4D Processing Workflows

PGS has 4D-compliant imaging solutions to suit all projects.

Each workflow achieves the required quality within the desired timeframe. Time or depth migrated images can be delivered for all vintages.

Ultra-fast track 4D processing

4D processing starts onboard, then 4D binning and subsequent processing steps are performed onshore and usually includes post-stack imaging. Typical delivery timeframe is 4 weeks after last shot.

Fast-track 4D processing

This fast-track is akin to a full integrity processing flow done with maximum efficiency. Typical delivery timeframe is 8 to 12 weeks after last shot.

Full integrity 4D co-processing

Our full-integrity workflow is a state-of-the-art sequence. Vintages are processed in parallel to achieve the best repeatability in a global sense. Delivery timeframe depends on the number and size of the surveys.

Full integrity 4D sequential

For three or more time-lapses, successive vintages can be co-processed two-by-two, minimizing the difference between pairs of successive vintages. This is the most time-consuming approach to full integrity 4D processing.
