Imaging through gas-filled sediments with marine S-wave data
- and others
This paper shows how multicomponent marine data acquired using three component geophones planted into the seafloor could be used to image through a gas filled overburden. Data from the Tommeliten chalk field contains strong S-wave arrivals which are interpreted as P to S-converted waves, where the conversion takes place at the target reflector. Subsequent processing using the Common Conversion Point (CCP) concept produced a section were the major target reflectors could be identified and mapped inside the gas filled area. The conventional 3D seismic data provides unreliable structural images and the interpretation is dubious in an area with an horizontal extent of approximately 2000 m. Using the S-wave data, the horizontal extent of the uncertain area has been narrowed down to approximately 800m.
