Sao Tome and Principe rejected bids for its three offshore oil blocs following its 2026 licensing round, which attracted only Brazil’s Petrobras and Nigeria’s Oranto Petroleum. This decision surprised many, as the Central African island nation had offered unusually generous terms, including up to 85 per cent ownership of the oil blocs.

The government had anticipated that these generous terms would draw numerous competing investors, allowing for better deals and maximised national benefits. However, the submission of bids by only two companies, Petrobras and Oranto, left authorities without sufficient competition to determine the true market value of the assets, leading to the suspension of the process.

Petrobras is Brazil’s state-controlled energy company, boasting assets exceeding 180 billion dollars and significant investments in Brazil’s offshore pre-salt fields and international operations. Oranto Petroleum, founded by Nigerian businessman Arthur Eze, is a privately owned Nigerian oil company that has invested billions of dollars in oil exploration and production across more than 20 African countries.

Shifting Global Oil Investment Landscape

For many observers, Sao Tome’s decision reflects changing realities in the global oil industry rather than a mere failed licensing exercise. Energy experts, speaking to the News Agency of Nigeria (NAN), explained why investors are increasingly shying away from fossil oil.

Wumi Akinola, an Abuja-based petroleum economist, noted that oil companies now invest more cautiously due to rising exploration costs and investor demands for stronger financial returns. Companies increasingly prefer projects with lower risk, stable regulations, established infrastructure, and shorter production timelines.

Frontier exploration, particularly deep offshore drilling, requires billions of dollars before commercial oil production can begin. These massive investments are becoming harder to justify amidst energy transition policies and increasing shareholder pressure for capital discipline.

Kelvin Emmanuel, another expert, added that generous fiscal terms alone no longer attract oil companies. He stated that companies evaluate political stability, contract certainty, operational risks, and expected profitability before committing capital.

Emmanuel highlighted Nigeria’s experience, where an estimated 500–700 oil exploration licences have been awarded, but only about 120–180 advanced into producing assets. He also noted that since 2000, the Ministry of Petroleum Resources and the Nigerian Upstream Petroleum Regulatory Commission issued 47 refinery establishment licences to private investors, with only 31 progressing to construction and six reaching full commercial refining operations.

Wale Ogundipe, Chairman of Global Energy Services, corroborated that the Sao Tome outcome reflects changing investment priorities. Many international oil companies are now focusing on proven reserves rather than expensive frontier exploration, preferring assets that generate faster returns with lower technical and commercial risks.

Nigeria's Imperative for Economic Diversification

Experts emphasised that countries must provide transparent governance, competitive fiscal systems, and predictable regulations to attract long-term investment, as investors compare opportunities across continents. The development in Sao Tome raises deeper economic questions for Nigeria beyond oil licensing.

Despite earning enormous revenues from crude oil exports for more than five decades, Nigeria’s wealth has not produced a diversified economy capable of reducing its dependence on petroleum income. Manufacturing contributes less than expected, agriculture remains underdeveloped, and power shortages continue to hinder industrial growth and increase production costs.

Muda Yusuf, CEO of the Centre for the Promotion of Private Enterprise (CPPE), stressed that diversification is now essential as oil-dependent economies face increasing fiscal pressure amid global energy shifts. He advocated for petroleum revenues to support agriculture, manufacturing, technology, education, and infrastructure to create sustainable jobs and strengthen economic resilience.

The global shift demonstrates that oil reserves alone cannot guarantee investment, with companies increasingly prioritising profitability, certainty, and lower risks. The International Energy Agency projects that while oil demand will persist in the coming years, growth is expected to slow as cleaner energy investments expand globally.
