United Oil & Gas Plc (UOG.L) is an independent upstream oil and gas company focused on the exploration, appraisal, development and production of hydrocarbons. The company holds interests in a development asset onshore United Kingdom comprising the Waddock Cross oil discovery within the PL090 licence located near the south coast of England; and a high-impact exploration licence offshore Jamaica known as Walton-Morant, which contains drill-ready prospects with an estimated 7 billion barrel mean unrisked prospective resource potential supported by 3D seismic data evidencing a working petroleum system. United Oil & Gas operates in the United Kingdom and Jamaica, targeting near-term growth through organic asset development and complementary mergers and acquisitions activity.
Founded in 2015 and headquartered in London, United Kingdom, the company was established by a former Tullow Oil management team with a strategy to acquire and unlock value in under-realised assets. It maintains a lean operational structure with interests spanning onshore UK development and offshore frontier exploration in the Caribbean.
In recent developments, United Oil & Gas received a default notice in January 2024 from the operator of its former Abu Sennan concession in Egypt and subsequently withdrew from the joint operating agreement to refocus its portfolio on core UK and Jamaica assets. The company secured a two-year extension to the Walton-Morant licence in early 2025, extending its validity to 31 January 2028, and recommenced farm-out discussions with multiple parties under non-disclosure agreements following a prior suspension. Additionally, United raised £0.8 million in April 2025 through an oversubscribed placing of new shares to fund the Jamaica farm-out process and advance de-risking work on the licence.
