Salt interpretation for depth imaging in the GoM

摘要

Salt imaging has significantly improved throughout its evolution. Producing subsalt images representative of true geology is a major challenge for exploration. Subsalt exploration in the Gulf of Mexico (GoM) improved in the 1990s when modern 3-D prestack depth migration became available. The Mahogany discovery in 1993 proved the subsalt profit potential in the GoM. Since then, advanced seismic acquisition and processing technologies have been applied in the GoM for subsalt exploration, improving images and leading to major subsalt discoveries.
