Petroleum Directorate of Sierra Leone

What Petroleum Directorate of Sierra Leone does

The Petroleum Directorate of Sierra Leone (PDSL) is the sole governmental regulatory and administrative authority for Sierra Leone's petroleum sector, established in 2003 and positioned directly under the Office of the President. PDSL's mandate, anchored in the Petroleum (Exploration & Production) Act, 2011, covers the monitoring and regulation of all upstream and midstream oil and gas activities for the State, including the negotiation and award of petroleum licenses, reconnaissance permits, and exploration agreements. The organization is staffed by 11–50 personnel across technical, finance, legal, geology, geophysics, ICT, procurement, and compliance functions and is headquartered at 20 Mandalay Street, Kingtom, Freetown.

PDSL's technical core is a national petroleum data infrastructure rather than a software product: a digital well database assembled with TGS and PVE Consulting, 4,610 km of 2D seismic, 3,369 sq.km of 3D seismic, 6,745 airborne magnetics data points, and shipborne grav-mag surveys across Sierra Leone's offshore basin. Access to this aggregated dataset is commercialized via data rooms operated in Freetown, London, and Houston. The commercial offering to international and independent oil and gas companies spans the Fifth Offshore Licensing Round (56 blocks), direct-negotiation license awards, and reconnaissance permit agreements, supported by a formal licensing framework, prequalification guidelines, and bid evaluation scorecards.

The Directorate generates income primarily through application and licensing fees, reconnaissance permit fees, data licensing charges, and contingent future production royalties. The State is establishing its first national oil company with a mandatory 10% carried interest, and offshore drilling is scheduled to resume in 2026 after a near-decade pause, following recent major engagements with Eni S.p.A. (2025 Reconnaissance Permit Agreement on five blocks), F.A Oil Limited (2023 license award on six blocks), and earlier reconnaissance deals with Wildcat Petroleum and Innoson Oil and Gas. PDSL does not offer AI-enabled products, software platforms, or developer APIs.

Direct peers

• PETROSEN (Société des Pétroles du Sénégal): Senegalese national oil company with an exploration mandate in the same MSGBC basin directly north of Sierra Leone. Highly comparable as a West African NOC pursuing frontier deepwater exploration.
• Société Mauritanienne des Hydrocarbures et de Patrimoine Minier (SMHPM): Mauritania's state hydrocarbon authority governing upstream licensing in the same MSGBC basin where recent major discoveries (e.g., Tortue/Ahmeyim) have occurred, with directly comparable regulatory scope to PDSL.
• Ghana National Petroleum Corporation (GNPC): Ghana's national petroleum entity with upstream exploration, licensing and regulatory coordination roles in West Africa, directly comparable to PDSL's mandate in Sierra Leone.
• Société Nationale des Pétroles du Congo (SNPC): Republic of Congo's national petroleum company with upstream operations and state participation, directly comparable as a sub-Saharan African NOC with licensing and royalty management duties.
• ANPG - Agência Nacional de Petróleo, Gás e Biocombustíveis (Angola): Angola's national petroleum regulator responsible for managing upstream licensing rounds, technical data, and exploration promotion. Functionally identical to PDSL's mandate and the closest analogous African peer.
• NAMCOR (National Petroleum Corporation of Namibia): Namibia's national petroleum company with a frontier exploration mandate in the Orange Basin, analogous to PDSL's frontier basin role in Sierra Leone.

Others

• Viridien (formerly CGG): Geoscience firm offering seismic data acquisition and reservoir characterization services that interface with African regulators and operators. Included as OTHERS given its parallel role as a multi-client data ecosystem participant.
• PGS (Petroleum Geo-Services): Norwegian multi-client geoscience data provider operating alongside national petroleum authorities in Africa. Included as OTHERS because PDSL's data-room operations are analogous to PGS's multi-client seismic library model.
• TGS: Multi-client geoscience data company that is already an existing technology partner of PDSL (joint development of the digital well database), directly comparable to PDSL's data-management offering.

Broad incumbents

• NNPC Limited (Nigerian National Petroleum Company): Nigeria's much larger national oil company with a broader portfolio spanning upstream, refining and distribution. Included as a BROAD_INCUMBENT regional benchmark for state-led oil and gas activity in West Africa.
