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.
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.
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.
