AutoShuttle on site at the Brukunga Drilling Research and Training Facility.

Design, fabrication and deployment of the AutoShuttle for acquisition of spectral natural gamma data from conventional diamond drilled boreholes.  The AutoShuttle sits within the core barrel assembly and continuously acquires data during drilling.  Both the AutoSonde and AutoShuttle can be deployed by the driller, removing the need to and expense of mobilising a separate wireline logging crew and risk of losing the hole prior to logging.  Both operate autonomously meaning there are no wires connecting the tool to the surface.  All data captured are transmitted wirelessly to a handheld device on return to the surface.  These technologies will both improve the productivity of conventional diamond drilling and were a stepping stone to developing similar downhole sensing technologies for coiled tubing drilling.
