88 Energy has pushed ahead with exploration across its sprawling 18,500-square-kilometre PEL 93 acreage in Namibia’s onshore Owambo Basin, with its joint venture (JV) partner now seeking a two-year licence renewal, including plans to prepare for and drill at least one exploration well.
The company holds a fully earned 20 per cent non-operated interest in the Monitor Exploration-operated block. Seismic and technical work in 2024 first mapped what is now the prime target, a large anticline – an upward arch in rock layers capable of trapping oil or gas where suitable reservoir and seal rocks are present – with stacked objectives across three stratigraphic levels.
The principal reservoir objective is the Otavi carbonate sequence, with secondary objectives in the deeper Kombat sandstone. The structure maps with up to 158 square kilometres of closure and 300m of vertical closure, while Monitor believes the block’s central basin position gives its prospects access to an additional source rock.
That foundation has since been strengthened by integrating 203km of modern two-dimensional seismic, almost 6000 line-kilometres of airborne gravity, magnetic and radiometric data and broader geological datasets. 88 Energy says its work has refined Monitor's acreage model and confirmed one particular hotspot, dubbed "Prospect 9", as the highest-ranked drilling opportunity, with the site now classified as drill-ready.
Adding fresh regional sizzle to that case, ReconAfrica’s Kavango West 1X well 100km to the east flowed hydrocarbons from a second interval earlier this month, after initial flows in July. Its Elandshoek Formation produced natural gas to surface on three separate flow tests, while the Huttenberg then flowed hydrocarbons after 75m of interpreted pay was identified.
Both formations sit within the broader Otavi carbonate section, placing the regional flows within the same carbonate package as the joint venture’s principal reservoir objective. For 88 Energy, the results provide another useful piece of the petroleum puzzle, pointing to hydrocarbon generation, migration and, importantly, the ability to flow to surface across the Damara Fold Belt system.
ReconAfrica, meanwhile, is planning to conduct an open-hole horizontal production test targeting up to 1000m of the Huttenberg. While regional rather than direct evidence for its own prospect, 88 Energy believes the results strengthen the hydrocarbon case for its acreage. That improving regional picture now sits alongside its fully earned interest as the project edges closer to the drill bit.
88 Energy managing director Ashley Gilbert said: “With our existing fully earned interest, no remaining farm-in obligation and a pathway to drilling, PEL 93 provides us with a capital-efficient exposure to a potentially significant frontier exploration opportunity that we look forward to advancing alongside our partners”
Subject to Namibian authorities approving the second renewal period from the start of October, 88 Energy and its partners plan to finalise the well location and objectives, complete environmental approvals and baseline studies, progress well design, engineering and costing, evaluate rig and service availability and secure necessary permits before drilling at least one exploration well.
Beyond the prime prospect, several separate structures of comparable scale could also be included in the upcoming work program for further seismic evaluation, allowing the partners to refine and high-grade additional prospects as candidates for multiple shots on goal.
The proposed two-year renewal phase carries a minimum US$10M (A$15.3M) expenditure. Based on its 20 per cent interest and existing pro-rata carry obligations for fellow licence holders NAMCOR, Namibia’s state petroleum company, and Legend Oil Namibia, 88 Energy expects its share to be approximately US$2.67M (A$4.1M).
88 Energy and its partners have also proposed relinquishing 50 per cent of the existing acreage, double the statutory minimum. The company says the move will concentrate exploration on its best ground, retaining all 13 identified prospects and leads while delivering minor cost savings and removing further relinquishment obligations.
Namibia provides the frontier wildcard alongside 88 Energy’s infrastructure-led Alaska North Slope portfolio. While Alaska is built around chasing oil near established fields, roads and pipelines, Namibia is a basin-opening play where regional success could rapidly change perceptions of undrilled ground.
With regional hydrocarbons flowing, a proposed well moving onto the runway and more targets waiting in the wings, 88 Energy has a relatively capital-light seat at what could become a closely watched Namibian exploration show.
