São Tomé and Príncipe invites proposals for three offshore oil blocks

São Tomé and Príncipe Opens Three Offshore Blocks for Oil and Gas Exploration

The National Petroleum Agency of São Tomé and Príncipe (ANP‑STP) has issued a call for proposals to explore and develop Blocks 7, 8 and 9 located in the western portion of the country’s exclusive economic zone (EEZ). The announcement, released under Framework Law No. 16/2009 and Regulation ANP‑STP No. 4/2014, invites qualified oil companies to acquire up to an 85 % participating interest in each block.

Geopolitical and Economic Context

São Tomé and Príncipe, a two‑island nation situated in the Gulf of Guinea, possesses an EEZ of approximately 160 000 km². Although the country’s economy relies heavily on agriculture and services, successive governments have identified offshore hydrocarbons as a potential catalyst for diversified growth. Previous licensing rounds in 2015 and 2018 attracted interest from international majors, but no commercial discoveries have been reported to date. The current offering reflects a renewed effort to attract technical partners capable of undertaking deep‑water exploration in a relatively underexplored basin.

Legal Framework Governing the Bid

All submissions must comply with:

• Framework Law on Petroleum Operations – Law No. 16/2009, which establishes the principles for licensing, revenue sharing, and environmental protection.
• Regulation ANP‑STP No. 4/2014, detailing the procedural requirements for bid submission, including the mandatory application fee.

The fee stipulated in the regulation is a non‑refundable USD 25 000 per proposal, payable upon submission of the technical and financial dossier.

Eligibility and Required Documentation

Interested parties—whether single entities or consortia—must provide a comprehensive package that demonstrates both financial capacity and technical expertise. The ANP‑STP specifies the following items:

• Company name, full address, and the designation of a director or responsible person.
• A concise company overview, incorporating audited financial statements for the last three fiscal years and a list of major shareholders.
• An excerpt from the commercial register and the articles of association.
• Where available, a credit rating issued by Standard & Poor’s or Moody’s.
• A balance sheet and profit‑and‑loss statement covering the most recent three financial years.
• A brief narrative of the applicant’s experience in deep‑sea oil and gas exploration, highlighting any relevant projects in similar geological settings.
• For consortium bids, a signed letter of intent from all parties, clearly identifying the intended operator and the share of each participant.

Applicants must indicate the specific block (7, 8 or 9) to which their proposal pertains. Submissions that fail to include any of the above elements may be deemed inadmissible.

Submission Mechanics and Deadline

Proposals may be transmitted either electronically or via postal service. Electronic bids should be sent to info@anp‑stp.st with the subject line formatted as:

“Proposal for Block No. [X] – Announcement No. 01/2026”

Physical submissions must be placed in a sealed envelope bearing the same subject line and delivered to:

The agency stipulates a firm cutoff of 5:00 p.m. (São Tomé and Príncipe time) on 30 June 2026. Any proposal received after this timestamp will not be considered.

Why This Opportunity Matters

For investors, the blocks represent an entry point into a frontier basin with limited prior drilling activity, potentially reducing competition for acreage. The government’s transparent bidding process—anchored in domestically enacted legislation and reinforced by a clear fee structure—aims to mitigate perceived risks associated with operating in a small island state. Moreover, the ANP‑STP’s commitment to publishing all received proposals (subject to confidentiality clauses) enhances accountability and allows stakeholders to assess the level of interest in real time.

From a developmental perspective, successful exploration could generate fiscal revenues, spur local capacity building through joint‑venture training programs, and contribute to the nation’s long‑term energy security. Environmental stewardship remains a prerequisite; applicants are expected to outline mitigation measures aligned with international best practices and the ANP‑STP’s environmental guidelines.

Next Steps for Prospective Bidders

Companies considering participation should:

1. Review Law No. 16/2009 and Regulation ANP‑STP No. 4/2014 in full, available on the ANP‑STP website.
2. Engage local legal counsel to ensure compliance with São Tomé and Príncipe’s corporate and tax regulations.
3. Prepare the required documentation well ahead of the June 30 2026 deadline to accommodate any unforeseen delays in obtaining credit ratings or audited statements.
4. Contact the ANP‑STP directly via the provided email for clarification on procedural points before finalizing the submission.

By adhering to the stipulated guidelines and presenting a robust technical and financial case, interested firms can position themselves to participate in what may become a pivotal chapter in São Tomé and Príncipe’s hydrocarbon narrative.
