Abstract

With Pre-stack Time and Depth Migration Technology gaining more and more popularity in the industry, it has been widely felt to readjust the allowance given for migration aperture while designing the field survey. Conventionally migration aperture calculations are made to satisfy the needs of post-stack migration algorithms, and also very often no allowance is given for DMO aperture while adjusting the survey area for mapping a target image. Such type of designs measurably fail in faithful imaging through pre stack migration technology, especially in the fringe zones of target image. In the present study a simple analytical analysis has been made to estimate migration aperture satisfying the needs of pre-stack migration technology. Some real data examples have also been shown.
