Namibia is emerging as a sought-after exploration destination due to significant oil discoveries like TotalEnergies’ Venus-1 and Shell’s Graff-1, La Rona-1, and Jonker-1. These findings confirm the presence of a functional light oil system offshore Namibia. Consequently, major oil companies and other industry participants are intensifying their drilling operations within the country.
Regarding TotalEnergies’ ultra-deepwater Venus-1X exploration well, it was spud at the beginning of December 2021, using the Maersk Voyager drillship. The Venus discovery is a light oil and associated gas field located in the Orange Basin, approximately 290 kilometers off the coast of southern Namibia, at a water depth of approximately 3,000 meters.
The well, located in Block 2913B, was drilled to a total depth of 6,296 meters and encountered a high-quality, light oil-bearing sandstone reservoir of Lower Cretaceous age. Block 2913B covers approximately 8,215 km2 offshore Namibia. TotalEnergies is the operator with a 40 percent working interest, alongside QatarEnergy (30 percent), Africa Oil’s Impact Oil and Gas (20 percent), and Namibia’s NAMCOR (10 percent).
TotalEnergies planned to embark on a multi-well drilling program offshore Namibia before the end of February 2023, targeting up to four wells, including the re-entry of the Venus-1X discovery well in Block 2913B to appraise the Venus discovery and to investigate a potential westerly extension of Venus, the Nara prospect, formerly referred to as West Venus, on Block 2912.
In line with these plans, Vantage Drilling’sTungsten Explorer drillship drilled and completed during the second quarter of 2023 the Venus-1A appraisal well located in Block 2913B and approximately 13 km to the north of the Venus-1X discovery well.
TotalEnergies’ partner, Africa Oil, explains that the Venus-1A is ready for its drill stem testing (DST) program to be carried out by Northern Ocean’s Deepsea Mira semi-submersible rig, which is managed by Odfjell Drilling. The rig is currently performing the DST work on Venus-1X, including the drilling of a sidetrack.
Prior to the end of the second quarter of 2023, the Tungsten Explorer drillship mobilized to the location of the Nara-1X exploration well, approximately 30 km to the northwest of Venus-1X in Block 2912, and is currently drilling the well with the plan to perform a DST in case of a discovery. In addition, a contingent appraisal is also on the cards, subject to a successful outcome from Nara-1X operations.
“The planned DSTs on all the wells are expected to provide important data for determining the dynamic performance of the reservoir(s) and estimating flow rates that could be achieved by the production wells. At this stage, there is no guarantee of an economically viable project,” underlines Africa Oil.
Africa Oil’s Impact, through its wholly owned subsidiary, Impact Oil and Gas Namibia, holds an 18.89 percent working interest in the adjacent Block 2912 (PEL 91), where it is also partnered with TotalEnergies (the operator with 37.78 percent interest), QatarEnergy (28.33 percent), and NAMCOR (15 percent).
