Abstract

Electromagnetic attributes have been extensively used for interpreting marine Controlled Source EM data (CSEM). One of the basic attributes is the so called NAR, Normalized Anomalous Amplitude Response. A few years ago a new CSEM attribute has been introduced for fast and accurate identification of the boundaries of resistive layers. It is based on the asymmetry between the in towing and the out towing responses. Combining NAR and CSEM asymmetry represents a relatively simple way to use jointly the benefits of both attributes. The efficiency of this methodology is improved if seismic and gravity data are included in the work flow. This integrated approach based on seismic data, combined with electromagnetic and gravity attributes has been applied in a complex exploration area in the Barents Sea.
