The Tempest Project-Addressing challenges in deepwater Gulf of Mexico depth imaging through geologic models and numerical simulation

摘要

The objective of the Tempest project was to evaluate the industry's ability to correctly image deepwater GOM subsalt structures, using both the exact and a developed velocity model. This was achieved by creating a realistic GOM Earth model and using it as a basis for generating synthetic seismic data. Depth-imaging results enabled the comparison ofrndifferent depth-migration algorithms as well as various acquisition setups, highlighting their positive and negative attributes and, importantly, how they complement each other.
