Overview of Magnetotellurics for Oil & Gas Exploration

Magnetotellurics (MT) measurements are flexible, low-impact ground geophysical methods employed to produce 2D and 3D electrical resistivity earth models.  The natural source MT signal provides accurate data from near surface to 10+ km depth.  MT has particular applicability for reconnaissance in advance of seismic surveys and to provide electrical resistivity and geometrical information to enhance seismic interpretation, particularly in terrains where seismic data quality has been degraded.  Quantec's Spartan MT technology is an advanced approach to lithologic mapping offering significant benefits for oil and gas exploration.  In this page we describe Spartan MT and its application in exploration.

Applications of Magnetotellurics

Key applications of MT in oil and gas exploration include:

  • Reconnaissance of prospective areas to delineate basin limits and depths, useful for planning of subsequent seismic surveys.
  • Map basement variations beyond the reach of seismic surveys.
  • Provide 2D and 3D resistivity models as an aid to seismic survey interpretation.
  • Map electrical resistivity variations of the major stratigraphic units in the basin.
  • In some circumstances, provide direct detection of hydrocarbons.
  • Map salt domes, major structural deformations, high angle structures and lithologic variations.
  • Provide lithologic and structural information in areas where seismic data is degraded or unavailable due to: volcanic cover, population centres, nature preserves, extensive river tributary systems, rugged topography or difficult access.
