Modules: GeoModeller



GEOLOGY MODELLING Full 3D geology model-building including all input/output, editing, visualisation, advanced drill hole management, interpolation of drill hole attributes, 2D/3D grid/mesh visualisation & computation, geology & resource volumetrics, property optimisation. Forward Grav-Mag geophysics modelling in 2.5D & 3D. And forward prediction of synthetic 2D seismographs.

Main Add-on


FULL GRAV/MAG INVERSION Litho-constrained stochastic geophysical inversion. Including joint inversion of any number and combination from: gravity, magnetics, tensor grids of Grav/Mag, and component tensor grids of Grav/Mag. Litho-constraints are either directly from 3D geology (GeoModeller-Base) or linked to an imported starting lithology or property voxet. Also includes any combination (%) from Fixed Geology Property-Only inversion to Fixed Property Geology Geometry-only inversion. This module also includes 3D geothermal computations, and a micro-seismic events record viewer with a temporal filter.

Add-on to V4

CGAL Libraries

For building meshes of surfaces and volumes by triangular and tetrahedral elements, derived from implicit models from GeoModeller, exporting to various finite element mesh formats (some aspects of this support still under development in Beta GeoModeller v3.4)

Add-on to V4

Limited AEM module 1D inversion

Enabling: Load/interrogate your airborne EM survey data; Create geological sections for each line; Create a geology model and predict the 1D EM response; Review the predicted outcomes as log conductivity sections and 3D Point clouds of predicted resistivity/conductivity; Generate a request for a 2.5D inversion bureau service to be performed by Intrepid Geophysics for a fee (see below). Supports all common commercial airborne EM systems.
