res3dinv 3.19.2

2D and 3D inversion software for processing induced polarization data. It uses the fast least squares method to invert the data, greatly reducing the time required for inversion while ensuring the quality of the inversion results, making it suitable for Wenner（ α、β、γ）、 Dipole Dipole, (AB MN Rolling), Monopole Dipole (A-MN Rolling, MN-B Rolling, A-MN Rectangle), Dipole (A-M Rolling), Schlumberger（ α Various devices such as 2-arrangement and quadrupole sounding rolling can process ground measurement data, as well as underwater measurement data and cross hole measurement data. It is currently a highly recognized IP data inversion software internationally.

Comparison between Smooth Inversion Method and Robust Inversion Method


Figure 1-a shows a composite model with a fault block (resistivity of 50 ohm. m) at the bottom left and a small rectangular block (1 ohm. m) at the bottom right. The surrounding medium resistivity is 10 ohm. m, and a test dataset was generated using the Wenner device to generate a simulated cross-sectional view of the apparent resistivity; Figure 1-b shows the conventional smooth constrained least squares method for inversion of quasi cross-sectional images, with the boundaries shown as gradient boundaries; Figure 1-1c shows the pseudo cross-section of the Robust inversion method. In contrast, the model boundary obtained by the Robust model inversion method is clearer.
