United Oil & Gas Plc, the oil and gas company with a high-impact exploration asset in Jamaica and a development asset in the UK, has announced that it has signed a non-binding Memorandum of Understanding (MOU) with TDI Brooks International, a global leading provider of geotechnical and geochemical survey services with over 29 years' experience, to secure a specialist survey vessel for the planned piston coring and surface geochemical program on the Walton Morant License, offshore Jamaica.

Highlights:

MOU signed with TDI Brooks International to secure a vessel for Q4 2025 piston coring and surface geochemical survey
Program to collect 40–60 seabed cores across the Walton and Morant Basins, alongside bathymetric, multibeam, and heat-flow surveys
Field operations expected to last two to three weeks, with mobilization planned for Q4 2025
Execution during this window enables material cost savings, as the TDI Brooks vessel will transit via Jamaica en route from Trinidad
Critical de-risking step supporting ongoing farm-out discussions and shareholder value creation

Survey Scope and Schedule

The piston coring and surface geochemical campaign, to be undertaken by TDI Brooks International, forms a key part of United’s forward work program under its extended license to January 2028. The survey will involve the collection of 40–60 seabed core samples across the Walton and Morant Basins, accompanied by bathymetric, multibeam echo-sounding, and heat-flow surveys.

The data will be analyzed for geochemical and thermal signatures to confirm the presence of thermogenic hydrocarbons, assess source rock maturity, and refine basin modeling, materially enhancing the definition of key prospects, including Colibri and Oriole.

Following formal contract execution, which is expected to take place shortly, TDI Brooks will mobilize the vessel later this quarter. Field operations are expected to last for two to three weeks, with completion anticipated within a short operational window and initial analytical results expected in late Q4 2025 to early Q1 2026.

Brian Larkin, Chief Executive Officer of United Oil & Gas, commented: “Securing the vessel agreement with TDI Brooks is a decisive move that takes United from preparation into execution.

“The piston coring and geochemical survey will deliver vital new data to confirm the presence of hydrocarbons and materially de-risk the Walton Morant Basin. With a short operational window and high regional demand for vessels, it was essential that we move now to secure capacity.

“This program represents a pivotal value catalyst for United, and we strongly anticipate it to strengthen our technical position, accelerate farm-out discussions, and demonstrate our commitment to driving tangible shareholder value through disciplined, timely execution.”
