摘要

There is a potential form improving the reliability of standard core tests for seismic monitoring studies. A primary concern is the ability to quantify and correct for core-damage effects, which sig- nificantly enhance the stress dependency of wave velocities. This problem is most relevant for relatively low-strength rocks cored in high-stress environments. We have used synthetic sandstones formed under stress to perform a systematic study of stress- release-induced core-damage effects. The results show that careful laboratory procedures and modeling efforts may reduce core dam- age effects.
