The impact of reciprocity on prestack source plane wave migration

Abstract

Plane wave migration can produce high quality images that are comparable to those of shot migration with much less computation cost. However, current acquisition geometries do not honor the optimal applications of this technology. In this paper, we discuss the limitation of the acquisition pattern and show that optimal application of the plane wave migration algorithm requires split spread common receiver gathers. Using the synthetic 2D Sigsbee data, we demonstrate the application of the reciprocity principle to generate split spread common receiver gathers and shows its impact on plane wave migration.
