Updated processing methods, technologies enhance vintage frontier basin data

摘要

Applying modern processing techniques to data acquired decades ago can produce stark improvements in imaging. However, these improvements require particular care in understanding the seismic source signal. Once this is correctly managed, a modern processing sequence which focuses on noise and multiple removal is particularly successful in enhancing the data, providing a consistent and coherent dataset. These techniques often remain the only method of obtaining enhanced data in areas now subject to strict environmental laws. In the Bay of Biscay, this has revealed new insights into the structures, plays and exciting hydrocarbon prospectivity of this basin. The reprocessed data is a tool for planning new acquisition and identifying new areas for exploration.
