Magnetic Data in the Oil & Gas Industry

Did you know ? 

In the upstream oil and gas industry, airborne magnetometer surveys can be used to detect a variety of near-surface hazards that are difficult to resolve in seismic data. Magnetic data will help identify fault zones, and orphaned well/drill hole and other iron-based infrastructure, associated with old and undocumented oilfield infrastructure.

Gas migrates toward the surface along naturally occurring faults and frequently, it gets trapped in shallow structures also difficult to see on seismic images. Drilling into a shallow gas pocket on the way to a deep target can result in huge unexpected costs for the operator. Operators need to know the hazards that exist, in order to design an efficient drilling program and an airborne magnetic survey is an effective way to identify those hazards.
