Senegal has revoked offshore exploration rights held by Atlas Oranto Petroleum, the privately owned upstream oil and gas company founded by Nigerian energy entrepreneur Arthur Eze, highlighting a tougher regulatory stance toward long-stalled petroleum licences.
The Senegalese government withdrew the Cayar Offshore Shallow exploration licence after determining that Atlas Oranto had failed to provide the required bank guarantees and carried out only minimal exploration activity since the block was awarded in 2008, despite several extensions.
The licence covers about 3,600 square kilometres north of the Dakar peninsula and is considered oil-prone but remains largely underexplored.
Under the supervision of Birame Souleye Diop, minister of Energy and Petroleum, the ministry formally revoked the licence in September 2025, citing the company’s repeated failure to meet its financial and contractual obligations. Industry sources referenced in early 2026 confirmed that the acreage saw little meaningful seismic acquisition or drilling throughout the licence period, with no wells drilled despite identified leads from earlier surveys.
By reclaiming the block, Senegal has reinforced its intention to enforce compliance and tighten oversight of petroleum rights holders under President Bassirou Diomaye Faye’s administration.
Officials framed the decision as part of a broader policy shift aimed at ensuring that oil and gas licences translate into tangible investment, exploration and production, rather than being held for speculative value.
The move places Senegal among a growing number of African producers reassessing legacy oil and gas contracts signed during earlier exploration cycles.
Across the continent, governments are facing mounting pressure to maximise the economic value of their hydrocarbon resources by holding licence holders to stricter performance and financing standards.
The revocation has also renewed scrutiny of Atlas Oranto’s broader regional footprint, where its execution record has drawn mixed reactions. In Liberia, a contrasting regulatory approach emerged in 2025 when the Liberia Petroleum Regulatory Authority signed four production-sharing contracts with Atlas Oranto Petroleum International Ltd for offshore Blocks LB-15, LB-16, LB-22 and LB-24 in the Liberian Basin.
Those agreements, signed in September, included a reported signature bonus of between $12 million and $15 million and proposed investments exceeding $200 million per block.
Liberian authorities presented the deals as an effort to revive a petroleum sector that has seen limited activity for more than a decade. However, the Liberian contracts quickly attracted criticism from lawmakers and civil society groups.
The Economic Empowerment of Citizens Advocacy Forum called for their suspension, raising concerns over transparency, Atlas Oranto’s financial capacity and potential environmental risks.
Critics also questioned the decision to structure signature bonuses in instalments, arguing that such arrangements weaken enforcement and reduce incentives for early-stage exploration, particularly in high-risk offshore settings.
Senegalese officials said Atlas Oranto’s failure to provide bank guarantees or advance exploration activity over nearly two decades was sufficient grounds for revocation, signalling a governance approach that prioritises delivery and accountability over long-term optionality in the management of petroleum assets.
