Abstract
Summary
Multiple reflections are always recorded in seismic data. Interpretation and analysis of the data can be affected by multiples interfering primaries. Different multiple removal techniques exist, however, irregular geometries data and noisy data remain a challenge. We present a workflow using geometry-preserving Common Reflection Surface processing, true azimuth 3D surface-related multiple elimination and true azimuth 3D interbed-related multiple elimination. The workflow is applied to two different challenging datasets. Our results demonstrate how data-driven demultiple can be applied to noisy and/or irregularly acquired seismic data even in the presence of steep dips.
