f Exploring a New Characterization, Modeling and Simulation Workflow for Vietnamese Basement Reservoirs

Hydrocarbon reservoirs offshore Vietnam are unique in that they are produced from structurally elevated igneous rocks that form faulted basement blocks on top of which the Cretaceous to Tertiary siliciclastic sediments were deposited to provide the source rocks of the oil. This paper explores how to construct, parameterize and simulate geologically realistic – albeit heuristic – models of basement and surrounding sediments in Vietnamese basement reservoir to gain answers to the following questions: How can we represent these structurally complex reservoirs in simulation models? Which new approaches can help property modeling? What are the typical drainage areas of wells drilled into basement faults? How much fluid do these produce from within the basement versus the surrounding sediments? How does flow rate affect ultimate recovery?
