"Web7.1 INTRODUCTION Chapter 3 showed that the derivation of datum static corrections was generally based on a fairly simple near-surface geologic model. The lack of detailed near-surface information leads to some inaccuracies in this model and therefore in the datum static corrections. In addition, datum static corrections are not a unique set of values … " - Static correction seismic
