Abstract

Existing Depth Focusing Analysis (DFA) (Fay and Jeannot, 1986. Willis, 1990, and MacKay and Abma, 1992) has three known limitations: small reflector dip, small offset, and locally-constant velocity. Due to these limitations. DFA is not able to handle complex over-burden problems for velocity model estimation. In the case of strong horizontal velocity variation, DFA may not converge to the true velocity model (Audebert, 1991; MacKay and Abma. 1992).
