In-Situ Dynamic Moduli of Mesaverde Rocks Compared to Static and Dynamic Laboratory Moduli
This paper focuses on tests performed on sandstones and shales from four gas wells in the Mesaverde formation. A previous document showed a comparison of the static and dynamic laboratory moduli. This publication describes how field velocity logs were used to derive field dynamic moduli. A 3-way comparison was then 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 indicates 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., 6 figs., 3 tabs. (ERA citation 11:029250)
