User Manual
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.


  • Petrel 2016.x
  • Petrel Geoscience Core


  • Processing
    • Data analysis/QC
    • 1D/2D/3D forward modeling and inversion
  • Interpretation
    • Delineation of structural features at basin/regional scale
    • Ore bodies and geothermal reservoir identification

Key Features

  • Data preconditioning prior to the inversion such as muting (in manual or batch fashion), decomposition and resampling
  • Visualization and extraction of EM data attributes in the form of maps and pseudo-sections
  • Enhanced 2D/3D model building and population through customized model geometry and resistivity distribution editor
  • Interactive 2D forward modeling and inversion multithreaded code
  • Front-end for 3D EM forward modeling and inversion HPC code
  • Data QC and pre-conditioning: display and edit raw soundings; create maps and pseudo-sections from EM data attributes to facilitate the QC process.
  • Modeling: perform quantitative data interpretation through 1D and 2D forward modeling and inversion.
  • Integration: complement your G&G knowledge with EM data for a more comprehensive subsurface characterization in a unique platform.
