Unpackaging Liberia’s Oil and Gas Exploration History, Alarming the Prospect.
By: Joe B Kamara| Sustainable Energy Campaigner |
Well, folks, it can be recalled that in 2016, close to the Liberian border with Sierra Leone, Oil was encountered in three major wells, namely: Mercury-1, Venus-1, and Jupiter-1. The lithological unit in which these discoveries were made was in a Cretaceous age stratigraphy, which Liberia shares with Sierra Leone(https://www.reuters.com/business/energy/sierra-leone-aims-be-west-africas-newest-oil-gas-exploration-frontier-2025-06-26/)
Recently, during 2012 – 2013, offshore exploration activities by giant African Petroleum through its drilling project, they encountered a net Oil Pay Volume at a depth of 32M, with a hydrocarbon stratum at a gross depth of 135M in Narina-1 (Block 9). This was indeed a breakthrough for Liberia’s Upstream Hydrocarbon Sector (https://lpra.gov.lr/exploration-history/).
Again, in 2010, Anadarko drilled another wide-cat well, encountering a huge hydrocarbon-bearing section in Montserrado-1. Another outstanding testament. Geologically, the presence of crude oil-hosting rocks, such as sandstone and dolostone, with Cretaceous-age rocks offshore the continental slope and shelf, speaks volumes for a huge commercial oil discovery. Not only that, but Liberia’s two major basins (the Harper Basin and the Liberia Basin) hold high characteristics of oil formation(https://oilprice.com/Latest-Energy-News/World-News/Liberia-Announces-Major-Offshore-Oil-Find.html).
Meanwhile, let's take a drive around the (1980s). Amoco Liberia Exploration Company was granted four offshore oil blocks for data acquisition and drilling. Of the four blocks, they drilled three wells between 1983 to 1984.
Seismic data and drill core gathered indicated again the presence of hydrocarbon.
Well, with all of this evidence of hydrocarbon presence, it is just possible, with current advancement made in technology and well-defined data interpretation equipment, a huge commercial oil discovery be made very soon. And this is everyone's prayer as a nation and that of the IOCs that have signed the 8 oil blocks, while we await more signings.
Early offshore exploration occurred between 1948-1972. During this period, the Government of Liberia awarded an exploration license to Union Carbide Petroleum Corporation, Chevron Oil Company, and Frontier International Petroleum. During their work, four blocks were drilled. The result by then shows there is no commercial volume of oil in the four blocks(https://lpra.gov.lr/exploration-history/)
To conclude, the features of Liberia’s basins and lithological characteristics, combined with its offshore stratigraphy, hold the confidence of encountering a commercial volume in this generation of experts and technological world. It is just about the work needed to arrive at the necessary output!
Thanks for following. Have a good day and a perfect weekend from my end.
