Near-surface modeling and statics challenges
Karen Richard, James Leberknight · 2013
Near-surface modeling is a critical and interpretative step early in the seismic data processing flow. It is interpretative from first break picking to the construction of a geologically feasible model because several approaches may be required to yield the optimal statics solution. This paper will show several of the options available for the critical decisions that must be made during this process. Whether derived from the conventional refractor velocity and delay time method or tomography, these near-surface statics are vital for the accuracy of the data processing flows that follow, preventing incorrect and possibly costly interpretations.
