Chapter 4: National Oil Companies in West Africa

4.1- Introduction

National Oil Companies (NOCs) play a central role in the management, development and commercialisation of petroleum resources throughout West Africa. In most petroleum-producing countries, NOCs act as representatives of the State in the upstream petroleum sector and serve as important instruments for implementing national energy policies, promoting local participation, developing technical capacity and safeguarding national interests.

Unlike International Oil Companies (IOCs), whose primary objective is to maximise shareholder value, NOCs are generally expected to balance commercial objectives with broader economic, social and strategic national goals. These objectives may include increasing government revenues, developing local expertise, supporting domestic energy security, creating employment opportunities, facilitating technology transfer and promoting industrial development.

The role of NOCs varies considerably across West Africa. Some organisations operate primarily as regulators or State representatives, while others participate directly in exploration, development and production activities as commercial partners alongside international investors. Several NOCs have evolved significantly over time, moving from administrative entities towards commercially focused organisations capable of competing internationally.

As petroleum resources remain among the most valuable assets owned by many West African States, the effectiveness of NOCs can have a significant impact on exploration success, investment attractiveness, production growth and the overall economic benefits generated from petroleum development.

4.2- Historical Development of National Oil Companies

The emergence of National Oil Companies in Africa largely followed the wave of independence movements that occurred during the 1950s, 1960s and 1970s.

Following independence, many governments sought greater control over their natural resources, particularly petroleum resources that had previously been developed primarily by foreign companies. NOCs were established to ensure that governments could participate directly in petroleum operations and secure a larger share of petroleum revenues.

Several factors contributed to the creation of NOCs:

• Resource sovereignty
• Increased government participation
• Revenue generation
• Technology transfer
• Capacity building
• National energy security
• Economic diversification

The creation of the Organization of the Petroleum Exporting Countries (OPEC) and the wave of petroleum nationalisation that occurred during the 1970s further strengthened the role of NOCs globally.

Today, National Oil Companies control the majority of the world’s proven petroleum reserves and account for a significant proportion of global oil and gas production.

4.3- Principal Functions of National Oil Companies

Although responsibilities vary between countries, most West African NOCs perform several common functions.

4.3.1- State Participation in Petroleum Projects

One of the primary functions of NOCs is to represent the State’s commercial interests in petroleum developments.

This may occur through:

• Carried interests
• Participating interests
• Joint venture arrangements
• Production Sharing Contracts
• Direct investment

State participation allows governments to benefit not only from taxes and royalties but also from equity ownership in petroleum projects.

4.3.2- Petroleum Acreage Promotion

Many NOCs assist governments in promoting exploration opportunities to investors.

Activities may include:

• Basin studies
• Seismic acquisition
• Data interpretation
• Licensing round preparation
• Investor presentations
• Virtual data room management

The objective is to improve investor understanding of petroleum potential and increase competition during licensing rounds.

4.3.3- Technical Capacity Development

NOCs frequently act as vehicles for building national technical expertise.

This includes:

• Geoscience training
• Engineering development
• Technology transfer
• Research programmes
• University partnerships
• Professional development

Over time, these initiatives reduce dependence on foreign expertise and strengthen local participation.

4.3.4- Management of Petroleum Data

Many NOCs play an important role in preserving and managing national petroleum data.

This may include:

• Seismic databases
• Well archives
• Core repositories
• Geological libraries
• National data centres

Effective petroleum data management is essential for both resource governance and future investment promotion.

4.3.5- Domestic Energy Security

In several countries, NOCs also support domestic energy objectives through:

• Natural gas development
• Domestic fuel supply
• Refining activities
• Power generation projects
• Strategic fuel reserves

This role is becoming increasingly important as African countries seek to improve access to reliable energy supplies.

4.4- National Oil Companies in Major West African Producing Countries

4.4.1- Nigeria - NNPC Limited

The Nigerian National Petroleum Company (NNPC Limited) is Nigeria’s State-owned energy company and one of the largest National Oil Companies in Africa. Following the enactment of the Petroleum Industry Act (PIA) in 2021, NNPC was transformed from a statutory corporation into a commercially oriented limited liability company.

