Abstract

Summary

Seismic diffraction imaging (DI) is applied to the Barents Sea Wisting field, using the velocity and reflection dip fields obtained from a legacy PSDM. The objective is to image steeply dipping faults. The fault definition obtained from the DI is compared to the legacy PSDM and also to a high resolution P-cable survey. The improved resolution and detectability of the fault systems by DI offer a significant added value for interpretation of the legacy PSDM as well as the P-cable.
