Several semester's worth of study by numerous graduate students during R. M. Slatt's Geologic Reservoir Characterization classes at Colorado Shool of Mines (CSM) have helped develop and refine our ideas of stratigraphic and structural compartmentalization; however, final interpretations are our own. The authors also wish to thank colleagues Robert Thompson, Ramona Graves, Craig VanKirk and their students in the Petroleum Engineering Department of CSM, and Thomas Davis and Robert Benson in the Geophysics Department at CSM for participation in this joint research effort; Knut O. Bjorlykke of the University of Oslo, Norway for providing petrographic analyses; Hugo Araujo for conducting permeability measurements; Steven Drake, Sandra Mark, and Vickey Sare for assisting with computer graphics; Said Al-Maskari for identifying trace fossils; Kay Waller of the Denver Earth Resource Library for allowing access to log files; and Dwight's Inc. for providing the CD-ROM data. The pressure decay permeameter is housed in the Department of Petroleum Engineering at CSM. The research presented here was part of a larger project on Reservoir Compartments and Heterogeneity, funded through the Department of Petroleum Engineering at CSM by the Department of Energy Grant No. DE_AC22-93bc1489.
