Handbook of log evaluation techniques for carbonate reservoirs

Asquith, G. B.

This pithy and powerful methods manual provides the insights, concepts, and quantitative techniques to conduct log analysis on carbonate reservoir rocks. Asquith provides formulations for determinations of 1) cementation exponent, 2) bulk volume water, 3) production ratio index, 4) moveable hydrocarbon, 5) microporosity, and 6) fracture porosity. To accomplish these, all standard logs are used as well as some others, including dielectric constant logs. Importantly, each calculation and log type used is explained in terms of the interactions of the emissions, rocks, and fluids, and each is cast in the context of a case study example. These examples include the Pennsylvanian Canyon Reef, Horseshoe Atoll, Midland Basin, Texas; Ordovician Red River Fm., Williston Basin, North Dakota; Devonian Zama Reef, Alberta Basin, Canada; Pennsylvanian Lansing-Kansas City Formations and Lansing Limestone, Anadarko Basin, Kansas; and Jurassic Smackover Fm., Gulf Coast Basin, Arkansas. The individual techniques presented in this volume are not just stand alone. Asquith demonstrates how several can be combined for more advanced evaluations of saturations and moveable fluids. This book should be used by all new, up and coming industry petrophysicists and reservoir describers as a primer for carbonate log analysis.
