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 ...
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 ...
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 ...
The geochemical budget of beryllium in silicic melts and superliquidus, subliquidus, and starting state effects on the kinetics of crystallization in hydrous haplogranite melts.
(2001)
1. An investigation of cordierite-beryl equilibria in hydrous granitic melts using forward- and reversed-direction experiments from 675 to 900° C at 200 MPa (PH2O) has revealed the elucidate limits and mechanisms of ...
Physico-chemical behaviors of shale/fluid/solute interaction in geo-environmental and geo-engineering applications.
(2007)
This dissertation examines the rich and complex physical-mechanical behaviors exhibited by shales when exposed to differing solutions over time, temperature, chemical, and stress conditions. Using several unique experimental ...
Mathematical modeling and ultrasonic measurement of shale anisotropy and a comparison of upscaling methods from sonic to seismic.
(2007)
The theoretical understanding of the effective media modeling is used to model Barnett Shale, which is one of the largest natural gas plays in the World. After the estimation of mineralogical assemblage using FTIR- and XRD ...
Calcite-water reaction rates at reservoir conditions.
(2002)
A numerical model was developed for predicting calcite scale precipitation in near-wellbore regions during water flooding and petroleum recovery operations. Rate equations based on the experimental studies were used to ...
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 ...
