MILLIKEN Marathon Oil Company 5555 San Felipe St. Houston TX 77056 Abstract This paper presents an integrated reservoir characterization and simulation study which applies a combination of deterministic and stochastic approaches depending on the amount of data and degree of understanding. The workflow incorporates all available data types like 3D seismic data well logs geologic data core analysis well tests and PVT analysis. Seismic data is first inverted into acoustic impedance which is again inverted into
