The story of NNPC is the story of Nigeria’s oil. You can’t separate them. Before 1977, Nigeria had oil but no single institution to manage it. The government tried different approaches. A national oil company here. A ministry there. Nothing quite worked. Then came 1977. Decree No. 33. The Nigerian National Petroleum Corporation was born. For over four decades, it was the face of Nigerian oil. The good, the bad, and the controversial. Then 2021. The Petroleum Industry Act. The old corporation died. NNPC Limited took its place.

Before NNPC: The Early Years (1956–1977)

The Discovery

Oil was discovered in commercial quantities at Oloibiri in present-day Bayelsa State in 1956. Shell-BP Petroleum Development Company made the find. At that time, Nigeria was still under colonial rule. Independence came in 1960. But oil operations were dominated by international companies. Shell, Mobil, Chevron, Texaco, Agip — they all came. The government was a spectator. It collected taxes and royalties. It issued licenses. But it didn’t participate directly.

Nigerian National Oil Corporation (1971)

That changed in 1971. The government established the Nigerian National Oil Corporation (NNOC). This was the first direct state participation in oil operations. NNOC entered joint ventures with international oil companies. It acquired equity interests in producing fields. It began building local expertise. But NNOC only handled commercial operations. Regulation stayed with the Federal Ministry of Mines and Power. This separation created coordination problems. If you’re trying to understand what NNPC Limited is under the Petroleum Industry Act, the NNOC was its distant ancestor.

The Problem with Separation

Having one body for commercial operations (NNOC) and another for regulation (the Ministry) created friction. Decisions took too long. Responsibilities overlapped. The government realized it needed a single institution. One that could both participate in the industry and oversee it. One with enough power to actually get things done. That realization led to NNPC.

The Birth of NNPC (1977)

Decree No. 33 of 1977

On April 1, 1977, the government issued Decree No. 33. The decree merged NNOC and the petroleum division of the Ministry of Mines and Power into a single entity. The Nigerian National Petroleum Corporation was born. The decree gave NNPC powers to:

• Explore for and produce oil and gas
• Refine crude oil into petroleum products
• Transport and market petroleum products
• Enter into joint venture agreements
• Regulate the industry

For the first time, Nigeria had a unified national oil company.

The Mandate

NNPC was created to manage the government’s interests in the petroleum sector. It was a statutory corporation — a government agency, not a company. Its mandate was broad. It could do almost anything related to oil and gas. And for decades, it did. If you’re curious about the objectives and mandate of NNPC, the original 1977 decree set the template that lasted for 44 years.

The First Decade (1977–1987)

Building Refineries

One of NNPC’s first priorities was refining. Nigeria had one refinery in Port Harcourt (built in 1965). It wasn’t enough. The Warri refinery was completed in 1978. The Kaduna refinery followed in 1980. Together, they gave Nigeria refining capacity of about 270,000 barrels per day. The Port Harcourt complex was expanded with a second refinery in 1989. Total capacity reached 445,000 barrels per day. These refineries were supposed to make Nigeria self-sufficient in petroleum products. That didn’t quite work out. But that’s a story for another day.

Joint Ventures

NNPC inherited NNOC’s joint venture interests. It held equity stakes in concessions operated by Shell, Mobil, Chevron, Agip, and Elf. These joint ventures were the backbone of Nigerian oil production. NNPC typically held 55-60 percent. International partners held the rest. The model worked for decades. But it also created challenges. NNPC often couldn’t pay its share of joint venture costs, leading to cash calls and underinvestment.

The 1988 Restructuring

The government restructured NNPC in 1988. The goal was to improve efficiency and commercial focus. The restructuring created specialized subsidiaries:

• Nigerian Petroleum Development Company (NPDC) — exploration and production
• NNPC Refining — refinery operations
• NNPC Marketing — product sales
• Pipelines and Products Marketing Company (PPMC) — distribution

Each subsidiary was supposed to operate semi-independently. In practice, they remained under strong central control.

The Production Sharing Contract Era (1990s)

Why PSCs?

By the 1990s, Nigeria had explored most of its onshore and shallow water areas. The remaining potential was in deepwater — expensive, risky, technically challenging. The joint venture model required NNPC to pay its share of costs. For deepwater, that was too expensive. The government couldn’t afford it. The solution was Production Sharing Contracts (PSCs). Under PSCs, international oil companies bear the exploration risk. If they find oil, they recover costs from production and share the remaining profit with NNPC.

Major Discoveries

The PSC framework opened deepwater Nigeria. Major discoveries followed:

• Bonga (Shell) — 1996
• Erha (ExxonMobil) — 1999
• Agbami (Chevron) — 1999
• Akpo (Total) — 2000
• Egina (Total) — 2003
• ZabaZaba (ExxonMobil) — 2005

These fields added billions of barrels to Nigeria’s reserves. They also changed NNPC’s role from active operator to concessionaire and profit-taker.

NLNG

The Nigeria LNG project was another major development. NNPC holds 49 percent, with international partners holding the rest. First exports from Bonny Island began in 1999. NLNG commercialized gas that was previously flared. It created a new revenue stream and reduced environmental damage. Today, NLNG is one of Nigeria’s most successful industrial projects. It’s a rare example of something working well.

