Geophysical Modelling

Modelling and inversion of geophysical data is undertaken in a 3D environment using GoCad with Mira extensions.

Inversion work utilises both VPMG and UBC software running on a highly parallelised server platform. Modelling techniques include:

  • Regional removal using a deep “basement model”
  • Basic heterogeneous unconstrained inversion of (often large) airborne geophysical datasets. These results provide a useful first-pass model  and interpretation aid;
  • Constrained geometric inversion including available/mapped geology, physical property data and drillhole data;
  • Combinations of constrained and unconstrained models to refine geological models between drill holes.
