Claim One:
1. A method of seismic processing and imaging to avoid image distortion, said method comprising the steps of: i) obtaining a base case seismic data from a subterranean formation, said base case seismic data including a base case image of said subterranean formation; ii) determining a black hole region in said subterranean formation, wherein said black hole region has at least one physical characteristic not readily available and insufficient information for accurate seismic modeling; iii) defining a black hole boundary condition around said black hole region to reduce or eliminate image distortion wherein image distortion is caused by seismic energy waves interacting with said boundary; iv) performing seismic forward modeling with said black hole boundary condition applied thereto; v) generating a reservoir image from said modeling; vi) comparing said reservoir image with said base case image to determine an impact of the black hole region on said reservoir image; and vii) obtaining a revised reservoir image of the subterranean formation by correcting for said impact.
