Dynamic warping of seismic images
TL;DR: In this paper, a nonlinear accumulation of alignment errors is used to estimate relative time (or depth) shifts between two seismic images, where shifts are large and vary rapidly with time and space, and where images are contaminated with noise or for other reasons are not shifted versions of one another.
Journal ArticleDOI
Wave-equation reflection traveltime inversion with dynamic warping and full-waveform inversion
TL;DR: In this article, a wave-equation reflection traveltime inversion (WERTI) was proposed to estimate the time shifts between recorded data and synthetic data in reflection seismology.
Journal ArticleDOI
Methods to compute fault images, extract fault surfaces, and estimate fault throws from 3D seismic images
TL;DR: This work used an efficient algorithm to compute images of fault likelihoods, strikes, and dips from a 3D seismic image, and automatically extracted fault surfaces as meshes of quadrilaterals that coincide with ridges of Fault likelihood.
Journal ArticleDOI
Stable explicit depth extrapolation of seismic wavefields
TL;DR: In this paper, a modified Taylor series method was proposed to derive stable explicit filters for depth extrapolation of seismic wavefields through a modification of the conventional Taylor-series method, which yields extrapolators with maximally flat amplitude spectra in their passband, while ensuring that no spectral components in the wavefield are amplified by any factor greater than one.
Journal ArticleDOI
3D seismic image processing for faults
Xinming Wu,Dave Hale +1 more
TL;DR: This work has represented a fault surface using a simpler linked data structure, in which each sample of a fault corresponded to exactly one seismic image sample, and the fault samples were linked above and below in the fault dip directions, and left and right in the Fault strike directions.
