Laterally Constrained 1D-Inversion of 3D TEM Data

Abstract

A008 LATERALLY CONSTRAINED 1D-INVERSION OF 3D TEM DATA Summary 1 In this presentation we show that the interpretation of spatial densely sampled TEM data over 2D earth structures is greatly enhanced by inverting the data using the 1D-LCI algorithm (Laterally Constrained Inversion). In the 1D-LCI algorithm neighboring models are constrained laterally on layer resistivities and interfaces. Introduction E. AUKEN A. V. CHRISTIANSEN L. JACOBSEN AND K. I.
