklahoma licences acquired in 2024, encompassing producing assets (Wressle 40%, Keddington 55%, Fiskerton 20%), development projects (West Newton 16.665%, Biscathorpe 45%), and exploration prospects (North Kelsey 50%). The core technical approach relies on conventional industry methods — 3D seismic interpretation, petrographic and geochemical analysis (conducted by Applied Petroleum Technology UK), and corelab inspection — applied to de-risk drilling and appraisal targets. The most significant undeveloped asset is West Newton, where independent analysis estimates 146.4 mmbbl OIIP and 211.5 bcf GIIP base case, rated AA carbon intensity by GaffneyCline.

The business model is commodity-price-exposed hydrocarbon production sold under long-term contracts to UK refineries — primarily Phillips 66 Humber and Immingham — via road-tanker haulage. Additional revenue streams include passive mineral royalty interests in Texas and North Dakota, and periodic asset disposals/farm-outs. The company operates as a non-operator across most UK assets, partnering with Egdon Resources (operator of Wressle, Biscathorpe, Keddington, Fiskerton, North Kelsey) and Rathlin Energy (operator of West Newton), which limits capex but constrains direct operational control. Marketing and capital-raising are conducted via RNS announcements, investor presentations, broker relationships (SP Angel), and listings on AIM, OTCQB, and Aquis Market. As of April 2026 the market capitalisation was £5.86M with 152.87M ordinary shares outstanding.

The strategic situation is defined by a pending all-share takeover offer from Reabold Resources plc (received 15 June 2026), a co-investor in the West Newton project that is also exploring a 100MW 'wellhead-to-data centre' co-location development. Under UK takeover rules Reabold must announce a firm intention or withdraw by 13 July 2026. The board comprises Executive Chairman David Bramhill (43+ years natural resources experience), Executive Director Joseph O'Farrell, and Independent Non-executive Director Dr Zac Phillips. The company is non-operator, micro-cap, and presently reinvesting modest equity raises into development drilling and US diversification.

Revenue model

1. Oil and Gas Production: Union Jack Oil generates revenue from the sale of hydrocarbons produced from its UK onshore assets. Produced oil from the Wressle Oilfield is sold under existing sales contracts to Phillips 66 Humber refinery. Keddington Oilfield produces approximately 25 barrels of oil per day sold to nearby refineries. Fiskerton production is sold to the Immingham refinery. Revenue is commodity-price-exposed and production-volume-driven.
2. Mineral Royalties (USA): The company holds mineral royalty interests in Texas and North Dakota in the United States, generating passive royalty income from production on those mineral interests.
3. Asset Disposal and Farm-Outs: The company generates income through farm-out agreements and asset transactions, such as the sale of interests in the Claymore Area Royalty Agreement and periodic asset rationalisation.

Partnerships

Four partnerships are on record, tiered core and minor.

• Rathlin Energy U.K. LimitedcoreStrategic or Co-development Partner · 1 January 2013Rathlin Energy U.K. Limited is the operator of PEDL183 containing the West Newton gas discovery. Union Jack holds a 16.665% interest alongside Reabold Resources (16.665%), with Rathlin holding the remaining 66.67% and operatorship. West Newton was discovered in 2013 by the West Newton-1 well (A-1) and further appraised by A-2, B-1, and B-1Z wells. The Environment Agency issued a permit variation to Rathlin in February 2026 for reservoir stimulation and recompletion work on the WNA-2 well.
• Egdon ResourcescoreStrategic or Co-development PartnerEgdon Resources is the operator of multiple Union Jack licences: PEDL180/PEDL182 (Wressle, 40% UJO), PEDL253 (Biscathorpe, 45% UJO), PEDL005(R) (Keddington, 55% UJO), EXL294 (Fiskerton, 20% UJO), and PEDL241 (North Kelsey, 50% UJO). Egdon operates all of Union Jack's UK producing and development assets except West Newton.
• Europa Oil & Gas LimitedcoreStrategic or Co-development PartnerEuropa Oil & Gas Limited is a 30% partner in the Wressle Oilfield (PEDL180/PEDL182), alongside Union Jack Oil (40%, operator Egdon Resources) and Egdon Resources (30%). The partnership has advanced Wressle to production with cumulative net revenues exceeding US$18 million.
• Data Centre Operators (Unnamed)minorOthersReabold Resources, Union Jack's co-investor in West Newton, is actively seeking data centre partners to co-locate a facility of up to 100MW on site at the West Newton A well near Hull. The proposed project, described as Europe's first 'wellhead-to-data centre' development, would be powered directly by gas extracted from the West Newton estimated 8 billion cubic metres of reserves using mini-fracking, eliminating the need for a grid connection. Discussions with unnamed data centre firms are ongoing.
