In-Situ Dynamic Elastic Moduli of Mesaverde Rocks and a Comparison with Static and Dynamic Laboratory Moduli
This report focuses on tests performed on sandstones and shales from four wells in the Mesaverde formation. A previous document showed a comparison of the static and dynamic laboratory moduli. This document describes how field velocity logs were used to derive field dynamic moduli. A 3-way comparison was performed for these stiffness properties; the results show no agreement between the three sets of values. Differences between dynamic stiffness coefficients from the field and the laboratory exceed 200%; differences between static and dynamic coefficients range up to 600%. In turn, this indicated that a reliable method of estimating mechanical rock properties for hydraulic fracturing design has not been established, and that such a task should be pursued. 23 refs., 14 figs., 3 tabs. (ERA citation 11:015665)
