3D true-amplitude prestack depth migration

Feng Deng, George A. McMechan

Open publisher page 5 citations

Abstract

Analysis of amplitude variations with offset (AVO) or with angle (AVA) for reservoir description and for hydrocarbon detection requires reliable amplitude information be obtained from prestack migration. A 3-D true amplitude prestack reverse-time depth migration is developed by compensating the geometrical spreading, intrinsic Q losses and transmission losses. Tests on synthetic models illustrate the feasibility. One practical limitation is the high computational cost.
