Abstract

Multiple Attenuation using radon filtering is commonly used for suppressing multiple energy technique at seismic data. The basic concept is to do separation between primary and multiple in radon domain by using residual moveout value. The method is used for synthetic seismic data called GM1 as marine precipitation zone. The data is found multiple, dominantly as peg-leg multiple. The study is being done in order to know how much radon filtering can influence both for Common Mid Point (CMP) stack and Common Reflection Surface (CRS) stack to attenuate multiple. The imaging of CRS stack is expected will be able to create higher signal to noise ratio than conventional method. Radon filtering is applied to CMP gather and CRS supergather. Radon analysis can^t able to reduce peg- leg multiple overall in CMP gather and CRS supergather. Signal to noise ratio of stacking section can be enhanced by CRS stack method significantly.
