P234 Methane Hydrates in CSEM Surveys – Analysis of Deepwater Data and Consequences for Processing J.J. Zach* (EMGS AS) & K. Brauti (EMGS AS) SUMMARY Near-offsets data from a recently acquired deepwater Seabed Logging (SBL) survey are analyzed for shallow resistive structures. A model consistent with known methane hydrate properties is found to explain the data. For the survey at hand the lateral near-seabed resolution of the present – day SBL technique was determined to ~100m for frequencies of up to 10Hz. The importance of accurate hydrate maps for SBL processing is illustrated using a synthetic reservoir below the hydrates
