Abstract

Commonly, TEM data is plotted as apparent resistivity versus time. Later on, with improvement in computer technology, inversion programs have got attention of EM geophysical community. Recently, inversion routines are applied to 1-D problems. In this paper we propose a new approach to interpret SOTEM data by carrying out analysis in time, frequency and pseudo-seismic domain. At first, we processed synthetic data for H & K type models using 1-D Occam inversion. Then we transformed time-domain data into quasi-MT domain and conducted 1-D Bostick's algorithm. Finally, EM diffusion field is transformed into wave field reflecting seismic-like response with some reflection and refraction phenomena. Our proposed approach is validated by a case study of a coal field located in Henan province, China.
