This study compares cover thickness estimates from geophysical techniques acquired prior to drilling to preliminary results from the Coompana Drilling Program in the far west of South Australia. Prior to drilling, geophysical techniques consisting of magnetotellurics (MT) and reflection and refraction seismic were deployed to estimate the thickness of Cenozoic cover sediments at the proposed drill-sites. The estimates of cover thickness assisted with planning the Coompana Drilling Program and helped to de-risk the stratigraphic drilling by providing estimates of cover thickness.
