Application of the grid-characteristic method to seismic modeling. Problem statement -- Numerical solution of equations in linear elasticity theory -- Parallel implementation of the numerical method on unstructured grids -- The grid-characteristic method in 3D -- The investigation of seismic responses from multiscale single fractures and fracture systems. Introduction -- General properties of P-wave responses from fractures when specifying boundary conditions on fracture surfaces -- Wave responses from zones of near-vertical aligned mesofractures -- Responses from macrofractures and macrofracture systems : 2D modeling -- Macrofractures in 3D space : the 3D response of a system of near-vertical aligned macrofractures -- Characteristics of seismic responses from megafractures--fracture corridors -- Zones of clusters of random fractures and cavities : analysis of the nature of their response.
Summary:
Using direct seismic responses of fractures and fracture zones to obtain location and characteristic information is a promising direction of investigation. This book addresses properties of fractured media seismic waves by describing, modeling, and analyzing responses from discrete fractured media, and proposes a methodology for direct detection.
