NGI into airborne EM surveys
Date: 5/20/2008
Onshore geophysical activities at NGI are increasing: As an advisor to DNO International ASA, NGI is planning, supervising and interpreting an Airborne Electromagnetic (EM) survey over an area of some 2.000 km2 in central Mozambique.

The emerging market on onshore EM oil and Gas exploration, boosted by the huge success of marine EM over the last years, is a vast potential for well established, as well as new and innovative deep penetrating EM techniques. NGI's expertise in geophysics has focused on various methods and equipment for mapping offshore reservoirs and detecting oil and gas. This knowledge is now being used airborne.
"Given the expected geological background and target properties, we choose a time domain helicopter borne EM system", says NGI's Dr. Andi Pfaffling. "The AeroTEM IV instrument provides earth magnetic field intensity, surface concentrations of Potassium, Uranium and Thorium and finally EM data in an extensive complexity which lead to subsurface resistivity sections via sophisticated inversion algorithms."

Dr. Andi Pfaffling presents a special session on AEM hydrocarbon prospecting at the 5th International Conference on Airborne Electromagnetics 28-30 May 2008 in Helsinki Finland.
