In addition to the details previously provided, some interesting insights from Envoi, agent for United Oil and Gas, follow:
- Only 11 exploration wells have ever been drilled in the entire country (comprising an area of around 258,137 km2 including all the offshore areas), all between 1955 and 1982
- Hydrocarbon shows were observed in all but one of these wells despite not having tested valid structures, as is evident on the latest data
- Just 2 of the 11 wells were drilled offshore
- Extensive onshore fieldwork and seep analysis studies have confirmed mature Eocene and Cretaceous oil-prone source rock potential, with migrated oil identified in onshore wells and outcrop samples. These include Late Cretaceous (Cenomanian-Turonian) aged organic shales exhibiting total organic carbon (TOC) up to 8% with maturity.
- Modelling also suggests significant oil potential exists in mature Cretaceous source kitchens in both the Walton and Morant basins while shallower Palaeogene shales with TOCs up to 15% could also locally be deep enough to be mature.
- An independent Prospective Resources Audit completed by Gaffney Cline & Associates in December 2020 estimates that just 11 of the total 21 prospects & leads defined to date contain a combined total unrisked mean prospective recoverable resources in excess of 2.4 Billion STOOIP (stock-tank oil initially in place). Of this, 406 MMbbls is attributable to the Colibri Prospect alone, with an upside of 966 MMbbls STOOIP.
- United is offering a material interest and potential operatorship to suitably qualified parties in the license in return for a commitment to fund a well to test the Colibri Prospect before January 2026, which would fulfill the obligations for the current Second Exploration Period of the Licence.
