Abstract

Controlled-source electromagnetic (CSEM) surveying has been in use for more than ten years and has become a well-established tool for hydrocarbon exploration in marine environments. On land, however, CSEM methods are rarely applied in a similar manner, since challenges are greater for a range of technical, logistical, and numerical aspects. Over the last five years, the Geo-Electromagnetics working group at the German Research Centre for Geosciences Potsdam (GFZ) has been developing the CSEM method for land-based applications, including a three-phase current transmitter allowing for arbitrary source polarizations, new robust data processing concepts, and 1D to 3D modelling and inversion software. The CSEM hardware and software has been successfully applied in a series of surveys on different targets. We show examples from case studies, including 3D inversion results from the Ketzin CO2 injection test site in Northern Germany.