NNPC participates extensively in upstream petroleum operations through joint ventures, production sharing contracts and direct equity participation. The company is also active in natural gas development, refining, petroleum trading, pipeline infrastructure and energy transition initiatives.

As the largest oil producer in Africa, Nigeria’s petroleum sector remains heavily dependent upon the operational effectiveness and financial performance of NNPC.

4.4.2- Angola - Sonangol

Although Angola is not a member of ECOWAS, Sonangol is included because of Angola’s importance within the African petroleum sector.

Founded in 1976, Sonangol has historically served as both concessionaire and commercial participant in Angola’s petroleum industry. Following sector reforms, licensing responsibilities were transferred to ANPG, allowing Sonangol to focus primarily on commercial operations.

Sonangol remains one of Africa’s most experienced National Oil Companies and has played a significant role in developing Angola’s deepwater petroleum resources.

4.4.3- Ghana - GNPC

The Ghana National Petroleum Corporation (GNPC) was established in 1983 to promote petroleum exploration, manage State participation and develop national expertise within the petroleum sector.

GNPC holds interests in Ghana’s major producing assets, including Jubilee, TEN and Sankofa. The company is widely recognised for its technical capability and active involvement in exploration, development and petroleum policy.

GNPC has become a leading example of a technically competent National Oil Company within Sub-Saharan Africa.

4.4.4- Côte d’Ivoire - PETROCI

PETROCI Holding is the National Oil Company of Côte d’Ivoire and serves as the State’s commercial representative within the petroleum sector.

The company participates in petroleum projects, manages petroleum data, promotes acreage and supports licensing activities. PETROCI has played a central role in recent offshore exploration successes and in maintaining one of the region’s most comprehensive petroleum data repositories.

Recent discoveries have significantly increased PETROCI’s strategic importance within the Ivorian economy.

4.4.5- Senegal - PETROSEN

PETROSEN was established to manage Senegal’s petroleum interests and has become a key participant in the country’s emerging oil and gas industry.

The company holds interests in major developments including Sangomar and Greater Tortue Ahmeyim and plays an important role in local content development, petroleum promotion and gas commercialisation.

As Senegal transitions into a significant hydrocarbon producer, PETROSEN is expected to become one of the most influential NOCs in West Africa.

The Société Mauritanienne des Hydrocarbures et de Patrimoine Minier (SMHPM) represents Mauritania’s interests in petroleum and mining developments.

SMHPM participates in offshore gas developments, licensing activities and resource promotion. The organisation plays a critical role in the development of the Greater Tortue Ahmeyim project and the broader MSGBC Basin.

The future growth of Mauritania’s gas sector will largely depend upon the effectiveness of SMHPM as a commercial partner and State representative.

4.4.7- Benin - Société Nationale des Hydrocarbures du Bénin (SNH-B)

Benin’s National Oil Company is responsible for supporting the development of the country’s petroleum sector and representing State interests in hydrocarbon activities.

Although Benin’s petroleum industry remains relatively small compared with other West African producers, the company plays an important role in promoting investment and supporting exploration initiatives.

Future offshore developments could significantly increase the importance of the organisation.

4.4.8- Niger - SONIDEP

The Société Nigérienne des Produits Pétroliers (SONIDEP) is primarily responsible for petroleum product distribution and energy supply within Niger, while the State also participates in upstream petroleum activities through various government structures.

As production from the Agadem Basin expands and export infrastructure develops, State petroleum institutions are expected to play a growing role in managing hydrocarbon revenues and participation interests.

4.4.9- Guinea-Bissau - Petroguin

Petroguin serves as Guinea-Bissau’s State petroleum entity and supports government participation in petroleum exploration activities.

