This workshop is suitable for geophysicists/geologists/engineers interested in resistivity and induced polarization (ERT/IP) surveys and students/staff at academic institutions involved in research on the ERT/IP method, having a basic knowledge of geophysical survey methods.

Level: Beginner/Intermediate

The ERT/IP method is widely used for hydrological, environmental, engineering and mining surveys to map the subsurface resistivity and chargeability. In this workshop, we will cover the basics of the ERT/IP method and go through all steps from processing and inversion of data examples to visualization of model results. This course uses hands-on activities to demonstrate importing data, removal of bad data points, data inversion, model discretization, damping/smoothing settings and creating visualizations of inversion results. Participants will also take away an overview of current best practices for resistivity and IP data processing and inversion. The course will be using the new 2023 version of Res2Dinv with a completely new user interface and the known Res3Dinv. Registration includes complimentary access to everything you need for the course, Res2DInv and Res3DInv complementary licenses.

What will the course cover?

  • Introduction to Res2DInv and Res3DInv
  • Basic theory of IP and resistivity surveys
  • Basic overview of inversion methods
  • Working with .dat files and related conversions
  • Processing 2D and 3D time-domain and frequency-domain data from dipole-dipole, pole-dipole, pole-pole, and gradient survey configurations
  • Handling different instruments and arrays
  • Performing interactive quality control
  • Adding georeferencing and topographic information
  • Plotting model and data pseudo sections
  • Inversion settings and options
  • Adding prior information
  • Troubleshooting problematic inversions
  • Display sections

Hands-on exercises at the workshops will be sent to participants along with license information before the course. For hands-on exercises, please bring your own laptop.
