RES2DINV & RES3DINV bring users advanced data processing and inversion software toolkits for resistivity and induced polarization (IP) data processing and inversion. It supports the automatic inversion of underground three-dimensional (3-D) apparent resistivity models using data obtained from three-dimensional electrical exploration.

Through simple operations, you can immediately start using three different terrain modeling techniques and complex resistivity methods for high-density resistivity data inversion and induced polarization data inversion. It complies with standard rules and regulations, is easy to operate, and improves productivity. It perfectly supports conventional arrays as well as unconventional electrode arrays!

1. Supports traditional arrays such as Wenner, Wenner-Schlumberger, dipole-dipole, pole-dipole, pole, multi-gradient; and unconventional arrays such as offset pole-dipole arrays.

2. It can be used to process surface measurements, cross-hole measurements, and water measurement data of surface or bottom electrodes.

3. Invert IP data using complex resistivity methods.

4. Supports datasets of up to 85,000 readings and 9,500 electrode positions on a computer with 8 GB of memory. 32GB of memory supports up to 130,000 readings and 11,000 electrode positions.

5. Supports parallel processing on multi-core CPUs.

6. Many inversion techniques for different geological environments and survey configurations. This includes smooth (L2) and blocky (L1) inversion options, sparse inversion techniques for very long survey lines, and terrain modeling using the finite element method. Automatic determination of damping factors in smooth constrained least squares inversion methods using the L-curve method.

7. Calculate model resolution to assess model reliability.

8. The RES3DINV program overcomes the limitations of 2D inversion models and can combine data from different 2D survey lines into 3D datasets.

9. Output of results in common Geosoft XYZ and Golden Surfer formats.

10. Most resistivity instruments have software conversion programs that convert field datasets to the data format used by the program.

11. Support 64-bit Windows XP/Vista/7/8/10.
