PSDM from topography: Using refractions to model subsurface and reflections to image

Published in GEOHORIZONS - 2017


Abstract


One of the main challenges in foothills exploration is deriving a subsurface image which is geologically consistent. The common issues often encountered during imaging are related to fluctuating terrain, near surface heterogeneities, ambiguity in subsurface velocity modeling and an imaging solution addressing the spatial velocity variations. The present study is an illustration of depth imaging in the thrust fold belts, wherein the refraction data is used to obtain good near surface velocity model.
