Senegal withdraws Nigerian billionaire, Arthur Eze’s oil license
Senegalese authorities have withdrawn offshore oil exploration rights earlier granted to Atlas Oranto Petroleum, a private oil and gas company founded by Nigerian businessman Arthur Eze, as the country tightens control over inactive petroleum licences.
Business Insider reported that the move highlights Senegal’s renewed push to strengthen regulation in its energy sector and fast-track the commercial development of its oil and gas resources.
The government said the licence was cancelled after Atlas Oranto Petroleum failed to fulfil key operational and financial commitments tied to the asset, a requirement authorities insist must be met by all licence holders.
Officials say the decision is part of broader reforms aimed at ensuring that awarded oil blocks are actively developed and contribute meaningfully to national growth, rather than remaining idle for long periods.
The government revoked the Cayar Offshore Shallow exploration license after determining that Atlas Oranto had not provided the required bank guarantees and had carried out only limited exploration work since the block was awarded in 2008, despite several deadline extensions.
The offshore block, which spans about 3,600 square kilometers north of the Dakar peninsula, is regarded as oil-prospective but remains largely underexplored. While seismic surveys identified several potential leads, no exploratory wells were drilled throughout the license period.
Under the oversight of Energy and Petroleum Minister Birame Souleye Diop, the ministry formally terminated the license in September 2025, citing repeated failures by the company to fulfill contractual and financial requirements. Industry sources referenced in early 2026 also confirmed that there was little meaningful seismic or drilling activity on the block.
Senegal has since taken back control of the acreage, describing the move as part of a broader effort by President Bassirou Diomaye Faye’s administration to enforce compliance and apply stricter screening standards to petroleum license holders.
The decision places Senegal among a growing number of African oil-producing countries reassessing legacy exploration contracts signed during earlier licensing rounds. Across the continent, governments are facing increasing pressure to ensure that oil and gas rights result in tangible investment, drilling, and production, rather than being held for speculative purposes.
The revocation has also renewed scrutiny of Atlas Oranto’s wider regional operations. In Liberia, the company secured four offshore production-sharing contracts in September 2025, covering Blocks LB-15, LB-16, LB-22, and LB-24 in the Liberian Basin. Those agreements reportedly included a signature bonus of between $12 million and $15 million, with proposed investments exceeding $200 million per block.
Liberian authorities described the deals as an attempt to revitalize a petroleum sector that has seen minimal activity for more than a decade. However, Atlas Oranto has yet to issue an official response to Senegal’s decision at the time of filing this report.
