More than 12 yr of field development and production at Petrocedeno (formerly Sincrudos de Oriente C.A.) in the Orinoco Heavy Oil belt, Venezuela, have generateda detailed picture of the three-dimensional (3-D) reservoir architecture, static and dynamic properties, and sedimentology of this important deposit. The Petrocedeno project is located along the foreland bulge on the south side of the eastern Venezuelan foredeep basin. Its hydrocarbon is derived mainly from marine source rocks from the early Paleocene to the Miocene; long-distance secondary migration occurred toward the foreland bulge. Traps are stratigraphic in nature, and lateral seal is provided by a combination of biodegraded hydrocarbons and increasingly immobile crude oil. A dense network of wells has enabled the construction of high-resolution static and dynamic models of the fluvial and deltaic reservoir units in the hydrocarbon-bearing lower member of the Oficina Formation.
