Oil

Nape urges increased exploration to halt Nigeria reserves decline

The Nigerian Association of Petroleum Explorationists has called for intensified exploration across frontier and mature basins to address depleting oil reserves.

By the CEII Desk, from reporting by Energy Focus Report

Key points

  • Nigeria's oil reserves have declined from approximately 39 billion barrels to 37 billion barrels.
  • NAPE President Cecilia Ajayi advocated for fiscal and regulatory incentives to de-risk frontier exploration.
  • Ajayi suggested adopting a licensing model similar to Ghana's, allowing technical evaluation before signature bonus payments.

What happened

Nigeria must urgently accelerate exploration in both frontier and mature basins to reverse declining hydrocarbon reserves and secure its long-term production future, according to the Nigerian Association of Petroleum Explorationists (NAPE).

Speaking at a strategic panel session during the 2026 NAEC Energy Conference in Lagos, NAPE President Mrs. Cecilia Ajayi stated that the country's oil reserves have dropped from about 39 billion barrels to 37 billion barrels. Energy Focus Report reported that she described sustained exploration as non-competitive without active reserve replacement.

Why it matters

Fuel exports accounted for 85.9 percent of Nigeria's merchandise exports in 2025, according to World Bank figures, underscoring the heavy reliance of the national economy on the petroleum sector. Ajayi warned that without aggressive exploration and the adoption of modern technology to recover bypassed oil in mature fields, the country risks further reserve erosion.

She urged regulators to reform the frontier licensing framework to attract investment. Citing Ghana's model, Ajayi recommended allowing investors to perform limited technical evaluations before committing to full financial obligations, such as signature bonus payments.

Context from CEII

Crude benchmarks move budgets, currencies and inflation in producer and importer countries alike. For economies such as Nigeria, where fuels dominate exports, production and refining decisions move the whole economy.
