Overview
Doba Blend crude oil is produced in Chad and pumped through a 650 mile pipeline across Cameroon to the Kome Kribi 1 Floating Storage Offloading (FSO) facility. The FSO is located 6 miles off the coast of Cameroon. The typical cargo size is 950 thousand barrels; however, alternate cargo sizes can be arranged with advance planning. Production is expected to be 225 mbpd from the second quarter of 2004. Chevron has a 25% interest.
