CGG is currently reprocessing its Cornerstone surveys in the Central North Sea, using the latest cutting-edge imaging technology to create a contiguous data volume of over 35,000 km². Data will be available in time for the 32nd UK Licensing Round, and impressive high-resolution new images of the Forties channels have already been achieved.
Processing is being tailored to address local geological complexities, with model-building benefitting from Q-Tomo, Q-FWI, and Q-RTM. Final PSDM data sets will include Least Squares Q-Kirchhoff and Wave Equation migrations.

The East-West Phase 8 BroadSeis data overlies the earlier conventional North-South data over the High Pressure High Temperature (HPHT) area of the Central North Sea. These two datasets were merged to produce a dual-azimuth volume, delivering:
Cornerstone PPP provides volumetric pore pressure predictions to identify overpressure anomalies which could indicate potential pay zones or possible drilling hazards. CGG combines expertise across the geosciences to integrate high-resolution seismic and velocity models with petrophysical and well-log pressure data to deliver a range of pore pressure products to address the challenging HPHT North Sea reservoirs.
CGG offers more than 16,000 km² of integrated PPP data (indicated in blue on map) as part of our Cornerstone data set.
Facies Finder maximizes the value of seismic data early in the E&P cycle to highlight and de-risk potential prospects. It provides easy-to-interpret attribute volumes for lithology and fluid identification using an elastic inversion. The method requires no well calibration, making it suitable for exploration and screening for AVO anomalies.
