Depth Imaging in the Heide-Buesum Transition Zone Area

The recent Heide -Busum TZ 3D survey from RWE-DEA AG and Wintershall AG presented unusual challenges for depth imaging . Seismic data had to be acquired offshore; in the transition zone and on land . The three datasets were combined with proper source designature and phase matching. The acquisition also made use of the patch technique, resulting in ve ry irregular fold and offset distribution . A new type of normalization, by fold density as a function of offset, is presented that corrects some of these problems .
