Summary:
F019 SEISMIC DETECTION AND QUANTIFICATION OF GAS HYDRATES IN GOM: AN INTEGRATED FIVE-STEP WORKFLOW Introduction 1 A five-step integrated workflow is developed to delineate shallow gas hydrate using seismic information. We applied the workflow and estimated gas hydrate saturations in two study areas in the northern deep-water Gulf of Mexico. Methodology In this abstract we discuss a five-step integrated workflow (Fig. 1) that enables us to identify and quantify gas hydrates in the deepwater Golf of Mexico (GOM). It includes: 1). reprocessing conventional 3-D seismic data at high resolution using an amplitude-preserving flow with prestack time migration 2) a detailed
