Abstract

One of the most important steps in the processing of VSP DATA is the separation of upcoming and DOWN GOING WAVES. It can be performed by applying a velocity filter either in the f-k or t-p domain. In the f-k domain, upcoming and DOWN GOING WAVES will be separated into two groups having negative and positive wave numbers, respectively. A simple way of extracting them is to remove energies with the positive or negative velocities in the f-k plane. Similarly, by transforming VSP DATA from t-x domain to t-p domain, upcoming and down going wave fields become separable and they are mapped to different quadrants of a t-p plane. This allows either upcoming or DOWN GOING WAVES to be reconstructed by the application of inverse Radon transform to the related quadrant of the t-p plane. Results obtained by the T-P METHOD are similar to those obtained by the f-k velocity filtering. However, by implementing an amplitude ratio-resting filter in the forward slant stack, the quality of the reconstructed wave field would be improved. The filter was based on the amplitude of a slant-stacked event. The event with different amplitudes can be identified and suppressed when amplitudes are incoherent. In this regared, the efficiency of the f-k filter and the Radon transform over synthetic and real VSP DATA are considered. For the real data, we compared the results of our written softwares with those of the ProMAX software.
