Joint Inversion of Helicopter-Borne Electromagnetic Data Using Marquardt's Algorithm

Abstract:

The inversion stability of geological data can be enhanced by increasing the number of observation data or improving the accuracy of it. For the purpose of increasing the input parameters, the joint inversion algorithm based on Marquette’s method is introduced to the helicopter-borne electromagnetic system. Since double parameters of both the horizontal coplanar and vertical coaxial coils were taken into account, the stability of the inversion process is greatly improved. In fact, the joint inversion algorithm not only enhances the inversion’s stability, but also overcomes the limitation of the inversion with each single device in order to make the result closer to the real resistivity characteristics
