A new generation of deep directional electromagnetic imaging tools is being adopted by the industry to enhance the efficiency of well placement, reduce drilling risk and increase production potential. Schlumberger's GeoSphere reservoir service has been reported to reveal fluid-contact details and successfully map sand bodies more than 30 m from the wellbore. In this paper we employ 3D forward simulations for modeling-based interpretation of deep directional electromagnetic responses and present the results of independent feasibility studies. Optimal configurations for several induction frequencies are determined for various application conditions. This modeling algorithm will serve as a basis for a new inversion-based interpretation workflow.
