Seismic ray tracing
WebAbstract. The concept of a ray is very useful. It is a line drawn in space that corresponds to the direction of the flow of radiant energy. Rays are a geometric idealization; they have … WebRay tracing has traditionally been the method of choice in many seismic applications due to its high accuracy and potential for computational efficiency. Common ray tracing schemes include shooting, bending and pseudo bending.

WebFeb 3, 2010 · Summary. Dynamic ray tracing is a powerful procedure that has recently found broad applications in the evaluation of high-frequency seismic wavefields in laterally … WebA new approximate algorithm for two-point ray tracing is proposed and tested in a variety of laterally heterogeneous velocity models. An initial path estimate is perturbed using a geometric interpretation of the ray equations, and the travel time along the path is minimized in a piecewise fashion.
WebA seismic model accepts a description of the subsurface of the earth as input and produces a synthetic seismic record as output. In raypath modeling, ray tracing is carried out for … WebThe core products are seismic modeling packages. These include 2D and 3D seismic ray modeling (Open Ray Model), seismic acquisition and processing optimization, PSDM simulation (SimPLI approach), reservoir analysis and time-to-depth conversion based on ray tracing technology.
WebThis algorithm is suitable for computer applications. In this study, for single-layer case, an iterative inversion technique has been applied to reversed shooting seismic refraction data collected by in-line profiling. The iterative inversion technique used in the present study is based on ray tracing in homogeneous and isotropic media. WebMar 1, 2013 · Seismic ray tracing is one of the most important tools in seismology which is required in many applications such as body wave tomography and exploration seismology. Due to the large amount of data introduced in global tomography, most studies are still using one-dimensional (1D) ray tracing methods. Furthermore, since three-dimensional …
WebJan 19, 2024 · There are two classes of seismic modeling: ray tracing and wave equation methods. Implementation of both classes exists for one, two, and three dimensions; shot gather; common midpoint (CMP) gather; and stacked data simulation. Ray theory uses the fact that energy in the form of rays travels along minimum time paths in the model.
