Fast, full featured geophysical inversion modelling
Generate 3D inversions and forward models
Invert geophysical data and create quantitative 3D models of the earth to further understand the structure and processes beneath the surface. Calculate the response of a given physical property of a user defined 3D voxel model with VOXI forward modelling tools.
Build and constrain models
Use the Model Builder to incorporate supplementary geological, geophysical and geochemical information. Automatically apply these models as constraints to the inversion using Parameter and Gradient reference models; Upper and Lower bounds; Parameter and Gradient weightings; Active Model; and Reweighting Model. The defaults are auto-populated and the math is applied automatically, to make creation of constraints easier and allow more time for interpretation.
Model gravity gradiometry data
VOXI supports inversion and forward modelling of Gravity Gradiometry Data to yield a detailed 3D model of the rock density. The resulting detailed density model can be used to interpret and to target regions for potential oil, gas and mineral deposits. Generic vertical gravity gradient data is supported as well as direct import of two common data types: Falcon AGG data and Bell Geoscience/ARKeX LM FTG data.
Model frequency domain EM data
With VOXI you can invert frequency domain horizontal coplanar configuration electromagnetic (EM) data to produce a voxel conductivity model. You can then integrate this conductivity model with your gravity and magnetic inversions into a geophysical or geological interpretation in Oasis montaj. The FDEM inversion is based on 1D inversions interpolated along and between lines, suitable for airborne frequency domain systems such as Dighem or Resolve.
Model the 3D magnetization vector
Traditional susceptibility inversions assume that subsurface magnetization is in the direction of Earth’s magnetic field. More often than not, this assumption is false and can yield inaccurate inversion results. Magnetization Vector Inversion (MVI) is a method that solves for both magnitude and direction. The results are not limited by erroneous assumptions and have been shown to coincide more closely with known geology than traditional susceptibility models.
Sharpen contacts with Iterative Reweighting Inversion Focusing
Iterative Reweighting Inversion Focusing (IRIF) takes a smooth earth model and uses it as a reweighting constraint when running a new inversion of the same data. It is used to model sharper contacts in the inversion result, providing more refined targets. IRIF is automated, saving processing time so that your results are available sooner.
Model IP and Resistivity data
VOXI supports inversion and forward modelling of IP and resistivity data to yield a detailed 3D model of conductivity and chargeability. The resulting models can be used to interpret and target regions for mineral and environmental applications.
