A Workflow for Integrated Geological Modeling for Shale Gas Reservoirs: A Case Study of the Fuling Shale Gas Reservoir in the Sichuan Basin, China

Shale gas reservoir evaluation and production optimization both require geological models. However, currently, shale modeling remains relatively conventional does not reflect the unique characteristics of reservoirs. Based on a case study Fuling in China, an integrated workflow for reservoirs is proposed to facilitate its popularization application well improved quality comparability. This involves four types models: structure-stratigraphic model, (matrix) parameter natural fracture (NF) hydraulic (HF) model. The strategies used models vary due uniqueness A horizontal-well lithofacies sublayer calibration-based method employed build key building model lies joint characterization “sweet spots.” NF are built at various scales using methods. models, HF by extended simulation microseismic inversion. In entire workflow, certain sequence mutually constrain one another. addition, contains effectively integrates multisource data. Moreover, multiple integration processes, which quality. selection methods, innovation development algorithms, techniques uncertainty areas where breakthroughs may be possible allows complex process more systematic. It great significance dynamic analysis development, from individual wells field, optimizing schemes systems.
