Ray tracing seismic
WebApr 26, 2024 · However, the concept of a seismic ray fills an important need. Geometric seismology is not nearly as accurate as geometric optics, but ray theory can be used to solve many important practical geophysical problems. In particular, popular forms of prestack migration are based on tracing the raypaths of the primary reflections. WebA system for measuring a property of fluid in an earth formation includes a downhole tool disposed in a borehole and configured to be movable within the borehole and a nuclear magnetic resonance (NMR) measurement device including a transmitter configured to emit at least two pulse trains of magnetic energy into the earth formation and a detector …

WebSeismic 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 Geology and Geophysics at Texas A&M University. WebJul 1, 1993 · Dynamic ray tracing (DRT) is important in evaluating high-frequency seismic wave fields in complicated structures. Two formulations of the DRT equations for inhomogeneous anisotropic media are presented. One of them is represented by the classical DRT system, suggested by Cerveny 15 years ago. Both systems are specified in …
WebRay tracing is used to test the feasibility of time-lapse effects as well as resolution limitations for a thin sand reservoir. ... Time-lapse 4D seismic is a powerful tool for reservoir investigation that may be utilized to monitor reservoirs where changes in the zone of interest are measurable using surface reflection methods. WebWe present an accurate 3D ray-tracing algorithm based on a modified (more flexible and economical) shortest-path method (SPM). Unlike the regular SPM in the 3D case, which uses only primary nodes at the corners of each cell and whose accuracy depends on actual cell size, the new method can work with much larger cell sizes by introducing secondary …

WebDescription. RayTracing objects are propagation models that compute propagation paths using 3-D environment geometry [1] [2]. Represent a ray tracing model by using a RayTracing object. This ray tracing model: Is reasonable from 100 MHz to 100 GHz. Computes multiple propagation paths. Other propagation models compute only single propagation paths.
WebAbstract. Two methods for tracing seismic rays between 2 given end points through three dimensional, continuously varying velocity structures are available. This paper describes and compares them for problems of practical interest and for analytical ray paths through an idealized velocity structure.
