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 announce the successful completion of Stage 1 of its Surface Geochemical Exploration ("SGE") programme, comprising the multibeam echosounder ("MBES") survey, on the Walton-Morant Licence offshore Jamaica.

Highlights

� Stage 1 MBES survey phase successfully completed offshore Jamaica

� High-quality seabed bathymetry data acquired across approximately 1,189 km

� Data to support final selection of Stage 2 heat-flow and Stage 3 piston core sampling locations

� Survey vessel has recommenced offshore operations to progress the next phases of the SGE programme

Stage 1 (MBES) of the SGE programme has successfully acquired high-quality seabed bathymetry data across approximately 1,189 km on priority areas of the licence. The MBES data provide detailed definition of seabed morphology and will support the final selection of optimal locations for subsequent seabed heat-flow measurements (Stage 2) and targeted piston core sampling (Stage 3).

Following completion of the MBES phase, the survey vessel R/V Gyre returned to Kingston for equipment reconfiguration and has since departed to recommence offshore operations.

Stage 2 will comprise seabed heat-flow measurements, followed by Stage 3 targeted piston core sampling. A further update will be provided upon completion of offshore operations.

The SGE programme is designed to provide independent, basin-scale evidence of active hydrocarbon systems and will form an important input into United's ongoing technical evaluation of the Walton-Morant Licence and commercial discussions relating to the Walton-Morant Licence.

Brian Larkin, CEO of United Oil & Gas, commented:

"The successful completion of the Stage 1 MBES phase represents an important operational milestone in our Jamaica SGE programme. The quality of the bathymetry data acquired provides a robust foundation for the next stages of the survey, enabling informed selection of heat-flow and piston core locations.

As we move into Stage 2 and Stage 3, this work is designed to further de-risk the licence. We look forward to advancing offshore operations to progress through the next phase of the SGE programme."
