Bonny light crude oil is a high grade of Nigerian crude oil with
high API gravity (low specific gravity), produced in the Niger
Delta basin and named after the prolific region around the city of
Bonny.
The very low sulfur content of Bonny Light crude makes it a highly
desired grade for its low corrosiveness to refinery infrastructure
and the lower environmental impact of its byproducts in refinery
effluent.
Other grades of Nigerian crude oil are Qua Iboe crude oil, Brass
River crude oil, and Forcados crude oil. The Cabinda crude oil is a
common grade of crude oil produced in Angola. The Bonny Light is in
high demand specifically by American and European refineries. It is
therefore a major source of income for the oil-rich nation.
