What is GeoModeller?
GeoModeller is a software tool for 3D geological modelling. For building complex, steady state, 3D geology models - and performing forward & inverse geophysical modelling directly from solid 3D geology.
Comprising a Geological Editor, Drill hole & grids/meshes management, Forward & inverse geophysics modules to manage and interpret your entire exploration, geothermal or engineering project.
The geophysical modelling module of GeoModeller allows you to compute the gravity and magnetic response of your geological model, and refine the model further using stochastic inversion techniques.
- Implicitly constrains models with primary geological data (contacts & orientation data) together with drill hole intercepts
- Adheres to rule-based modelling of fault networks & relationships of the pile
- Interpolates 3D surfaces by a ‘potential field method’ which derives joint-constraints from contacts and orientation data.
- Implicitly models formations across fault planes
- 2D & 3D viewers
Drill hole & grids/meshes management
- Fully supports drill holes & attributed data
- Offers a range of interpolation methods including domain kriging (to mimic geology formation shape avoiding un-folding prior to kriging)
- 3D grids/meshes calculator
- 3D viewer and slicing tools
Forward & inverse geophysics modules
Using stochastic inversion techniques
- 2D profile modelling of gravity and magnetics and synthetic seismographs
- 3D forward modelling of gravity, magnetics (including remanence), full tensor gradiometry (FTG)
- 3D forward computation of temperature, vertical heat flow & geothermal gradient
- 3D litho-constrained stochastic geophysical inversion (gravity, magnetics, FTG or any two datasets jointly)
- Driven by comprehensive GUIs & wizards
- Modelling can commence from a GeoModeller model, or an imported lithology voxet
- Handles variable rock properties through look-up tables (probablity distribution functions) or custom voxets
- Browses to reference geophysical grids
- Comprehensive post-inversion products including quantified uncertainty of geology-geometry & rock properties
The GeoModeller inversion method is non-deterministic. Inversion continues beyond a satisfactorily low misfit level (referencing observed geophysics at set precisions) – exploring & keeping a range of allowable models, and presenting distilled statistics of these, in terms of probabilities of geology-geometries and rock properties.
