Remote Voxi Induced Polarization (IP) Workshop This instructor-led remote course will cover key concepts behind Induced Polarization: data import, visualization, processing and various quality control tools

In this course participants will learn to plot and visualize resultant data as pseudo-sections, work with the data in 2D and 3D.

The second part of the course uses hands-on activities to demonstrate key considerations for data preparation, testing acquisition hypotheses with forward modelling, auxiliary parameters for inversion setup, best practices for constrained and unconstrained inversions. Participants will have the opportunity to create models during and after the workshop using VOXI IP and Resistivity Earth Modelling.

Registration includes complimentary access to everything you need for the course, including Oasis montaj, IP extension and a subscription to VOXI Earth Modeling.


2 x 4hr sessions (run over 2 days = 8hr)

Maximum Capacity:

6 Participants