The Reform Era (2000–2020)

The Petroleum Industry Bill

Efforts to reform NNPC and the broader petroleum sector began in earnest in the early 2000s. The Petroleum Industry Bill (PIB) was introduced in 2007. The PIB proposed sweeping changes:

• Breaking up NNPC into separate entities
• Creating independent regulators
• Introducing new fiscal terms
• Increasing transparency

But the PIB got stuck. For 14 years, it went through multiple versions. Each administration had its own priorities. The National Assembly couldn’t agree. By 2020, the PIB had become a running joke. Everyone agreed reform was needed. No one could agree on what reform looked like.

Transparency Initiatives

Despite the legislative gridlock, NNPC took some steps toward transparency. In 2010, it began publishing monthly financial and operational reports. These reports provided public access to information about production, revenue, and expenditures. In 2015, it published audited financial statements for 2014 — the first time in its history. Previously, NNPC had never made its accounts public. The NNPC financial statements explained show how much was hidden for so long.

The NEITI Connection

The Nigeria Extractive Industries Transparency Initiative (NEITI) played a key role in pushing for transparency. NEITI audits forced NNPC to disclose information it would have preferred to keep private. NEITI reports revealed discrepancies in revenue remittances, questionable expenditures, and underperformance of refineries. Without NEITI, the pressure for reform would have been much weaker.

The Commercialization Announcement (2016)

In 2016, the government announced plans to commercialize NNPC. The goal was to transform it from a government agency into a commercial entity. The announcement was greeted with skepticism. Nigerians had heard reform promises before. But this time was different. The commercialization plan was tied to the pending PIB. The government made clear that the old NNPC would not survive the new law.

The Petroleum Industry Act (2021)

Passage

On August 16, 2021, President Muhammadu Buhari signed the Petroleum Industry Act into law. After 14 years of legislative struggle, the PIB finally became the PIA. The Act fundamentally restructured Nigeria’s petroleum sector. It created new regulatory agencies. It introduced new fiscal terms. And it dissolved the old NNPC.

Section 53

Section 53 of the PIA mandated the incorporation of NNPC Limited. The Minister of Petroleum Resources was required to incorporate the company under the Companies and Allied Matters Act. The old corporation was dead. Long live the company. If you’re trying to understand what NNPC Limited is under the Petroleum Industry Act, Section 53 is where to start.

Incorporation

NNPC Limited was incorporated on September 22, 2021 — just five weeks after the PIA was signed. The Corporate Affairs Commission registered the company with a share capital of ₦200 billion, the highest in Nigeria at the time. The shares were held by the Ministry of Finance Incorporated (MOFI) and the Ministry of Petroleum Incorporated (MOPI), each holding one share on behalf of the federation.

NNPC Limited (2021–Present)

The Transition

The transition from the old NNPC to NNPC Limited wasn’t instantaneous. Assets had to be transferred. Liabilities had to be assumed. Employees had to be moved. Section 54 of the PIA provided for the transfer. The Minister of Petroleum and Minister of Finance were given 18 months to determine exactly what gets transferred. If they didn’t complete the transfer within 18 months, everything was deemed automatically transferred. The law didn’t allow bureaucracy to block the transition.

Early Performance

In 2025, NNPC Limited recorded total revenue of ₦60.5 trillion and profit after tax of ₦3.76 trillion. These numbers would have been unimaginable under the old structure. The company also published audited financial statements, paid taxes, and declared dividends — things the old NNPC never did.

Leadership Changes

In April 2025, President Tinubu dissolved the existing board and appointed new leadership. Bayo Ojulari became Group Chief Executive Officer. Ahmadu Musa Kida became board chairman. If you’re tracking leadership, knowing who is the GCEO of NNPC matters for understanding where the company is headed.

What the History Teaches

Reform Is Possible

The history of NNPC shows that meaningful reform is possible, even when it takes decades. The PIB was introduced in 2007. The PIA was signed in 2021. Fourteen years of struggle, but change eventually came.

Transparency Is Hard-Won

NNPC resisted transparency for most of its history. It took sustained pressure from NEITI, civil society, and international partners to force disclosure. Even now, the battle for transparency continues. But the PIA’s requirements for audited accounts and public disclosure are a major step forward.

The Work Continues

Becoming a company doesn’t automatically make NNPC Limited efficient or profitable. The history of the old NNPC is a cautionary tale about what happens when political considerations override commercial logic. The question now is whether NNPC Limited can overcome that legacy.

The Conclusion

The history of NNPC is the history of Nigeria’s oil industry. From the discovery at Oloibiri in 1956 to the creation of NNOC in 1971 to the birth of NNPC in 1977, the story is one of increasing state control and repeated reform attempts. The Petroleum Industry Act 2021 marked the most fundamental change yet. The old statutory corporation was dissolved. NNPC Limited, a commercial company, took its place. Whether this new entity succeeds where the old one failed depends on consistent implementation, strong governance, and the willingness to put commercial logic ahead of political pressure. The history so far is mixed. The next chapter is still being written.
