EAGE E-Lecture: 3D Inversion of Magnetic Data Affected by Remanent Magnetization by Yaoguo Li

The inversion of magnetic data in the presence of strong remanent magnetization has long been a challenging problem, because of the unknown direction of the total magnetization that is the vector sum of the induced and remanent components. This E-Lecture presents three different techniques for tackling this problem: (1) direction estimation, (2) amplitude inversion, and (3) fuzzy c-means clustering magnetization inversion. Combined with the existing susceptibility inversion, these techniques form a tool kit that allows one to invert virtually any magnetic data set for the purpose of quantitative interpretation in exploration applications. In particular, the magnetization inversion provides a new opportunity both for imaging source configurations and for carrying out geology differentiation.

Thank you so much for such a comprehensive high-level presentation on the current state of the 3D Inversion of Magnetic Data. I am a geologist with bare minimum knowledge of geophysics. I could follow your clear explanation and now have an overview or high-level understanding of the 3D Inversion of Magnetic Data.
