Abstract
When no direct measurements are available, detailed knowledge of the compressional- and/or shear-wave velocity fields is essential for quantitative estimation of gas hydrate and free gas in bottom-simulating reflectors (BSR). Discrepancies between experimental velocity profiles and the velocity for water-filled sediments reveal the presence of gas hydrate (positive anomalies) and free gas (negative anomalies).
