Ray tracing seismic
WebThe ray method, also known as the Seismic ray theory ray series method , the asymptotic ray theory (ART) method, or the geometric ray theory (GRT) method, is based on the asymptotic HF solution of the elastodynamic equation for ω → ∞ (where ω is the prevailing circular frequency). Alternatively, the ray series may be also written for ... 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).

WebThe ray vector and the polarization can be obtained from the slowness vector at any given points in the model and the seismic ray path can be traced following the opposite direction of ray vectors. We illustrate the efficiency and accuracy of this new algorithm using 2-D and 3-D numerical examples. WebThe 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 …
WebA ray-tracing modelling of seismic refraction data acquired in the 1960s has been undertaken on two north-south lines - Profile 25 in the western part of the Black Sea and Profile 28/29 crossing ... WebRay tracing has been eminently capable of enhancing the understanding of how seismic waves propagate in anisotropic velocity fields, where physical intuition based on isotropy often fails. The display of raypaths and wavefronts is an educating tool to characterize and describe seismic phenomena including energy focusing and defocusing and the …
WebA new ray-tracing method called linear traveltime interpolation (LTI) is proposed. This method computes traveltimes and raypaths in a 2D velocity structure more rapidly and accurately than other conventional methods. The LTI method is formulated for a 2D cell model, and calculations of traveltimes and raypaths are carried out only on cell … 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 …
