CGG Wells

CGG has performed comprehensive and thorough analyses of the available NPD wells and integrated the results with the NVG seismic data. All disciplines within the CGG Geoscience group have worked together to deliver new interpretation, reviews and analyses of the well data. This work includes error corrections of logs, well-to-seismic ties, biostratigraphy, sedimentology, wire log conditioning and electrofacies.

The multi-disciplinary group has discussed all logs and agreed on editing and modifications in an iterative process. All changes from the original NPD wells are documented.

The result of the geoscientific work is CGG Wells that are consistent and correlated with the seismic and other available geoscience data. This iterative integration and correlation between geology and seismic is undertaken to obtain the best possible interpretation. The CGG Wells, seismic and available geoscience data therefore constitute a fully integrated database ready to be used.

Deliverables for the 50 first CGG Wells

The geoscientific database covers an area of 35,000 km². The first 50 CGG Wells are located in the east of the survey area.
