The Reliability of Core Data as Input to Seismic Reservoir Monitoring Studies

Abstract

Abstract There is a potential for improving the reliability of standard core tests for seismic monitoring studies. A primary concern is to quantify and correct for core damage effects, which significantly enhance the stress dependency of wave velocities. Careful laboratory procedures and modeling efforts may reduce such effects. However, no simple procedure is currently available to eliminate this problem. The use of simplified laboratory test procedures, in particular application of an inappropriate effective stress principle, may lead to erroneous interpretations.
