A 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 models of multilayered folded structures so as to generate ray diagrams and synthetic time sections. The purpose of seismic modeling is to provide the seismic interpreter with a tool to aid in the …

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 no width. As such, a ray is a mathematical device rather than a physical entity. In practice, we can produce very narrow beams or pencils (as, for example, a laser beam ...

Ray-Based Seismic Modeling Field managers are required to make costly decisions, relying on data that almost always could be improved. Entire projects are in jeopardy if the wrong questions are asked or answers are not sufficiently sound.
Seismic Ray Tracing

This project involves both Computer Science and Geo Sciences. Seismic Ray Tracing is often used to get information about the Earth's interior. It has its applications in a number of areas in Geosciences including oil exploration and quake fault analysis. An efficient sequential algorithm for ray tracing is being developed by the research group of Dr. Gibson of the Department …

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.

Given a seismic wavefield P(x, z = 0, t) recorded over time t, at the surface z = 0, and along the spatial axis x, seismic migration yields the earth’s reflectivity P(x, z, t = 0) based on a process of wavefield extrapolation in depth z and collecting the image at time t = 0 (migration principles). Conversely, the fundamental ingredient of the modeling process is wavefield …

Ray tracing could even be required for understanding full wavefield modelling results, which makes both modelling approaches highly complementary. Comparison between 1D convolution and 3D convolution as based on the same wavelet and reflectivity grid. 3D convolution takes both illumination and resolution into account.

https://www.crewes.org/Documents/ResearchReports/2000/2000-09.pdf
The seismic modelling capabilities available in the CREWES Matlab toolbox have been substantially upgraded. These capabilities expand an already strong interactive facility to bring a large variety of useful tools to the explorationist or researcher. The v(z) raytracing facility has a fast ray-shooting algorithm that allows an
