Magnetometry is a commonly used and highly effective approach for locating abandoned wells and buried pipelines and buried debris in legacy and operating oil and gas fields. Unfortunately, the magnetic data do not provide any insight about subsurface contamination. Electromagnetic imaging (EMI), on the other hand, is an ideal method to delineating areas within the surface that have been impacted by leaks, spills, and the residue left behind from normal oil field operations. When applied in tandem, magnetometry and EMI are no less than the dynamic duo of geophysical subsurface characterization.
