Abstract

CRS stack procedure is a data-driven imaging method which is independent of an explicit velocity model. The pragmatic search strategy for CRS attributes consists of three one-parameter searches. This implementation determines only one optimum stacking operator for each ZO sample to be simulated. Consequently, conflicting dip situations are not taken into account. In one of the efforts to overcome this problem, the strategy has been extended in order to take into account up to five conflicting dips at each sample. Here, we propose a strategy which considers all possible angles and, thus, accounts for all the conflicting dips that may exist at one sample. This strategy has some advantages that improve the continuity of reflection events as well as diffractions in the presence of conflicting dip situations. It also generally emphasizes diffraction events in the stacked section such that we may call it common-diffraction-surface stack. Here, we processed the Sigsbee 2A synthetic data and a real land data set with the new method. The stacked result of Sigsbee 2A and the results of the poststack depth migration of the real data also proved that the stacked section of the CDS stack is a suitable input for migration.
