Key geophysical logs and the FMI image of the 872–882 m MD fault core. The geophysical logs denote the lithology (GR and Vsh logs) and porosity (PHIE, RHOB, NPHI, and RT logs). The two most fractured intervals within the fault core are 872–874 and 881–882 m MD. These two intervals developed in the metasandstones (low GR) with high porosity (low RT, low RHOB, and high NPHI values). The attitude of the bounding fault planes at 872 and 882 m MD is around N40–50°E/45–55°NW
