Senegalese authorities have revoked the offshore exploration rights held by Atlas Oranto Petroleum, a privately owned upstream oil and gas firm founded by Nigerian energy entrepreneur Arthur Eze.
The decision reflects Senegal’s renewed regulatory stance under President Bassirou Diomaye Faye, aimed at tightening oversight in the energy sector and ensuring that oil and gas licences translate into concrete investment and production.
According to Business Insider Africa, the Senegalese government revoked the Cayar Offshore Shallow exploration licence after determining that Atlas Oranto failed to meet key financial and operational commitments tied to the block.
The licence, awarded in 2008, covers about 3,600 square kilometres north of the Dakar peninsula and is considered oil-prone but underexplored. Despite multiple extensions, the company reportedly carried out only minimal exploration work and failed to provide the required bank guarantees.
Although seismic surveys identified several prospects within the block, no exploration wells were drilled throughout the licence period.
Under the supervision of the Minister of Energy and Petroleum, Birame Souleye Diop, the ministry formally withdrew the licence in September 2025, citing Atlas Oranto’s repeated failure to comply with contractual and financial obligations.
Industry accounts referenced in early 2026 confirmed that the acreage saw little meaningful seismic or drilling activity during the years it was held by the company.
Following the revocation, the Senegalese government reclaimed full control of the block, describing the move as part of a broader strategy to enforce discipline and screen petroleum rights holders more rigorously.
Senegal’s action mirrors a growing trend across Africa, where governments are reassessing long-held oil and gas licences that have failed to deliver investment or production.
With mounting pressure to monetise natural resources, several African producers are moving to reclaim underutilised assets previously awarded during earlier exploration cycles.
Authorities say the objective is to prevent licences from being held purely for speculative purposes and to ensure that petroleum rights result in tangible economic benefits.
The development has renewed attention on Atlas Oranto’s activities across West Africa, where its execution record has drawn scrutiny in multiple jurisdictions.
In Liberia, however, regulators have taken a different approach. In September 2025, the Liberia Petroleum Regulatory Authority signed four production-sharing contracts with Atlas Oranto Petroleum International Ltd covering offshore Blocks LB-15, LB-16, LB-22 and LB-24 in the Liberian Basin.
The agreements reportedly included a signature bonus of between $12m and $15m, alongside proposed investments exceeding $200m per block.
Liberian authorities described the deals as an effort to revive a petroleum sector that has remained largely inactive for more than a decade.
