    Non-Seismic Data Acquisition and Processing

    Various kinds of geophysical data are available. They are usually separated into Seismic and Non-Seismic data. Seismic is, without any doubt, the main method used in the oil and gas industry. But Non-Seismic data (gravity, magnetics, electrical, electromagnetics, spectral, etc.) is the main source of information in shallow subsurface applications (engineering, mapping pollution, archaeology, etc.). It is also used at the early reconnaissance of hydrocarbon plays and in mapping prospects below salt.

    After discussing the context within which non-seismic methods play a role, the course will deal extensively with gravity, magnetics, electrical and electromagnetic methods. The theory will be explained and applied in numerous exercises to enhance the learning. Also, participant presentations and subsequent discussion are a major part of the course.
