What’s new
Res2DInv
Export georeferenced grids. Control IP decay data.
This release focuses on improving how results move into Oasis montaj and Leapfrog, and how data is prepared for inversion. It makes it easier to bring crooked sections across with spatial alignment preserved, review IP decay data, and work with fixed regions and water surfaces before running an inversion.

System requirements
Important notes / unsupported setups
A modern PC with 4GB of RAM or more is sufficient for using Res2DInv, and inversions can be completed within a few minutes. Res2Dinv benefits from having more CPU cores, but it is more advantageous to have additional cores when upgrading from 4 to 16 CPUs rather than from 18 to 32.
Overall, Res2DInv is designed to be fast and efficient, and most modern computers easily meet the requirements.
Core system requirements
| Minimum | Recommended | |
|---|---|---|
| Operating system | Windows 10 (64-bit) | Windows 11 (64-bit) |
| Processor | 4 CPUs | 16 CPUs |
| System memory | 4 GB RAM | 8 GB RAM |
| Storage | 10 GB | 256 GB |
These system requirements may vary depending on the project and dataset size.
