Intrepid is a software suite with extensive capabilities in airborne, ground and marine: magnetics and gravity, plus multi-channel radiometrics data processing.  The stand-alone modules of Intrepid deliver comprehensive tools for QC, processing, filtering, interpretation and visualisation of potential field geophysics survey data.  Intrepid also provides capacity to process, interpret and grid airborne magnetic and gravity gradiometry data; both Full Tensor Gradiometry (FTG) and Falcon data.

Intrepid features include:

  • Superior gridding algorithms; Variable Density Gridding
  • All Intrepid tools support Full Tensors (Editor, Line/Grid Filter, Levelling, Gridding, Euler etc)
  • Automatic modelling outputs go straight into GeoModeller for building geology from geophysics
  • Handles multiple input datasets
  • File manager Statistics Tool is essential for QC
  • Comprehensive Land Gravity Networks tool

Advantages of Using Intrepid include:

  • Grid-merge employing state-of-the-art algorithms.
  • Gridding and variable density gridding plus Intrepid can handle multiple input datasets
  • Unique: Full Tensor and Falcon data handling capabilities
  • Automatic depth to source modelling
  • Solutions ready for 3D geophysical modelling in GeoModeller
  • Worming (multi-scale edge detection) plus implementing auto-calculation of dips straight from worms
  • Marine levelling
  • Comprehensive land gravity networks tool

GeoModeller - 3D geological modelling and geophysical inversion

GeoModeller is a software tool for building implicit 3D geology models from a diverse range of data sources, either rich or sparse in spatial terms (mapping, drilling, interpreted cross-sections, remote sensing images, depth-converted interpreted constraints from magnetics, gravity, seismic, EM, etc.)  It has a tightly integrated geophysical forward and inverse modelling capability.  The inversion method (gravity and/or magnetic) is stochastic in nature and litho-constrained. Multiple models are produced and can be assessed using statistical probabilities.

GeoModeller can use input data from a wide variety of sources.  For example, surface geological mapping, bore-hole logs and seismic horizons.  GeoModeller’s strengths lie in honouring coupled geological and structural observations, and employing rule-based modelling from the stratigraphic and fault network conventions.

GeoModeller contains several unique features:

  • Accepts primary geological observations to build the 3D geological model
  • Is geologically sensible, adhering to built-in geological rules
  • Easily accepts extra data, rapidly incorporating these and fully revising the model
  • Uses geophysical datasets to refine the model via inversion approaches (gravity and magnetic survey data) and forward modelling (seismic data)
  • Accurately models complex geological settings and elements (overturned fold limbs, complex faults / shear zones, intrusions, water columns and basement)
  • Its inversion process continues beyond a satisfactorily low misfit level (of observed versus computed parameters) – exploring a wide range of allowable models, and presenting these in terms of probabilities
  • Performs forward modelling of seismic data

In contrast to a CAD-style model, which uses shapes and surfaces to describe objects within a model, 3D GeoModeller is described in terms of:

  • a stratigraphic pile
  • geological contact points
  • geological orientation data.
