Abstract
(EN)



Method for removing effects of shallow resistivity structures in
electromagnetic survey data to produce a low frequency resistivity anomaly
map, or alternatively imaging resistivity structures at their correct depth
levels. The method involves solving Maxwell's electromagnetic field equations
by either forward modeling or inversion, and requires at least two survey data
sets, one taken at the source frequency selected to penetrate to a target
depth, the other a higher frequency able to penetrate only shallow depths.
