This report presents a statistical analysis of outcrop-permeability data for quantifying spatial patterns of petrophysical heterogeneity in carbonates that are difficult or impossible to observe in the subsurface.

We examined the relationship between three data types--geologic maps, measurements of pavement deflection under load, and seismic refraction data-- from diverse geologic settings in Texas to determine (1) whether geologic maps and seismic refraction data might be used to interpret deflections and

This report uses the rock fabric method to construct a reservoir model of a Permian Basin Grayburg dolomite reservoir. Rock fabrics are related to porosity, permeability, and capillary pressure and are distributed within a sequence stratigraphic framework.

Because geomorphic features can readily be mapped, our ability to characterize unsaturated flow over large areas would be greatly enhanced if relationships between geomorphic settings and unsaturated flow could be identified.

Six interlocking regional stratigraphic cross sections of Lower Cretaceous strata (middle Albian-lower Cenomanian) of the Edwards and Stockton Plateaus of West Texas illustrate the vertical and lateral extent of lithostratigraphic units and distribution of facies and facies tracts.
