Big data – Mega Surveys Pushing the
Boundaries
Content
• Why do we use Geocap?
• From Seeds to Grids
• Data Example: Barents Sea MegaProject
• Data Example: North Sea MegaSurvey
• Integration into ArcGIS
2
Why do we use Geocap
• Gridding process considers multiple polygons
• Handles large data volumes
• Qc in 3D view
• “Grid to Grid” operations
• Merge of grids/horizons
• Illustration purposes
• Time efficient

North Sea MegaSurvey
Post stack merge of public released 3D data and
PGS proprietary data sets
138 000 km² 3D seismic data (Coverage in
Norway, UK, Denmark, Germany and in the
Netherlands)
“Live Product” - the MegaSurvey gets annually
updated with new released surveys and is thus a
growing and expanding data volume
