o    In-situ water pressure (packer permeability) testing (WPT) must be conducted in all bores to assess the rock mass permeability;

o    In-situ stress testing must be conducted in selected bores using an agreed method such as the overcoring method;

o    The boreholes are oriented both vertically, and borehole advancement must be by non-core drilling in fill and soil and diamond core drilling in rock;

o    Borehole imaging by acoustic or optical means as agreed shall be carried out in all boreholes to measure defect orientations;

o    Pressuremeter Testing within shale units.
