Phase 2 initial borehole drilling and testing at IG_BH04/05/06, Ignace area: WP05 data report - geophysical well logging for IG BH06

The Phase 2 Initial Borehole Drilling and Testing at IG_BH04/05/06 project in the Ignace area of Ontario, is part of the Phase 2 Geoscientific Preliminary Field Investigations of the NWMO's Adaptive Phased Management (APM) Site Selection Phase. This project involves testing of deep borehole IG_BH04 and the drilling and testing of deep boreholes IG_BH05 and IG_BH06 in the Ignace area within the identified Potential Repository Area (PRA). The work comprises a total of seven work packages and will be carried out by a team led by Golder Associates Ltd. (Golder) on behalf of the NWMO. The IG_BH06 program is described in the Borehole Characterization Plan (BCP) for IG_BH06 (Golder 2021a). This data report describes the methodology, activities, and reporting for Work Package 5 (WP05): Geophysical Well Logging for IG_BH06. This report describes the methodology, calibration/verification, acquisition and processing of the borehole geophysical data. Information from borehole geophysical logging will be used to help assess the local thickness of potentially suitable rock units, the geophysical properties of the rock units at depth, and the presence and types of structural features at depth. The geophysical logging provides high-quality, and high-resolution estimates of rock properties including engineering, lithological, hydrogeological, and structural properties. (author)
