Top 10 most influential oil companies in Africa in 2025

While Africa continues to play a key role in the global oil industry, several companies are emerging as major players in 2025. Between strategic expansions, technological innovations and environmental challenges, here is the ranking of the 10 most influential oil companies on the continent this year.

1. Sonatrach (Algeria)

The undisputed leader in Africa, Sonatrach is strengthening its position through massive investment in fossil fuels and renewable energies. The Algerian company dominates the natural gas market and is extending its influence in Europe and sub-Saharan Africa.

2. NNPC (Nigeria)

The Nigerian National Petroleum Corporation (NNPC) remains a giant, despite security and regulatory challenges. Its transition to a commercial company and its partnerships with majors such as Shell and TotalEnergies are consolidating its economic weight.

3. TotalEnergies (France, pan-African operations)

France's TotalEnergies maintains a strong presence in Africa, particularly in Mozambique, Angola and Uganda. Its investments in oil and gas, coupled with solar projects, make it an influential hybrid player.

4. Sonangol (Angola)

Despite some difficult years, Sonangol is repositioning itself thanks to reforms and the exploitation of deepwater oil fields. Angola remains a key supplier to Asia, reinforcing the importance of its national company.

5. ENI (Italy, extensive operations in Africa)

Italy's ENI is stepping up its projects offshore Côte d'Ivoire, Egypt and Libya. Its gas strategy and initiatives to reduce carbon emissions are winning over investors.

6. Aramco (Saudi Arabia, African expansion)

Saudi Arabia's Aramco is expanding its footprint in Africa through acquisitions and joint ventures, notably in Egypt and South Africa. Its financial strength is enabling it to rival the incumbent players.

7. Tullow Oil (United Kingdom, focus on West Africa)

Specialising in exploration, Tullow Oil is counting on Ghana and Kenya to boost its production. Despite past difficulties, it remains a key player in African oil.

8. Kosmos Energy (USA, active in Senegal and Mauritania)

Kosmos Energy is playing a central role in the development of the Greater Tortue Ahmeyim gas field. Its discoveries make it a strategic partner for Europe in its quest for natural gas.

9. Sahara Energy (Nigeria)

This privately-owned Nigerian group stands out for its downstream operations and distribution network across Africa. Sahara Energy is strengthening its positions in refining and oil trading.

10. Libyan National Oil Corporation (Libya)

Despite political instability, Libya's NOC is maintaining significant production. The resumption of exports and new contracts with the Europeans have put it in the top 10.

In 2025, these companies will have to reconcile profitability with the energy transition. Investments in natural gas (which pollutes less than oil) and green energies are on the increase, while climate pressures are pushing for more responsible operations.

Africa, with its immense reserves and growing local demand, remains a fiercely competitive arena where the historic giants rub shoulders with new Asian and Middle Eastern entrants.
