"The US, which had traditionally taken the bulk of Nigeria's crude, has in recent months drastically reduced its demand, which now stands at about 250,000 barrels per day," the Nigerian National Petroleum Corporation (NNPC) said in a statement.
"India, however, now purchases some 30 percent of Nigeria's daily crude production which currently hovers around 2.5 million barrels," it said, quoting senior official Tim Okon.
The state-run NNPC said after India, China and Malaysia were also ahead of the United States, and that Nigeria, which is Africa's largest oil producer, would supply to customers around the world.
Nigeria has been been facing dwindling crude oil sales to the United States as shale oil and gas production there has increased, reducing demand for imports.
