3 D seismic image processing for interpretation
Extracting fault, unconformity, and horizon surfaces from a seismic image is useful for interpretation of geologic structures and stratigraphic features. Although interpretation of these surfaces has been automated to some extent by others, significant manual effort is still required for extracting each type of these geologic surfaces. I propose methods to automatically extract all the fault, u...
متن کاملFlexible 3-D seismic survey design
Using all available subsurface information in the design of a 3-D seismic survey, we can better adjust the acquisition effort to the demands of illumination of the target horizon. I present a method that poses the choice of the acquisition parameters as an integer optimization problem. Rays are shot from grid points on the target reflector at uniform opening and azimuth angles and their emergen...
متن کاملPredictive painting of 3-D seismic volumes
Structural information is the most important content of seismic images. I introduce a numerical algorithm for spreading information in 3-D volumes according to the local structure of seismic events. The algorithm consists of two steps. First, local spatially-variable inline and crossline slopes of seismic events are estimated by the plane-wave-destruction method. Next, a seed trace is inserted ...
متن کاملGreens Functions for 3-D Seismic Migration
The space-time Greens functions for 3-D poststack and 3-D prestack migration in a homogeneous medium are derived under the fareld approximation. These Greens functions can be used to practically compute synthetic migrated images. Examples are given for the recording footprint noise associated with a point scatterer and a meandering river channel. The Greens functions also provide fundamental in...
متن کامل3-D Interpretation of Single Line Drawings
The human visual system can interpret two dimensional (2-D) line drawings like the Necker cube as three dimensional (3-D) wire frames. We focus attention on a principle to minimize the entropy of angle distribution between line segments in a 3-D wire frame as a concrete definition of the law of pragnanz in Gestalt Psychology. And we implement the principle with the perceptual preference of plan...
