Propagating expected variability in structural geometry through the seismic processing and interpretation workflows considers inherent errors however fails to constrain uncertainty in the interpretation.<div><br></div><div>Misinterpretation may occur when practitioners make a categorical decision adjusting the assumptions applied during interpretation. Applying different a priori knowledge this may lead the interpreter to apply inappropriate base values during stochastic modelling.</div><div><br></div><div>Modelling the seismic reflection response of alternate interpretation cases provides new insight into interpretation uncertainty. Furthermore it provides the initial steps of quantifying interpretation uncertainty.</div><div><br></div><div>Understanding the illumination, resolution and detectability of data constrains the variation of interpretation uncertainty in space. Combining knowledge of this spatial variation with basic logic of interpretation provides a means to greatly improve our potential to conceive and consider alternate models.</div>
