UK Continental Shelf: An Evolution in 3D Seismic Imaging of the Central North Sea

The Central North Sea is a mature petroleum exploration province, with over 50 years of exploration to date. With increased maturity, recent exploration efforts have focused on the deeper targets below the Base Cretaceous Unconformity (BCU), where there is increased risk and often high-pressure, high-temperature (HP-HT) conditions. The key to de-risking these plays is high quality seismic data with good frequency content and high signal-to-noise ratio at depth. With Cornerstone Evolution, CGG has utilised the latest seismic processing technologies to achieve these goals, producing the best-quality regional imaging in the area to date.
