REDUCING THE MAGNETIC VISCOSITY EFFECT ON TEM SOUNDING DATA

https://doi.org/10.5800/GT-2021-12-3s-0548

Abstract

Siberian Traps magnetic viscosity affects and makes it difficult to interpret TEM sounding data obtained during oil and gas exploration in the south of the Siberian platform. In this paper, we present and discuss a method for decreasing magnetic viscosity effect on TEM data. The method is based on estimating magnetic viscosity contribution to the total transient response using TEM data measured with multi-offset arrays.
