OPEC+ decided in April to return 2.1 million barrels per day (bpd) of supply to the market from May to July, anticipating rising global demand despite the high number of coronavirus cases in India, the world's third-largest oil consumer.
The list includes major Swiss trading firms Trafigura, Vitol and Mercuria, oil major Total as well as large Nigerian traders Sahara Energy, Oando and MRS Oil.
The contracts, known as direct sale, direct purchase (DSDP) are coveted since they are used to supply nearly all of Nigeria's gasoline needs as well as cover some of its diesel and jet fuel consumption.
