Data integration and uncertainty recognition
GCA ensures the integration of geoscience and engineering data to model spatially distributed petroleum reservoir properties as a routine component of reservoir modelling studies and audits. Static geological models integrate in-place volumetric parameter descriptions of reservoirs calibrated to key data. Dynamic simulation models represent geological flow units at an appropriate scale, with dynamic properties calibrated to key flow-test and fluid-sample data. Key uncertainties are explicitly recognized and quantified as part of sensitivity studies. Production forecasts are generated for discrete development project scenarios to provide the basis to test potential economic viability.
