WesternGeco Non Seismic Methods - EM

Integrated results interpretation

Exploit the power of the Petrel 3D canvas and overlay the spatial distribution of the resistivity on the seismic section of volume. Enrich your 3D scene with seismic horizons, wells and EM survey layout for a more comprehensive and better interpretation.

Plug-in Overview

The EM bundle extends Petrel by adding the processing and the modeling capabilities for magnetotellurics (MT) and controlled-source EM (CSEM) methodologies. The data navigation and pre-conditioning features are optimized and suitable for large scale surveys. The plugins enable the integration of EM data with geological knowledge, seismic and well logs.
