Abstract
We propose a curvelet domain strategy to subtract ground-roll from seismic records. We built curvelet domain mask functions from higher scales which are groud-roll-free and project them to the lower scales that are contaminated with ground-roll energy. The mask function helps to preserve the reflected energy and eliminate the ground-roll energy. A synthetic seismic data example is provided to analyze the performance of the proposed method.
