Porosity and Permeability of Unconsolidated, Upper Miocene Sands From Grain-size Analysis

Norman R. Morrow, John D. Huppler, A. Barlow Simmons, III

ABSTRACT

Core analysis data for 78 cores taken from Upper Miocene sands were used to develop correlations between porosity and permeability of unconsolidated cores and their grain-size analyses. The grain-size distributions of these cores are best described mathematically by the Rosin-Rammler equation. The two parameters of this equation together with two other easily measured parameters of grain size were grouped to give correlations with porosity and permeability. Porosities were correlated to within 2 percent for 80 percent of the samples and permeabilities were correlated to within a factor of 2 for 70 percent of the samples.
