Title: FRACTURE AND STRESS CHARACTERIZATION USING LAYER THICKNESS VARIATION
Abstract:
Disclosed herein are embodiments of systems, methods, and computer program products for determining fracture and stress characterization using layer thickness variation over an azimuthally anisotropic medium, which may include one or more of the following functions: acquiring seismic data by recording reflected seismic waves in at least two directions; sorting of the seismic data so that offset is zero at a center and increases radially from a single common-point (CMP) gather for a plurality of data points; generating a multi-dimensional volume by juxtaposing a set of common-offset sections by one of their common-depth point (CDP) and CMP locations; selecting reflectors for each layer in the one of the multi¬ dimensional volume; computing layer parameters including effective anisotropy and interval anisotropy for each layer in the multi-dimensional volume based on a geometry of the reflectors selected for each layer in the multi-dimensional volume; and applying the layer parameters to an earth model.
