Nigeria origin


Bonny Light oil was found at Oloibiri in the Niger delta region of Nigeria in 1956 for its commercial use.[citation needed] Since then, indigenous people in Nigeria use it as medical treatment, detox, dermal inflammation, digestive disorders, and so on. Due to its features of generating high profit, it is highly demanded by refiners.

Bonny light oil has an API of 32.9, classified as light oil. It is regarded as more valuable than the other oils with lower API as more high-value products are produced in the refinement.

Standard specification of ESPO are API 32.9 and sulfur content 0.14-10.16%.
