Bonny Light 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.

Bonny Light crude oil is considered to be of the best crude oil in the world because it is easy to refine as a result of the low sulfur content. Due to this factor, BLCO is highly sought after. The Bonny Light is in high demand specifically by American and European refineries. It is therefore a major source of income generation from the oil rich nation.

Bonny Light crude oil is produced in Nigeria from Chevron and Shell concessions. Chevron’s exports are throughput and loaded from the Shell-operated Bonny Terminal, which can accommodate Very Large Crude Carrier (VLCC) loading. The typical cargo size is 950 thousand barrels; however, alternate cargo sizes can be arranged with advance planning. Typically, cargoes are sold with pricing based off Dated Brent quotes. Chevron-operated fields are contributing production of approximately 40 thousand barrels per day. Chevron has a 40% interest in the concession that produces crude oils that are routed to and commingled with Bonny Light crude oil.
