Comprehensive Prediction for Fractured Carbonate Reservoir in the Tarim Basin

Although increasingly employed for estimating both fracture density and orientation by the industry, the P-wave pre-stack anisotropic inversion using pre-stack azimuthal data is only effective for predicting fractures with a similar orientation, but essentially incapable of predicting multiple sets of fractures with different directions. In comparison, numerical simulation of tectonic stress field is proven to be a feasible way in overcoming this shortcoming. In this paper, these two methods are integrated to comprehensively characterize the complex fractured carbonate reservoirs in the Tarim Basin. As a result, both the single set of fractures and multiple sets of fractures are reasonably characterized, suggested by the good agreements with FMI information and geologic settings. This research could find its value in complex fracture reservoir prediction.
