Magnetotelluric and Controlled-Source Electromagnetic Methodologies for Geoscientists
The Magnetotelluric (MT) and Controlled-Source Electromagnetic (CSEM) methodologies course is meant to introduce a geoscientist to the physical concept of each electromagnetic measurements and to illustrate the added value of the integration of these methodologies for a better understanding of specific geologic targets in both marine and land environments.
This course has also the objective to introduce the features of the Petrel Magnetotellurics and of the Petrel Controlled-Source EM plugins for the display, pre-conditioning, QC, modeling and interpretation of electromagnetics data.
The course includes a theory section intended to present the physical principles of each electromagnetic discipline and a basic introduction to the data acquisition process.
Most of the course is focused on the introduction of the EM data processing and interpretation workflow through the presentation and the explanation of the Petrel plugins features by means of practical examples.
The explanation of the software features is interleaved with practical exercises to allow the attendees practicing with the Petrel plugins.