Although Guinea-Bissau remains a frontier exploration jurisdiction, Petroguin plays an important role in promoting offshore acreage and supporting negotiations with international investors.

The organisation’s future importance will depend on the success of exploration activities within the MSGBC Basin.

4.4.10- The Gambia - GNPC

The Gambia National Petroleum Corporation (GNPC) is responsible for promoting petroleum exploration and representing the State’s interests within the upstream sector.

The corporation supports licensing activities, acreage promotion and petroleum sector development.

As a frontier exploration jurisdiction, the organisation focuses primarily on attracting investment and improving understanding of the country’s offshore petroleum potential.

4.4.11- Guinea - SONAP

The Société Nationale des Pétroles (SONAP) represents Guinea’s interests within the petroleum sector.

Although Guinea has not yet emerged as a significant petroleum producer, SONAP supports petroleum promotion activities, licensing efforts and sector development initiatives.

The organisation’s role may expand if future offshore exploration proves successful.

4.4.12- Sierra Leone - National Petroleum Directorate

Sierra Leone does not currently operate a large commercial National Oil Company comparable to GNPC, PETROCI or PETROSEN. Instead, petroleum sector oversight has traditionally been managed through the Petroleum Directorate and associated government institutions.

Should significant commercial discoveries be developed in the future, Sierra Leone may choose to expand State participation through the creation or strengthening of a dedicated National Oil Company.

4.4.13- Liberia - National Oil Company of Liberia (NOCAL)

The National Oil Company of Liberia (NOCAL) was established to manage Liberia’s petroleum interests and promote exploration activities.

NOCAL has played an important role in licensing activities, petroleum promotion and investor engagement. However, the organisation has faced operational and financial challenges during periods of limited exploration activity.

Future exploration success could revitalise NOCAL’s role within the Liberian petroleum sector.

4.4.14- Togo - Société Togolaise des Hydrocarbures (STH)

The Société Togolaise des Hydrocarbures (STH) represents Togo’s interests in petroleum activities.

Although Togo remains an emerging petroleum jurisdiction, the company supports petroleum promotion, investment attraction and government participation in future developments.

4.4.15- Cabo Verde - ENAPOR and State Energy Institutions

Cabo Verde does not possess a significant upstream petroleum industry and therefore does not maintain a traditional National Oil Company focused on exploration and production.

State energy institutions primarily concentrate on fuel supply, energy security and energy transition initiatives.

Nevertheless, any future offshore exploration activity would likely require the establishment of a dedicated petroleum management structure.

4.4.16- Burkina Faso

Burkina Faso does not currently possess a significant petroleum exploration and production sector. Consequently, no major National Oil Company equivalent to those found in producing countries has been established.

Government institutions focus primarily on downstream petroleum supply and energy security.

4.4.17- Mali

Mali’s petroleum sector remains at an early stage of development, with limited exploration activity and no commercial hydrocarbon production.

Government agencies are responsible for petroleum administration and promotion, while future discoveries could necessitate the creation of a dedicated National Oil Company.

4.5- Common Challenges Facing National Oil Companies

Despite their importance, many NOCs face significant challenges.

4.5.1- Funding Constraints

Many NOCs struggle to finance participation in large petroleum developments.

This may result in:

• Dilution of interests

Key concerns include:

• Political interference
• Procurement practices
• Financial transparency
• Accountability

4.5.3- Technical Capacity

Developing and retaining skilled personnel remains a challenge for many organisations.

Competition from international operators often leads to staff turnover and skills shortages.

4.5.4- Balancing Commercial and Political Objectives

NOCs frequently face competing priorities.

Governments may expect them to:

• Generate profits
• Create employment
• Support domestic fuel supply
• Fund national projects

Balancing these objectives can be difficult.

4.5.5- National Oil Companies and the Energy Transition

The global energy transition is creating both challenges and opportunities for West African NOCs.

Increasingly, NOCs are expanding beyond traditional petroleum activities into:

• Natural gas
• LNG
• Petrochemicals
• Carbon management
