The road to better imaging

摘要

Advances in deepwater data acquisition improve subsalt imaging. Today, some of the highest-profile targets in the Gulf of Mexico are in deepwater basins beneath complex salt masses. As such, exploration and production risks are huge. Seismic data should play a key role in mitigating those risks, but unfortunately the quality of the data is often very poor - even in state-of-the-art surveys. Much attention over the last few years has concentrated on data processing, with special emphasis on multiple suppression and, of course, depth imaging. Only within the last couple of years has attention been extended to improving the data acquisition product.
