Few controversies in Nigeria’s oil industry have attracted as much global attention as the long-running dispute over OPL-245, one of the country’s richest deepwater oil blocks.
Estimated to contain about 9 billion barrels of crude oil, the block represents roughly a quarter of Nigeria’s proven reserves. Yet instead of becoming a major source of national revenue, it turned into a symbol of corruption, legal battles, and missed opportunities.
The controversy began in 1998 when the oil block was awarded to Dan Etete, then Nigeria’s Minister of Petroleum Resources, through a company he secretly controlled, Malabu Oil & Gas. Over the next three decades, the block would be revoked, reassigned, sold in a controversial deal to Shell and Eni, and investigated across multiple countries.
Join our WhatsApp ChannelAlthough courts in several jurisdictions eventually cleared many of the accused between 2021 and 2024, the case remains one of the most talked-about corruption scandals in Nigeria’s oil sector. In March 2026, the Nigerian government finally moved toward development by splitting the block into four separate assets.
Here are seven reasons the OPL-245 saga became one of Nigeria’s most notorious corruption cases.
1. One of the Largest Alleged Oil Bribery Deals in History
At the heart of the controversy was a $1.3 billion transaction in 2011 when Shell and Eni acquired the block. Prosecutors alleged that nearly $1.1 billion of the payment was diverted through intermediaries and distributed to politicians and officials.
The scale of the alleged diversion shocked investigators. Reports suggested that hundreds of millions of dollars were converted to cash and distributed through complex financial channels. Allegations even mentioned possible kickbacks to senior political figures, including former president Goodluck Jonathan, though he repeatedly denied any involvement.
2. A Classic Case of Self-Dealing by a Public Official
The scandal began with a striking conflict of interest. In 1998, Petroleum Minister Dan Etete awarded the oil block to Malabu Oil & Gas, a company he secretly owned through proxies.
The deal was made for a $20 million signature bonus, of which only $2 million was reportedly paid at the time. Critics said the arrangement violated Nigeria’s code of conduct rules for public officials and highlighted how powerful individuals could exploit the country’s oil licensing system for personal gain.
3. Allegations of High-Level Political Involvement
Over the years, several senior officials were drawn into investigations connected to the deal. Among them was former Attorney-General Mohammed Bello Adoke, who faced accusations related to legal advice provided during the negotiations.
Former petroleum minister Diezani Alison-Madueke was also mentioned in some investigations. While many of the cases were eventually dismissed or unresolved, the involvement of top government figures deepened public suspicion that political elites had captured control of the country’s oil resources.
4. The Involvement of Major International Oil Companies
Unlike many domestic corruption scandals, OPL-245 drew in some of the world’s biggest energy firms. Investigators accused executives from Shell and Eni of knowingly engaging in negotiations despite concerns about the ownership structure of Malabu and Etete’s previous legal troubles abroad.
The presence of multinational companies turned the dispute into an international story and raised questions about how global energy corporations operate in countries with weak governance systems.
5. A Global Web of Investigations and Court Cases
The dispute triggered investigations and legal proceedings across several countries. Authorities in Italy, the United Kingdom, the Netherlands, the United States, and Nigeria examined various aspects of the deal.
The most prominent case took place in Milan, where executives from Eni and Shell were tried but acquitted in 2021. Appeals were later dropped. Other lawsuits, including Nigeria’s $1.7 billion claim against JPMorgan Chase, were also dismissed. The cross-border legal battles lasted nearly three decades and illustrated the complexity of prosecuting international corruption.
6. Opaque Oil Licensing Practices
The OPL-245 saga exposed deeper structural problems in Nigeria’s oil sector. The block changed hands multiple times—revoked, reassigned, and renegotiated—often without transparent bidding processes.
At one point, the licensing structure significantly reduced Nigeria’s potential share of revenues while allowing international operators to maintain favorable terms. Critics argued that such opaque practices helped create an environment where corruption could thrive.
7. Massive Economic Losses and Development Delays
Despite its huge reserves, OPL-245 remained undeveloped for almost 28 years because of legal disputes and political controversy. Analysts estimate the block could produce 175,000 to 200,000 barrels of oil per day, generating billions of dollars in revenue.
Instead, Nigeria received only about $210 million directly from the deal while potentially losing billions in future income. The delay also meant lost opportunities for economic development and investment in the Niger Delta region.

A Scandal That Still Shapes Nigeria’s Oil Debate
Even though courts cleared most defendants, the OPL-245 dispute left a lasting mark on Nigeria’s oil industry. Investigations by civil society groups such as Global Witness and Human and Environmental Development Agenda helped keep the issue in global headlines and sparked debates about transparency in resource management.
With the Nigerian government’s 2026 decision to split the block into four separate assets, hopes have resurfaced that the long-delayed field may finally be developed. Yet the saga remains a reminder of how governance failures in the oil sector can cost a resource-rich nation billions.
For many observers, the story of OPL-245 is not just about a single oil block—it is about the broader struggle to ensure that Nigeria’s natural resources truly benefit its people.
