About VOXI Earth Modelling
An introduction to VOXI Earth Modelling, containing brief descriptions of the terminology used in the VOXI environment and a video demonstrating the VOXI Viewer.
Preparing Data for Inversion
Best practices around the necessary data required for perform your first inversion and a video demonstrating the data preparation steps.
Adding Data for an Unconstrained Inversion
Add the data necessary to perform an unconstrained inversion, including assigning error values, removing the background trend and modifying the mesh parameters.
Running the Unconstrained Inversion
Upon adding data to the VOXI session, run the unconstrained inversion.
Exporting Inversion Parameters
Export the parameters used in your inversion so you can re-use and modify as needed for later sessions or for reference.
Exporting and Inspecting Inversion Results
Export the unconstrained inversion results as a Geosoft Voxel file to share with others or to integrate with other data in the 3D Viewer, or alternatively, display the results in a 3D map.
Comparing Inversion Results to Data
Compare the predicted data from the inversion results to the observed data in Oasis montaj in order to assess the quality of the result.
Building Geologic Models using NODDY
Model more realistic geological scenarios using NODDY - a geological model building tool - for use in VOXI Forward Modelling.
Extending a Model - Adding and Adjusting Data
Add and adjust the data to run a forward model by introducing padding to compensate for the regional effect that contributes to the potential field response.
Extending and Running the Forward Model
Upon adding and adjusting the data, run the forward model, continue to pad the active volume and re-run the forward model.
Extending a Model - Exporting and Viewing Results
Export and view the predicted response database, and compare the results from the forward model calculations in the 3D Viewer.
Define the input files needed to create a new VOXI session from a Voxel and add data to the session before forward modelling.
Building a Model
Build a simple "Half Graben" model based on a normal fault.
Modifying the DEM and Padding the Active Volume
Modify the DEM as needed and pad the active volume to minimize edge effects during modelling.
Running the Forward Model
Having supplied the voxel model defining the area of interest, added the database containing the data channel to be populated, selected a DEM and modified the model mesh, run the forward model.
Exporting and Viewing Modelling Results
Export the predicted response database and as well, grid and view the forward calculated data.
Creating Constraint Voxels
Use voxel math and create an upper bound voxel model for the Upper Bound Constraint Inversion and as well, generate the gradient weighting constraint voxel models.
Iterative Reweighting Inversion
Define a reweighting (IRIF) model constraint in VOXI and learn best practices around Iterative reweighting inversion (IRI), including sharpening.
Applying Drillhole Constraints
Use the drillhole weight model building tool to easily integrate drillhole data into an VOXI inversion and create constraints.
Adding Data - Upper Bound Constrained Inversion
Add the data necessary to perform an upper bound constrained inversion, including assigning error values, removing the background trend and modifying the mesh parameters.
Adding Data - Gradient Weighting Constrained Inversion
Add the data necessary to perform an gradient weighting constrained inversion, including assigning error values, removing the background trend and modifying the mesh parameters.
Applying Constraints - Upper Bound Constrained Inversion
Apply the Upper Bound constraint to the VOXI session prior to running the inversion.
Applying Constraints - Gradient Weighting Constrained Inversion
Apply the upper bound and gradient weighting constraints to the VOXI session prior to running the inversion.
Running the Upper Bound Constrained Inversion
Upon adding data to the VOXI session and applying the constraint, run the upper bound constrained inversion.
Running the Gradient Weighting Constrained Inversion
Upon adding data to the VOXI session and applying the constraint, run the gradient weighting constrained inversion.
Exporting Results - Upper Bound Constrained Inversion
Export the upper bound constrained inversion results as a Geosoft Voxel file to share with others or to integrate with other data in the 3D Viewer, or alternatively, display the results in a 3D map.
Exporting Results - Gradient Weighting Constrained Inversion
