  • Res3dinvx64 Starter is in addition to the limitations of RES3DINVx64 Basic also limited 1000 electrodes and 5 inversion iterations.

  • Res3dinvx64 Professional supports 3-D time-lapse inversion. Res3dinvx64 Professional can access up to 256GB RAM and the maximum mesh size depends on the computer RAM. With 128GB RAM, it supports up to about 10 million nodes.

  • Res3dinvx64 Enterprise, in addition to Professional, also supports

    • Subdivide large mesh into segments. Possible to perform larger inversions using the same computational resources. (for now IP inversion is only possible using the linear perturbation method when using the subdivision option)

    • Support for vector array datasets, such as the IRIS Full Waver system.

    • Calculation of Volume of Investigation (VOI).

All versions support non-rectangular survey layouts (including inclined boreholes) using the arbitrary electrodes data format, and I.P. inversion using the complex resistivity method.

  • Aarhus Workbench Essentials can import inversion results from Res2DInv/Res3DInv for visualization on GIS interface, sections, depth slices, 3D viewer and PDF reports. It is also possible to import borehole lithology logs and geophysical logs.

However, the software version provided, and updates downloaded up to one year after the software purchase, can still be used indefinitely if the user chooses not to upgrade.

Quotes and payment can be made in USD and other currencies.

Res2Dinv and res3Dinv will run in demo mode if no license key is entered. Res2Dinv is limited to 84 electrodes in demo mode and res3Dinv is limited to 200 electrodes. No technical support is provided for demo users.
