Anisotropic effects upon amplitude-vs-offset response in realistic earth models.
(2000)
The derivation and computation of the reflection coefficient for general anisotropic media is described along with software written to implement the computation. This program is then used to compare the reflection response ...
Seismic inversion by artificial neural networks.
(2001)
The first application is seismic inversion. Artificial neural networks were used to invert post-stack seismic data into the petrophysical attributes. This application involves two steps. In the first step, the seismic data, ...
Quantitative analysis of material contrasts and wave propagation in periodic layered media.
(2006)
Dispersive behavior is studied in detail. It is shown that there are critical contrasts at which different stop-bands disappear, as well as a critical angle at which all stop-bands disappear. This characterization of the ...
Methods of velocity determination and noise reduction in the processing of near-surface seismic reflection data.
(2000)
At the Gypsy Outcrop Site, OK, the depth of interest is less than 100 ft. 2-D seismic surveys used a shotgun as source. The signal/noise ratio is very poor. CMP stacking fails to produce interpretable reflections. Because ...
AVO polarization attributes and hodograms.
(2001)
A case study using seismic data from the Gorgon field of the NW Shelf of Australia is done to validate the methodology. Application of this new scheme can help one recognize AVO anomalies and enhances AVO interpretation.
Seismic detection of fault zone hydrocarbon conduit-seal potential using velocity, frequency, and Q analysis: La Concepcion Field, Lake Maracaibo Venezuela example.
(2006)
The 3-D Post-Stack Time Migrated Seismic Data of La Concepcion Field, Maracaibo Basin, Venezuela cover an existing field with known oil and gas pay zones. The thesis problem is how to use this seismic data in an interpretation ...
Seismic wave characteristics in anisotropic attenuating media .
(2006)
Seismic anisotropy in shales is a complex phenomenon. A number of theoretical shale models are investigated to study the effects of clay orientation, aspect ratio of cracks, porosity and fluid types on the synthetic seismograms.
Geologically and well-log constrained quality factor (Q) analysis for seismic reservoir characterization.
(2005)
Measurements of P- and S-wave velocities are conducted on alternating layers of acrylic and aluminum. In this experiment, both thickness of the layers, and frequency of the propagating wave are varied. Based on these ...
Pseudo-inverse imaging for ground penetrating radar data.
(2001)
Ground Penetrating Radar (GPR) is a proven method of characterizing the shallow subsurface. Most interpretations using GPR have relied upon raw data records or records that have been processed with seismic data processing ...
Mechanisms and rates of strength recovery in laboratory fault zones.
(2001)
The results of this investigation may be applied to explain observations of rapid strengthening along large, active crustal fault zones such as parts of the San Andreas Fault system in California and the Nojima fault in ...
