Nigeria’s Oil Output Wobbles Despite Rising Rig Activity

 

Nigeria’s increased deployment of oil rigs over the past decade has failed to translate into a corresponding rise in crude oil production, raising fresh concerns about the country’s ability to convert billions of dollars in drilling investments into sustainable output.

Data reviewed by industry analysts show that 2,099 rigs were deployed in Nigeria between 2016 and 2026, representing investments worth billions of dollars. However, crude production has largely stagnated over the same period, with declining output from mature fields and slow development of new wells identified among the major factors. 

Rig count is generally regarded as an important indicator of exploration and production activity because increased drilling should, over time, result in new wells, additional reserves and higher production. Nigeria’s experience, however, suggests that simply increasing drilling activity is not enough to reverse declining production from ageing oil assets. 

The latest figures underline the challenge. Nigeria’s crude oil production declined by four per cent in July 2026 to 1.505 million barrels per day, from 1.565 million barrels per day in June, according to data from the Nigerian Upstream Petroleum Regulatory Commission. Including condensate, total production stood at 1.67 million barrels per day. 

Although the country remained above its OPEC crude-production quota for the third consecutive month, the July decline highlights continuing operational difficulties. The NUPRC attributed a significant part of the reduction to problems affecting production at the Erha and Akpo fields. 

Industry experts told Financial Vanguard that the problem goes beyond the number of rigs operating in the country. Many of Nigeria’s producing fields are mature assets whose output naturally declines with age, requiring substantial investment in new wells, workovers, enhanced recovery and other production-support measures to maintain volumes. 

The situation is particularly significant because oil remains central to Nigeria’s foreign-exchange earnings and government revenue. A sustained inability to translate drilling activity into higher production could therefore limit the economic benefits expected from renewed investment in the petroleum sector.

The development also raises questions about whether Nigeria's ongoing petroleum-sector reforms are yet producing the level of investment and production growth expected by policymakers. Five years after the Petroleum Industry Act was enacted, industry stakeholders are still calling for outstanding implementation gaps to be addressed, warning that regulatory uncertainty could undermine investment and energy security.

Operators, however, have maintained that they remain committed to improving production. Renaissance Africa Energy and Eni, among others, have indicated that efforts are continuing to optimise output and improve the performance of producing assets. 

The figures therefore present a paradox for Africa’s largest oil producer: more drilling activity has not automatically meant more oil. The challenge now is not simply to put more rigs into the field, but to ensure that investment produces commercially viable new wells, offsets declines from mature assets and delivers sustainable production.

For a country seeking to strengthen its revenues, attract fresh petroleum investment and increase its influence within OPEC+, the message is clear: Nigeria may have more drilling activity, but it still needs to turn that activity into barrels.
