geometry check is address in this study.Field data is checked for geometry errors before sending it to the processing center. It is necessary to verify/check the geometry to identify the errors in geometry and to rectify them. Generally adopted method is to apply LMO and check for the departures from the LMO. These departures signify the error in the location of, the receivers or shot point. We explore some geological situations where a single set of LMO velocity cannot address the changes in sub weathering. Varying LMO takes care of the variations related to geology. Example of some of the problems and the effect of suggested approach are presented.
