Resource characterization and residuals remediation: Task 1.0. Semi-annual report, March 1--June 30, 1993

Description: The resource characterization and residuals remediation task embraces the beginning and the end of the energy use cycle. It provides fundamental characterization of fuel and associated resources so these can be used most effectively. Once resources have been used, any residues produced must be used and or disposed of in an environmentally compatible manner. Sulfur, for example, is widespread throughout the environment in many forms. Understanding the occurrence, transport, and fate of sulfur as… more

Predicting the Transport Properties of Sedimentary Rocks From Microgeometry

Description: The author investigates through analysis and experiment how pore geometry, topology, and the physics and chemistry of mineral-fluid and fluid-fluid interactions affect the flow of fluids through consolidated/partially consolidated porous media. The approach is to measure fluid permeability and electrical conductivity of rock samples using single and multiple fluid phases that can be frozen in place (wetting and nonwetting) over a range of pore pressures. These experiments are analyzed in terms … more

Dip-moveout processing by Fourier transform in anisotropic media

Description: Conventional dip-moveout (DMO) processing is designed for isotropic media and cannot handle angle-dependent velocity. The authors show that Hale`s isotropic DMO algorithm remains valid for elliptical anisotropy but may lead to serious errors for non-elliptical transversely isotropic models, even if velocity anisotropy is moderate. Here, they present an extension of Hale`s constant-velocity DMO method to anisotropic media. The DMO operator, to be applied to normal-moveout (NMO) corrected data, i… more
