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

Design, fabrication and deployment of the AutoSonde for acquisition of total count natural gamma, magnetic susceptibility, resistivity and IP (induced polarisation) data from conventional diamond drilled boreholes.  The AutoSonde passes through the inside of the drill rods and protrudes beyond the drill bit.  Physical property data is acquired as the driller recovers the drill rods.  Extensive field testing has shown results consistent with conventional wireline data but at higher resolution.
