Overview
N'Kossa crude oil is produced in the Republic of the Congo. It is lifted as N'Kossa Blend which is a blend of N'Kossa and Kitina crude oils. N'Kossa Blend is loaded from the Total-operated Djeno Terminal, which can accommodate Very Large Crude Carrier (VLCC) loading. The typical cargo size is one million barrels. Typically, the cargoes are sold with pricing based off Brent (Dated) quotes. The production rate of the contributing fields is approximately 32 thousand barrels per day. Chevron has a 30% interest in the concession.
(A new assay of N'Kossa Blend is in progress. The following estimated data appears representative of recent cargoes and can be used until the new assessment becomes available.)
