Res2DInv
Build more accurate Earth models with support for Full IP Decay
The latest Res2DInv release introduces new tools for reviewing, cleaning, and interpreting IP datasets, helping you separate earth signal from noise to build more accurate Earth models.
What’s new in 2026.1:
– Visualise the full IP decay curve for each measurement
– Flag noise or suspect data ahead of inversion
– Review profiles on a log scale with clear markers for negative values
– Examine the full decay for each individual IP value in the profile plot
– Clean data faster with slope filtering and auto-disable of negative gates
These updates help you work faster and more clearly, especially when managing large datasets or repeat workflows.

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.
