Title

AVO preserved velocity analysis using high-order Radon transform

Pages

  293-304

Abstract

 Velocity Analysis is one of the most important stages of seismic processing. The most conventional method for Velocity Analysis is to calculate the semblance coefficients. Traditional semblance has some shortcomings, for instance, low resolution in time and velocity direction, high computational cost, and having trouble in presence of amplitude variation-with-offset (AVO) phenomenon. In order to compensate for the latest shortcoming, AB semblance has been proposed. However, this method has approximately twice the lower resolution than traditional semblance. On the other hand, due to effects of the source wavelet, seismic events have band-limited nature, which leads to a decrease in temporal resolution. Recently, the Deconvolutive Radon Transform has been introduced to overcome the latest problem. In this paper, we have developed the deconvolutive Hyperbolic Radon Transform for AVO preserved Velocity Analysis. We have also used the log-polar domain in order to reduce computational cost. We tested this method on both synthetic and real field data sets to show resolution improvement in the proposed method. ...
