Dangote Industries Ltd. aims to run its 650,000-barrel-per-day refinery entirely on Nigerian crude by the end of 2025, a shift that could significantly reduce reliance on imported oil.

According to Bloomberg report, about half of the refinery’s crude supply in June, came from local producers.

As their international obligations expire, these producers are expected to ramp up deliveries to the facility.

“We expect some of the long-term contracts will expire,” vice president at Dangote Industries, Devakumar Edwin said in an interview last week at the sprawling site. “Personally, and as a company, we expect that before the end of the year we can transition 100% to local crude.”

Dangote presented the massive refinery as a way for Nigeria—Africa’s top oil producer—to break free from the costly and corruption-prone cycle of exporting crude to Europe for refining and then importing the finished products.

The refinery’s gradual ramp-up has already made Nigeria a net exporter of petroleum products, even though it has yet to reach full capacity. To bridge supply gaps, the facility has relied heavily on imported crude after local traders failed to deliver enough.

This challenge is compounded by the exit of international oil majors from onshore and shallow water assets, now operated by local companies with fewer resources.

Meanwhile, existing export contracts, crude theft, and frequent pipeline attacks in the Niger Delta continue to limit domestic oil supply.

Since launching operations, the Dangote refinery has purchased crude from Brazil, Angola, Ghana, and Equatorial Guinea, according to Executive Director Devakumar Edwin. He said stronger ties between the refinery, local oil traders, and the government are expected to secure a steady flow of Nigerian crude.

Still, a sharp increase in local supply is needed. In June, domestic producers provided 53% of the refinery’s crude, while 47% came from the United States, according to Bloomberg

The refinery is currently processing 550,000 barrels of crude per day, according to Edwin.

In July, Dangote was allocated five crude cargoes from Nigeria’s state oil company, with the same number scheduled for August, based on cargo allocation data. Each shipment carries nearly one million barrels of crude.
