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, ...
Chemical remagnetization caused by burial diagenesis: Testing the hypothesis in the Pennsylvanian Belden Formation, Colorado.
(1997)
The TVRM present in Belden carbonates is pervasive whereas the CRM is widespread but site specific, thus providing an opportunity to magnetically characterize the two components. Specimens with the CRM have higher saturation ...
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.
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 ...
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 ...
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 ...
Widespread chemical remagnetization: Orogenic fluids or burial diagenesis of clays?
(1998)
The results of this study indicate that widespread or pervasive chemical remanent magnetizations (CRMs) can form as a consequence of the burial diagenetic conversion of smectite to illite. Paleomagnetic, rock magnetic, and ...
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 ...
Thermal state of the Arkoma Basin and the Anadarko Basin, Oklahoma.
(1999)
Chapter three addresses heat flow and thermal history of the Anadarko Basin and the western Oklahoma Platform. We found no evidence for heat flow to increase significantly from the Anadarko Basin in the south to the Oklahoma ...
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: ...
