An outcrop study of the Shannon sandstone, conducted in October 1985, resulted in recovering 427 1-inch diameter core plugs, which were documented by geologic description and photographs. Permeability and porosity measurements of the samples will allow studies of: (1) lateral variability of these parameters on several scales; (2) effect of geologic factors on the spatial distribution of k and phi; (3) applicability of outcrop data to subsurface reservoirs; and (4) generic techniques for describing and integrating spatial variability in reservoir and outcrop data. Petrographic and SEM analysis of the samples will supplement K and phi data by indicating lateral distributions of clay content, mineralogy, and pore-filling cement types. Preliminary analysis and comparison of 142 permeability measurements from the Shannon sandstone in the reservoir to 204 measurements from an equivalent 1-foot-thick zone in the outcrop indicate that both data sets are log normally distributed and have similar frequency distribution functions. 2 refs., 4 figs.
