Description
Many multi-disciplinary workflows need to be brought together to build a world-class 3D geological model of the Permian Basin. Advanced techniques such as geomorphology-based modeling (stratalslicing) are critical to properly capturing precise chrono- and lithostratigraphy in 3D seismic surveys. Detailed shelf-to-basin sequence stratigraphic interpretations based on high-resolution well log correlations are critical for guiding the distribution of reservoir parameters. Advanced fault interpretation and automated fault extraction techniques from seismic are essential for building structural frameworks. Following time-depth conversion, facies interpretations obtained from core and seismic attribute analysis are combined with insights into the depositional environments to build an accurate 3D facies architecture. Next, petrophysical results derived from well logs and cores are distributed to obtain 3D facies-conditioned distributions of rock and fluid parameters. Finally, all historical well production and injection data are integrated into the model to enable the testing of a wide range of research hypotheses related to sediment routing, well productivity, enhanced oil recovery, and seismicity analysis. The resulting 3D model integrates the BEG’s understanding of regional geology with detailed reservoir-scale interpretations and are applicable to a wide variety of research areas critical to the decision-making processes of our industry sponsors and the oil & gas industry at large.
