SGE Survey Analysis Update
United Oil & Gas Plc (AIM: UOG), the oil and gas company with a high-impact exploration asset in Jamaica and a development asset in the UK, is pleased to provide an update on the analysis of piston core samples from its recently completed Seabed Geochemical Exploration ("SGE") survey over the Walton-Morant Licence offshore Jamaica.
United has undertaken a geochemical analysis on the 42 piston cores acquired across the Walton-Morant Licence. The analysis has identified C4 and C5 hydrocarbons, including butanes and pentanes, in select piston cores within the headspace gas dataset. United note that these higher order hydrocarbons are not typically associated with biogenic gas systems and are therefore consistent with a potential thermogenic contribution.
There is an established body of evidence for an active petroleum system in Jamaica in general, and on the licence in particular, including repeat satellite slick anomalies, thermogenic hydrocarbon geochemistry from existing onshore and offshore wells, onshore and offshore oil seeps, and onshore surface outcrops. Furthermore, petroleum systems modelling suggests the presence of oil-mature source rocks. The 2026 SGE survey is the first on the licence to be optimally positioned using 3D seismic, multibeam echosounder (MBES) seabed mapping, and satellite-derived slick anomaly data. Taken together, the data are interpreted as consistent with an active petroleum system offshore Jamaica.
United will integrate the results into its geological understanding and risking models, and the dataset will support ongoing technical evaluation and farm-out discussions.
Brian Larkin, CEO of United Oil & Gas, commented:
"The 2026 piston core survey results represent an important step forward in our understanding of the Walton Morant licence. We have identified butane and pentane hydrocarbons in the analysis. These results enhance our understanding of the licence and provide an important input as we advance towards a drilling decision. We look forward to integrating the results into our subsurface work and continuing to progress discussions with interested parties. We believe United's technical evaluation of the licence's potential will support our ongoing farm-out process as we work to advance this world-class licence which contains approximately 7 billion of prospective resources."
