Geophysical prospecting with controlled-source electromagnetic data

Abstract

Controlled-source electromagnetics (CSEM) is an active geophysical technique sensitive to the electrical resistivity of the subsoil, with the peculiarity that the source producing the electromagnetic signal is a man-made device. It has been largely applied for offshore environments in hydrocarbon exploration due to the good penetration depth and resolution, although its application onshore is still under investigation because it is less favorable. In order to study this technique, a dataset was acquired at Samalús (Vallès Oriental) the 22nd and 23rd February, 2017; and in this work a 1D model simulation and interpretation of these data is presented.
