Central Graben - UK/Norway

CNS MegaSurveyPlus

Over 23 500 sq. km of high quality reprocessed seismic in the Central North Sea
Website Map for Survey CNS MSP
The data covers 23 650 sq km of high-quality regional reprocessed data across this key heartland of the UKCS. With better structural imaging, improved signal to noise and pre-stack data available, this is the perfect dataset for regional screening work and rejuvenating this mature area.
The benefit of regional, fully migrated 3D data is the ability to obtain an improved and consistent regional geological perspective. By using this vast dataset to generate a regional interpretation and tie key wells, prospects, plays and migration pathways are significantly easier to define.
The MegaSurveyPlus concept aims to revitalize areas with good data coverage by reprocessing release-age and PGS data from field tapes. Using the most modern processing sequence and processing expertise, the reprocessed data shows a considerable uplift on the legacy data.
