Numerical Solution of Two Seismic Problems with Grid-Characteristic Method in a Full Three-Dimensional Setting
Abstract
Seismic prospecting is the routine method of locating oil and gas fields. In view of the discovery of non-traditional reservoirs, an important task is the development of new procedures for processing field data. The development of high-performance computing systems allows simulating seismic wave propagation processes in heterogeneous geological environments to prepare synthetic- seismograms with high precision. The article presents the use of the grid-characteristic method on hexahedral grids, which describes correctly the curved boundaries between geological layers and explicitly identifies fractured inclusions. The problem of waves’ propagation from an earthquake source occurring in the shelf area is solved; a complete three-dimensional picture of the process is obtained. A study of the passage of seismic waves through a fractured medium with a variation in the fracture parameters is undertaken. The kinematic and dynamic anisotropy of the signal recorded on the day surface is estimated.
