"On the Rocks" podcast - Episode 2: Offshore survey progress and piston coring programme

United Oil & Gas Plc ("United" or "the Company") is pleased to announce the release of the second episode of its internal On the Rocks technical podcast, providing further insight into the Company's ongoing Surface Geochemical Exploration ("SGE") programme offshore Jamaica.

This episode follows the recent completion of the Stage 1 multibeam echosounder ("MBES") survey and the commencement of heat-flow measurements and piston coring on the Walton-Morant Licence.

The episode features United's Business Technical Manager Paul Ryan and Head of Business Development Donal Meehan who discuss how the newly acquired seabed data are being integrated with existing seismic and geological datasets to refine and prioritise piston coring locations.

Topics discussed include:

·    Completion of the MBES survey and acquisition of high-resolution seabed data

·    Identification of seabed features which may indicate hydrocarbon migration

·    Integration of MBES and seismic data to refine piston coring targets

·    How piston coring is used to physically test for hydrocarbons in seabed sediments

·    The process of sample recovery and laboratory geochemical analysis

The discussion explains how the SGE programme is designed to physically test key elements of a working petroleum system offshore Jamaica. The results will form an important input into United's ongoing technical evaluation and commercial discussions relating to the Walton-Morant Licence.

The episode is available to view here:
