Abstract
C-39 WELL-DRIVEN PROCESSING OF A 2D/4C LINE OVER THE ELDFISK FIELD Abstract 1 The Eldfisk 2D/4C test line has been processed using a standard 4C time imaging workflow. Parallel to this a new workflow capitalizing on existing well data has been tested. The new approach included 1D ray tracing of an anisotropic depth model. The model was built from sonic logs calibrated with 4C seabed seismic data. A comparison of the compressional and converted data images produced by the two alternative workflows is presented. Introduction Eldfisk is a field about 10 km southwest of Ekofisk with a water depth of
