FAULTS AND DISCONTINUITIES ANALYSIS: APPLICATION TO BARNETT SHALE DATA
(2013-05)
Based on the Barnes method of discontinuity filters, I created a new fault-detection attribute and compared it with the constrained least squares spectral analysis (CLSSA) method in Barnett Shale fault detection. The ...
IMAGING CRUSTAL STRUCTURE BENEATH TEXAS FROM RECEIVER FUNCTIONS
(2013-12)
The shallow crust in Texas has been intensively investigated through seismic exploration for hydrocarbon resources. However, the deep crustal structure of Texas is not well understood. This thesis aims to illuminate crustal ...
Multicomponent seismic imaging of sand reservoirs: Middle Magdalena Valley, Colombia.
(2013-05)
Many current resource exploration targets are more difficult to image and assess than in the past; thus, more complete and sophisticated techniques, such as the multicomponent (3C) seismic method, are needed. The scope of ...
Spectral Bandwidth Extension: Invention versus Harmonic Extrapolation
(2014-05)
There are valid and invalid post-processing methods to extend seismic bandwidth for resolution enhancement. Some methods attempt to invent high frequencies without a physical basis, while inversion-based methods extrapolate ...
HISTOGRAM MATCHING SEISMIC WAVELET PHASE ESTIMATION
(2012-05)
The seismic wavelet phase can be estimated by histogram matching between seismic inverted reflectivity and well log reflectivity. Histogram matching is based on the convolutional model and assumes the wavelet is constant. ...
MICROSEISMIC MONITORING: PHYSICAL MODELING AND SOURCE CHARACTERIZATION
(2013-12)
This research investigates some fundamental aspects of microseismic monitoring: location and source mechanism. We developed a ray-tracing and diffraction-stack procedure to determine source locations. The location algorithm ...
RAYLEIGH WAVE TOMOGRAPHY OF TEXAS FROM AMBIENT SEISMIC NOISE
(2013-05)
Texas has been one of the leading states in petroleum production since the discovery of the Spindletop oil field in 1901. Despite its huge economic value of petroleum and numerous geophysical explorations in several oil ...
Fracture Characterization at the Dickman Field, KS: Integrating Well Log and Prestack Seismic Analyses
(2012-08)
Dickman Field, located in Ness County, Kansas, has produced 1.7 million barrels of oil since 1962 and is presently being evaluated by the University of Houston as a potential CO2 sequestration locality. The primary injection ...
ELASTIC, MICROSTRUCTURAL AND GEOCHEMICAL CHARACTERIZATION OF KEROGEN MATURITY FOR SHALES
(2014-05)
This dissertation focuses on how the kerogen content and its maturity affect the seismic properties for organic-rich shale reservoirs. The dissertation links geochemistry, seismic and petrophysics.
The experimental part ...
Investigation of and correction for waveform changes arising from NMO stretch
(2014-05)
NMO-stretch distorts seismic frequency content significantly depending on depths of the target reservoir and offset locations. It causes poor resolution on CMP-stacked sections for image processing, and also creates ...
