Geosoft has added induced polarization (IP) and resistivity data inversion to its VOXI Earth Modelling 3D inversion software service. The new toolset is available as part of Geosoft’s 9.1 software update released this week.
RE2CAP is free software (Freeware) that was designed and developed i for the area of electrical engineering. RE2CAP is a graphical tool for a two-layer soil electrical resistivity modeling by the inversion of parameters by numerical methods. The results obtained can be used as a basis for grounding designs. 3D electrotomography for resistivity and IP. Forward modeling and inversion. Land, water, crosshole. Forward modeling and inversion. 3D gravity and magnetic. Forward modeling and inversion. 2D Self-potential. Forward modeling and inversion. In this case you should use lastest version of software which worked properly.
Geoscientists are now able to create detailed 3D models of conductivity and chargeability from IP and resistivity survey data with VOXI. The resulting models can assist in interpreting and targeting regions for mineral and environmental applications.
VOXI’s full featured and modern approach to 3D modelling of IP and Resistivity data includes superior defaults and parameter options that support all electrode configurations and a full suite of measurements. A 3D algorithm is utilized for forward and inverse calculations of time domain and spectral IP and resistivity data.
Multidisciplinary geoscientific data and models can be incorporated into the inversion using VOXI 3D constraint building tools. The models can be integrated seamlessly with geophysical or geological interpretations within Geosoft’s geoscience platform, Oasis montaj.

AGI EarthImager 3D - New Resistivity Inversion Software
EarthImager 3D owners, check the EarthImager User Group page for newer version download.
AGI is proud to introduce the new EarthImager 3D resistivity and IP inversion software. This software inverts resistivity and IP data acquired with electrodes arranged in boreholes and/or on the surface and presents a 3D volume of inverted resistivity data with advanced volume rendering technique. The final resistivity or IP image-volume can be rotated in any orientation, zoomed in and out, and translated to anywhere inside the image window in order to see the volume of interest in detail. Colors representing areas of less interest can be made transparent so that the shape of a pollution plume, for example, can be visible. With EarthImager, 3D resistivity inversion can be as easy as two steps: Read Data and Start Inversion with only a few mouse clicks.

You can test AGI EarthImager 3D yourself by downloading the demo. It is fully functional except some features like printing and saving has been disabled and the maximum iteration number is limited.
Some of the features of the EarthImager 3D are:
More features will be added continuously.
AGI EarthImager 3D Video
(NOTE: Requires Windows Media Player to be installed! The default player for video clips must be set to Windows Media Player! If you use Real Player then you cannot view the video clip!) Click the play button to view video (may take some time to load on slow connections). Tip: You can drag the position button to any scene for detailed study. To play the 3D video, increase your hardware acceleration to the FULL level if no video shows up.
Screenshots with explanations:
Figure 1: The left image shows the arrangement of the electrodes, in this case, in 5 boreholes. The electrodes can be arranged both in boreholes and/or on the surface. The right picture shows the scatter plot of measured apparent resistivity. By left clicking on one data point in this picture the corresponding four active electrodes are showed as red electrodes (current) and blue electrodes (potential), and the picked data point as a black dot. Figure 2: The electrode arrangement on the left side can be rotated or turned in any way so that electrodes further back, which are blocked from view by electrodes closer, can be seen. The inversion is started by clicking on the green button with the arrow. ![]() 3d Resistivity Inversion Software Downloads For ComputerFigure 3: When the inversion is started a crossplot of measured versus calculated apparent resistivities is shown to the left. Ideally all of the dots should end up on a 45 degree line for noise-free data and error-free numerical modeling. The right image shows a 3D volume of inverted resistivity. Resistivity inversion is an iterative process. These two images will update at the end of each iteration. Figure 4: At the end of inversion, the user can customize the data range (min and max), plot scale (linear or logarithmic), and color transparency or opacity (Figure 5 below) from the Color and Contour Properties window. Figure 5: The transparency of each color can be changed by dragging or clicking anywhere inside the grid. A color with 0 opacity would be totally transparent and a color with an opacity value of 1 will be solid. By manipulating the opacity, a user can investigate different volume of interest inside the imaging volume. Figure 6: The maximum resistivity value is set to 50 ohm-m, and resistivity values below 10 ohm-m (blue and green colors) are made transparent. 3d Resistivity Inversion Software Downloads FreeFigure 7: These dynamic slices are a powerful tool for interactive data interpretation. Any of three slices may be turned on or off. Any slice can be moved along the axis to sweep through the entire volume in search for anomalies. A left mouse clicking on a slice would reveal the x, y, z coordinate and corresponding resistivity value. In addition, EarthImager also shows a stack of four static slices in either X, Y or Z orientation.
