DOI: 10.1007/s10706-019-00963-5
Abstract: Bender element (BE) is a useful seismic tool to predict the geotechnical soil properties using empirical correlations. However, there were uncertainties in the correlation equations which were not discussed in detail. In this study, the… read more here.

DOI: 10.1007/s11004-019-09830-8
Abstract: Characterization of discrete fracture networks is necessary for unconventional reservoir development, as they control the flow of fluids toward the hydraulically fractured well. Interpretation of microseismic data provides information about the discrete fracture network in… read more here.
