D043 Improving Seabed Logging Sensitivity in Shallow Water through Up-Down Separation F. Roth* (Electromagnetic Geoservices) & F. Maaø (Electromagnetic Geoservices) SUMMARY A shallow water Seabed Logging (SBL) model is presented to demonstrate that airwave removal by separation of up- and downward traveling wavefields is capable of increasing the detection depth of the SBL method by several hundreds of meters. To achieve such improvement a proper choice for the seafloor resistivity in the up-down separation processing is essential. This is illustrated by examples of normalized magnitude vs. offset (MVO) curves obtained for various assumed seafloor resistivities some of which produce processing
