Abstract
S-wave velocity and density information is crucial forhydrocarbon detection, because they help in the discriminationof pore filling fluids. Unfortunately, thesetwo parameters cannot be accurately resolved from conventional P-wave marine data. Recent developments inocean-bottom seismic (OBS) technology make it possibleto acquire high quality S-wave data in marine environments.The use of S-waves for amplitude variationwith offset (AVO) analysis can give better estimates ofS-wave ...Keywords
