Ray tracing seismic
WebDesigned and implemented 3D visualisation and interaction components for interactive seismic ray tracing. This prototype integrated off-the-shelf software with proprietary algorithms and could therefore be implemented in under four months by a small team. Weniger anzeigen 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.

WebThe ray series method is used to study propagation of seismic waves in the three-dimensional media consisting of generally inhomogeneous layers separated by curved interfaces. The investigation is carried out with the help of the so-called ray centered corrdinate system which was proposed by Popov and Pšenčík (1978a). WebLet's look at some examples of multiple reflection events in seismic data. We review what the multiple is and show some examples of waterbottom and interbed ...
WebFundamentals of Ray Tracing Rick Aster March 28, 2011 A key observation that we can make about a seismic signal is its arrival time. From systematic observations of arrival times, we can deduce useful properties (e.g., velocity or attenuation) in the Earth. Indeed, much of the early history of 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 …
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.
