1. n. []

A situation in interpretation of seismic data in which predicted and actual values differ, or when an interpreted reflection does not close, or tie, when interpreting intersecting lines; or when interpreted seismic data do not match results of drilling a well. Mis-ties commonly occur when data of different phases, rather than uniformly zero-phase data, are interpreted together, or data that have different datum corrections are tied. Mis-ties are described as static if they involve a bulk shift of data (as in the case of tying seismic sections with different datum corrections) or dynamic if the magnitude of the mis-tie varies with time (as in the case of data that have been migrated differently).
