The Role of Geology in Reservoir Simulation Studies

Abstract: Reservoir simulation models are becoming more and more sophisticated as a result of improved technology and in response to the need to reduce costs and improve hydrocarbon recovery. The improved technology has resulted in part from the development of capabilities for more precise reservoir description, including both the geological and engineering aspects of description. Increased precision in the geological contribution results from (1) improved knowledge of the geologic controls on reservoir rock properties, (2) better methods for synthesizing and quantifying geologic data, and (3) the experience gained from joint engineering-geologic projects.

Constant Pressure Injection Test in a Fractured Reservoir-History Match Using Numerical Simulation and Type Curve Analysis

Abstract: Water was injected at constant pressure into a single well in a fractured reservoir for a period of 32 days followed by a 9 day shut-in period. Intake volumes of the injection well and pressure responses in 19 surrounding wells were recorded during the entire test. Type curves were generated by numerical and semi-analytical techniques to facilitate reservoir characterization from the constant-pressure, declining-rate injection data. A single-phase, three-dimensional, semi-compressible simulator was developed and used to match the field results. The fracture orientation trend of the reservoir was determined, and reservoir permeability and effective fracture length were calculated for the injection well. Type-curves are presented for use in evaluating the constant terminal pressure case for fractured wells.
