GEO Exploration Ltd. increased reserves at license PEL 94 (Block 2011A) offshore NW Namibia.
Seismic mapping has delineated robust, dip and fault‑bounded structural closures. The seismic data interpretation has also highlighted direct hydrocarbon indicators in the area, including gas chimneys and flat spots, providing strong evidence for an active petroleum system, migration of hydrocarbons throughout the section and therefore increasing the chance that the leads are charged with oil.
The study identified Emerald (in the Albian) and Beryl (in the Cenomanian) sandstone leads in the eastern portion of the license. These sandstones contain 792 million bbl of unrisked gross mean prospective resources with 726 million bbl attributable to Emerald and 66 million bbl to Beryl.
These upgraded numbers lift the license‑wide unrisked gross mean prospective resources on PEL 94 to about 4.31 billion bbl, representing a 23% increase over the 3.52 billion bbl resource noted Mar. 27, 2023.
PEL 94 (Block 2011A) covers 5,798 sq km within Walvis basin in 450-1,550 m of water.
GEO is operator of PEL 94 (78%) with partners NAMCOR (17% ) and Aloe Investments Two Hundred and Two (PTY) Ltd. (5%).
