Commencement of MBES Operations - Walton Morant Licence, Jamaica

 

United Oil & Gas Plc (AIM: UOG) is pleased to announce the commencement of
Stage 1 of its planned Surface Geochemical Exploration ("SGE") programme on
the Walton Morant Licence, offshore Jamaica, with Multibeam Echosounder
("MBES") operations now underway.

 

Highlights

 

·      Stage 1 MBES operations commenced on the Walton Morant Licence,
offshore Jamaica

·     High-resolution seabed imaging underway to refine targets for
subsequent heat flow measurements (Stage 2) and piston coring (Stage 3)

·      Staged SGE programme designed to deliver progressive updates as
operations advance

·     Initial geochemical results from the piston coring are expected to
begin returning from approximately one month after completion of the offshore
survey

·     Programme designed to confirm the presence of a working offshore
petroleum system and support ongoing farm-out discussions

 

Operations are being conducted using the R/V Gyre, operated by TDI Brooks
International. Stage 1 of the SGE programme comprises a high-resolution MBES
survey, which will provide high-resolution seabed mapping and depth
information across priority areas of the licence.

 

The Stage 2 heat flow measurements will proceed after completion of the MBES.
Concurrently, the MBES data will be reviewed and used to refine and confirm
the final locations for Stage3 piston coring, ahead of core acquisition.

 

Upon completion and review of the Stage 1 MBES data acquisition, the Company
expects to provide an update to the market summarising the key observations
from the survey and outlining the commencement of Stage 2 and Stage 3 of the
operations.

 

The offshore SGE operations are currently expected to be completed by
mid-February, following which piston core samples recovered during Stage 3
will be shipped to TDI Brooks' laboratory in the United States for detailed
geochemical analysis. The initial results are expected to begin returning from
approximately one month post completion of the offshore survey.

Surface Geochemical Exploration Programme

 

The SGE programme is designed to test for the presence of thermogenic
hydrocarbons in seabed sediments at certain locations within the Walton Morant
Licence area. The scope and design of the SGE programme have been informed by
engagement with potential industry partners and feedback received during data
room discussions, with the objective of further strengthening and validating
the existing technical interpretation of the licence.

 

Positive results, where thermogenic hydrocarbons are identified geochemical
analysis of piston cores, would provide confirmation of the presence of a
working petroleum system offshore and materially de-risk the prospectivity
identified to date. This would further support UOG's technical evaluation and
ongoing farm-out discussions.

 

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

 

"The commencement of MBES operations on the Walton Morant Licence marks an
important step forward in offshore Jamaica. This initial phase will refine
seabed imaging and allow us to precisely target subsequent piston coring
locations.

The data and samples gathered during this programme are intended to provide
confirmation of a working petroleum system offshore and materially de-risk the
prospectivity identified to date. This is a key part of our strategy to
continue to technically de-risk this exciting exploration licence and progress
the project toward a potential farm-out, and we look forward to updating the
market after completion of Stage 1 and Stage 3, and as initial results begin
to emerge."
