Abstract
Summary
The benefits of simultaneous source acquisition are compromised by the challenges of dealing with intense blending noise. In the abstract, we propose a processing workflow in the case of blended data. The incoherent property of blending noise in the common-midpoint gather is utilized for applying a median filter after normal moveout. The key point in the proposed workflow is the obtainment of a precise velocity map which is required by the following NMO. We use synthetic and field data examples to show the performance of the proposed approach and compare the final migrated images.
