Paper Summary
Imaging technologies such as Kirchhoff Migration and Reverse Time Migration (RTM) provide a level of seismic resolution that suit the industrys expectation of capturing hydrocarbon reservoirs and outlining prospects. Over the last few years, Least-Squares Migration (LSM) has become the new standard in high-end seismic imaging, providing a higher level of granularity necessary for prospect risk mitigation, reservoir characterization and well planning. In this case study, we present the advantages of using an iterative LSM for imaging and interpretation of presalt reservoirs of the Buzios Field in Santos Basin, offshore Brazil.
