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 ... -
Heat flow in Oklahoma.
(1997)Twenty-seven new heat-generation estimates, along with 22 previously published data, are used to create a heat generation map of Oklahoma. The range of heat production estimates is 1.1-3.5 $\mu$W/m$\sp3, $ with an average ... -
A hierarchical, multiscale texture segmentation algorithm for real-world scenes.
(2001)We also develop a way of objectively evaluating texture segmentation algorithms on natural and synthetic texture patches. Finally, our multiscale segmentation approach is demonstrated on several families of real-world ... -
HIGH RESOLUTION SEQUENCE STRATIGRAPHY AND SEISMIC STRATIGRAPHY OF THE LEONARDIAN BONE SPRING FORMATION DELAWARE BASIN, SOUTHEAST NEW MEXICO
(2019-08-01)A high-resolution sequence stratigraphic investigation integrating 3D seismic with petrophysics of the Leonardian Bone Spring Formation, Northern Delaware Basin, New Mexico reveals the sedimentologic process-response ... -
High Resolution Sequence Stratigraphy of the Leonardian Bone Spring Formation Outcrop of Bone Canyon, Guadalupe Mountains, West Texas and its Correlation to the Subsurface
(2020-05)The purpose of this Thesis is to analyze the Upper Leonardian Bone Spring Formation, Cutoff Formation, and Early Guadalupian Brushy Canyon Formation in the outcrop of Bone Canyon located along the Western Escarpment of the ... -
The impact of Oklahoma's winter wheat belt on the mesoscale environment.
(2003)The research documented in this manuscript demonstrates that Oklahoma's winter wheat belt has a significant impact on the near-surface, mesoscale environment during growth and after harvest. Differences in near-surface ... -
The impact of radar data assimilation on the Chorwon-Yonchon 1996 heavy rainfall event.
(2003)One of the most effective tools for observing the atmosphere at fine scales is the Doppler radar. In recent years, considerable research has been directed toward using radar data as a component of numerical prediction model ... -
Integrated Geophysical Studies of The Northeastern Caribbean Plate, Eastern Tibetan Plateau in China and Panhandle Field (Texas)
(2014-06)There are three different areas and research projects that are the targets of this proposed dissertation. These projects have the common theme of integration of a variety of data but are at different scales. The first one ... -
INTEGRATED INTERPRETATION OF BOREHOLE MICROSEISMIC DATA FROM HYDRAULIC FRACTURING STIMULATION TREATMENTS
(2014-05)Sequence stratigraphic principles provide means to interpret the geological framework and likelihood of finding hydrocarbon–bearing rocks. In this work, I show that they can also be used to predict and better interpret the ... -
Interpretational variations of seismic attribute analysis as compared within the time and depth domains
(2022)Migration is one of the crucial data processing steps re-locating the recorded seismic events to their true locations, suppressing the diffractions and thus, providing more accurate imaging of the subsurface. It can be ... -
Iterative model-guided post stack seismic imaging and interpretation of halokinetic structures: Ras Banas area, offshore northern Red Sea.
(1998)Offshore northern Red Sea salt basins are dominated by complex halokinetic features and variable seafloor topography. The resulting severe imaging distortions observed on seismic profiles from these basins mask the salt ... -
Kinematic, dynamic, and thermodynamic impacts of hook-echo hydrometeors, including explorations into the utilization of polarimetric radar data.
(2002)The role hook-echo hydrometeors play in driving RFDs is investigated by estimating hook-echo hydrometeor types and amounts from polarimetric radar data and by using that information to drive a relatively simple downdraft ... -
Laboratory imaging of hydraulic fractures using microseismicity.
(2002)Developing robust algorithms and software for locating the coordinates of hydraulic fracturing-induced microseismic events, and for simulating the first motion of the induced waveforms were central tasks for this research. ... -
Linking image processing and numerical modeling to identify potential geohazards
(2017-08)Faults, along with natural fractures, may enhance production when confined within the reservoir. However, if the fault is connected to an aquifer, it may cause early water breakthrough in the reservoir. Even if they are ... -
Long offset seismic data analysis for resources plays
(2014-07-31)Wide-azimuth, long-offset seismic surveys are becoming increasingly common in unconventional exploration plays, where three the key objectives are to estimate the direction of maximum horizontal stress, to predict the ... -
Machine assisted quantitative seismic interpretation
(2017-05)During the past decades, the size of 3D seismic data volumes and the number of seismic attributes have increased to the extent that it is difficult, if not impossible, for interpreters to examine every seismic line and ... -
Magnetic minerals: Understanding the processes of formation in soils and clays and identifying their presence in the rock record.
(2001)This work presents results of biological formation of magnetite under a variety of laboratory conditions in a hydrocarbon-contaminated soil profile. Magnetite was formed only in biological samples but not in the abiotic: ... -
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 ... -
Measurements and modeling of the Great Plains low-level jet.
(2003)This dissertation describes a project to elucidate the turbulent and momentum structure of the Great Plains Low-Level Jet (LLJ), primarily by the use of Doppler radar. Simple theoretical and numerical models of the LLJ are ... -
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 ...
