Seismic ray tracing and wavefront tracking in laterally heterogeneous media
نویسندگان
چکیده
One of the most common and challenging problems in seismology is the prediction of source-receiver paths taken by seismic energy in the presence of lateral variations in wavespeed. The solution to this problem is required in many applications that exploit the high frequency component of seismic records, such as body wave tomography, migration of reflection data and earthquake relocation. The process of tracking the kinematic evolution of seismic energy also brings with it the possibility of computing various other wave-related quantities such as traveltime, amplitude, attenuation, or even the high frequency waveform, which can then be compared to observations.

The fast marching method: an effective tool for tomographic imaging and tracking multiple phases in complex layered media
The accurate prediction of seismic traveltimes is required in many areas of seismology, including the processing of seismic reflection profiles, earthquake location, and seismic tomography at a variety of scales. In this paper, we present two seismic applications of a recently developed grid-based numerical scheme for tracking the evolution of monotonically advancing interfaces, via finite-diff...

Abstract The ray series method may be generalized using a ray centered coordinate system for general 3D-heterogeneous media. This method is useful for Amplitude Versus Offset (AVO) seismic modeling, seismic analysis, interpretational purposes, and comparison with seismic field observations.For each central ray (constant ray parameter), the kinematic (the eikonal) and dynamic ray tracing system ...
متن کاملSeismic velocity estimation and time to depth conversion of time-migrated images
We address the problem of time to depth conversion of time migrated seismic images and show that the Dix velocities estimated from time migration velocities are the true seismic velocities divided by the geometrical spreading of image rays. We pose an inverse problem: to find seismic velocities from Dix velocities and suggest two algorithms for solving this problem. One algorithm is based on th...
متن کاملVelocity Modeling in a Vertical Transversely Isotropic Medium Using Zelt Method
In the present paper, the Zelt algorithm has been extended for ray tracing through an anisotropic model. In anisotropic media, the direction of the propagated energy generally differs from that of the plane-wave propagation. This makes velocity values to be varied in different directions. Therefore, velocity modeling in such media is completely different from that in an isotropic media. The vel...
متن کاملMultiarrival wavefront tracking and its applications
[1] Multivalued traveltimes have traditionally not been used in seismic imaging, with only a handful of notable exceptions in the field of exploration geophysics. For studies at local and regional scales (e.g., local earthquake/teleseismic tomography), the focus has largely been on first arrivals, with numerous rayand grid-based schemes developed for their calculation. However, later arrivals o...
