Petroleum exploration licence PEL 93, in the onshore Owambo basin in northern Namibia, is moving closer to a drilling decision. The partnership holding the licence has submitted an application to enter a new two-year exploration period starting on October 3, 2026, with a programme including preparation and drilling of at least one well.
The proposal follows the integration of around 6,000 line-kilometres of airborne gravity, magnetic and radiometric data. The analysis confirmed Prospect 9 as the priority target, according to 88 Energy, which holds a 20% interest in the licence. The stage nevertheless remains administrative and technical: the renewal application and work programme require the necessary approvals before a well can proceed.
A large licence refocused on priority targets
PEL 93 covers around 18,500 square kilometres in the Owambo basin, an area that remains little explored. Monitor Exploration operates the licence and holds 55%. The other partners are 88 Energy with 20%, Legend Oil Namibia with 15% and national company NAMCOR with 10%.
The new geophysical interpretation refines understanding of subsurface structures and helps rank prospects. Prospect 9 emerges as the highest-ranked target for future drilling. Geophysics does not directly detect a commercial deposit: it helps model structures and decide where to undertake further work. Only drilling, followed by analysis and testing, can establish whether the targeted formations contain commercially recoverable hydrocarbons.
As part of the requested renewal, the partners have also proposed relinquishing around half the licence area. This reduction would concentrate resources on the thirteen prospects and leads identified as priorities and limit holding costs. It also requires approval from the authorities and partners concerned.
Regional developments strengthen interest without guaranteeing results
Interest in the Owambo basin increased following tests conducted by ReconAfrica in neighbouring licence PEL 73. In July and August 2026, the company announced hydrocarbon flows to surface during tests of two intervals in distinct formations at the Kavango West 1X well. It subsequently said it was preparing an additional horizontal test in the Huttenberg formation.
These reports provide useful regional evidence for evaluating the petroleum system, but concern a different licence and well. They do not demonstrate the presence of hydrocarbons in PEL 93. Reservoirs, source rock maturity, traps and migration conditions can vary between areas. A neighbouring operator’s result can inform hypotheses, but cannot replace checks specific to the block.
For the PEL 93 partnership, the challenge is now to turn interpretation work into an operational programme. It must confirm the renewal, specify the well location, define any additional seismic acquisition needs and establish how drilling will be financed. In May, 88 Energy stated that its 20% interest was fully vested and that it had no remaining funding obligation under the earlier farm-in mechanism. Funding arrangements for any well will therefore have to be organised under future partnership agreements and decisions.
Drilling will provide the next test of the geological case
Operators describe the Owambo basin as a frontier area for petroleum exploration. Its underexplored nature offers discovery potential, but comes with a high degree of uncertainty. Before drilling, interpretation relies on geophysical and geological data and regional analogues. A well would directly test the formations’ nature, porosity, any hydrocarbon saturation and evidence of a petroleum system.
An exploration well’s results extend beyond whether oil or gas is present. Reservoir thickness and quality, pressure, fluid composition and the possibility of a production test help determine subsequent steps. In such a large licence, even a local discovery would require additional work to measure its extent and determine whether it could support commercial development.
For Namibia, the decision could help clarify the geology of an inland basin, while offshore discoveries have already attracted substantial investment into the country. Onshore exploration does not automatically have the same infrastructure or transport conditions, however. Access, water, logistics, environmental protection and community acceptance must be incorporated into any development scenario.
Milestones to monitor before speaking of a discovery
PEL 93 is thus entering a phase in which regulatory and financial decisions will matter as much as data interpretation. Confirmation of renewal, approval of the work programme and selection of a drilling location will be the next concrete indicators. No date for a potential well was announced in the renewal application.
The objective of at least one well opens a new stage for the licence without predetermining its outcome. For investors and energy sector participants, the value of this progress will be measured by the partnership’s ability to fund the programme and test Prospect 9 within a credible timeframe. The next decisive information will specify approvals, the timetable and resources committed in the field.
