Intrepid Geophysics develops software and provides services for potential field geophysics. It has carved out a strong reputation in geophysical processing and interpretation, and software development. 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. Geological Editor -Implicitly models 3D surfaces constrained by primary geological data (contacts & orientation data together) and/or drill hole intercepts. -Adheres to rule-based modelling of fault networks & relationships of the pile. 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 of gravity and magnetics (separately or 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.
