We are developing realistic and workable approaches for amplitude-preserving Kirchhoff migration and Amplitude vs. Angle (AVA) analysis to delineate reservoir physical properties. These will lead to improved images and increase the amount and reliability of information that can be obtained from the images. Our effort will focus on (1) obtaining more information from images by implementing ?Amplitude- Preserving Migration? through the use of more realistic imaging conditions and proper accounting for transmission loss, wave conversions, anisotropy, (2) the use of AVA to evaluate formation properties and to carry out velocity analysis and (3) the use of limited-aperture Kirchhoff migration to obtain better trace weights for use in amplitude- preserving migration, and (4) investigation of the effects of various implementations of Kirchhoff migration on the resolution of the seismic image; e.g. how small an object can be resolved and how is this influenced by the migration approach.
