KEYNOTE ADDRESS: 3D EM INVERSION: WHERE ARE WE AND WHAT'S THE ROAD AHEAD?

摘要

Recent advances in computing hardware and numerical optimisation have led to major improvements in our capabilities to invert 3D electromagnetic data. Today, most frequency and time domain data sets can be inverted, irrespective of whether the observations/transmitters are in the air, on the surface or in boreholes. The remaining challenges are therefore focused on further development of these procedures to obtain high quality results in a shorter time and to design appropriate surveys that lead to the desired resolution.
