Shale oil reservoir characterization is conducted in Western Depression of Liaohe Oilfieid of China. The major storage space is fracture which is preferably developed in shale with high content of silica, calcite or dolomite. A workflow of integrating rock physics models, amplitude preserved processing, and pre-stack inversions is developed and implemented which provides elastic parameters such as Young’s modulus, Poisson’s ratio and fracture density and orientation. These parameters are used to characterize brittleness of shale and preferable drilling locations for such kind of reservoir. In order to accurately estimate velocity in shale, a better rock physics model called AS-Xu-White is integrated in the workflow especially for guidance of interpretation, which is modified from Xu-white model. Fluid discrimination in fracture with newly developed anisotropic rock physics model is also employed in this work.
