Imaging through gas-filled sediments using marine shear-wave data

摘要

Marine multicomponent sea-floor data of excellent quality have been acquired over the Tommeliten Alpha field. The most dominating wave modes are interpreted to be coventional compressional PP-waves and con- verted PS-waves. The most important geopysical prob- lem associated with the Tommeliten Alpha field is the presence of a gas chimney obscuring the conventional 3-D seismic image of the reservoir zone.
