3D-GEO uses experienced associates and partner organisations to conduct Potential Field interpretations. This specialist work requires experts with substantial experience in data acquisition, processing, and interpretation. Typically, after data QC, sophisticated inversion methods such as VPmg constrained-inversion are used to determine the magnetic properties and density of heterogenous basement and sediments. The geometry of basement contacts and any higher-level volcanics and intrusions are derived. Edge effects must be compensated for and calibration to nearby basement outcrop, seismic reflections and well penetration is a useful QC. Software such as GoCad can be used in gravity and magnetic inversion modelling and visualisation. Outputs include structural element maps, depth to basement models and large-scale basin geometries for burial and thermal histories.
