Bonny Light Crude Oil (BLCO) is a high grade of Nigerian crude oil produced in the Niger Delta basin and named after the city of Bonny, Rivers state, Nigeria. The Nigeria National Petroleum Corporation (NNPC) is the principal exporter of for BLCO.BLCO has low sulfur (0.14%-0.16%) content by world standards, so it is in high demand for its low corrosive effects on refinery infrastructure and the low environmental impact of its by-products.
Generally, lighter (high API) crudes are more valuable because they yield more high-value light products when running through a refinery. Light crude oils typically has the 35-45 API range but BLCO has an API of 32.9!
The price of BLCO is based on Brent Crude Oil international “benchmark”.
