During the five years since the last Exploration07 Conference, a number of important developments took place in the area of quantitative data interpretation techniques. In this presentation, I provide a brief review of new developments in 3D potential-field inversions achieved primarily since the Exploration07 Conference. I will focus on the advances in three areas: (1) inversion of complex magnetic data sets affected by strong remanent magnetization and self-demagnetization effects; (2) inversion of multiple-component gravity gradiometry and magnetic gradiometry data, and borehole gravity data; (3) algorithmic and computational techniques for enabling and accelerating the solution of super-large scale problems on both district scales with high resolution data, and on regional and global scales. It is hoped that the materials will be beneficial to a broad audience of practicing geophysicists in the mineral and petroleum industry.
