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

Figure 14

Analysis of structural deformation characteristics and fracture facies division in the study area. (a) Structural texture (TMR) inversion attribute, which shows the tectonic deformation characteristics and in situ stress properties of the shale in the study area. (b) Variance attribute, which can be transformed into fracture development intensity. Fracture facies were divided by fracture spreading direction and intensity. In areas where the natural fractures developed, for example, southwest, the average cumulative gas production volume is over , whereas the numerical value is much lower where the fractures are not developed. It is indicated that the proper development of natural fractures has certain positive effects on shale gas development. (c) Fracture facies division based on tectonic stress differences in the study area.
