The primary objective of this research is to develop methods for better describing the three-dimensional geometry of carbonate reservoir flow units as related to conventional or enhanced recovery of oil. Detailed characterization of geologic facies and rock permeability in reservoir-scale outcrops of the Permian San Andres Formation in the Guadalupe Mountains of New Mexico will provide the key data base. In addition, outcrop coring and logging will provide a data set directly comparable to the subsurface reservoirs. To this end a coring program was designed to sample the cyclic outer ramp strata of the San Andres on the Algerita Escarpment. The location of the core holes was not immediately coincident with the crop sampling program in Irabarne Canyon but rather was from Lawyer Canyon (NE 1/4 OF SW 1/4, SECT 21, T23S R20E; fig. 1) where an extensive program was already underway to describe reservoir heterogeneity in the upper San Andres interval. Core material from the lower half of these cores is of outer ramp facies comparable to that studied in the Irabarne Tank area.
