Elastic Properties of Fault Core Samples Using Digital Rock Physics: Insight Into Seismogenic Fault Characterization
Available to Purchase
Paper presented at the SPWLA 22nd Formation Evaluation Symposium of Japan, September 29–30, 2016
Paper Number: SPWLA-JFES-2016-H
... Abstract To understand characteristics of deep seismogenic faults in the plate convergent margins, we used P- and S-wave velocities (Vp and Vs) of the digital rocks extracted from core samples of ancient plate boundary fault at Nobeoka in Kyushu, southwest Japan. We constructed 3D digital rock...
