Summary
Accurate seismic imaging in complex pre-salt and post-salt environments is essential for reliable
reservoir characterization. This study highlights the advantages of data-domain least-squares migration (LSM) over conventional migration techniques in the Buzios field, the second-largest pre-salt hydrocarbon reservoir in Brazil's Santos Basin. Located approximately 230 km offshore Rio de Janeiro at a water depth of 2 km and extending 5 km below the mudline, the Buzios field is estimated to hold over 3 billion barrels of oil.
