Recognition and correlation of stratigraphic unconformities (disconformities) in the subsurface is impeded by shortage of exploration tools. This is especially a problem in thick shallow-water carbonate packages. Most pedogenic claystones do not stand out on gamma logs. Disconformities usually separate concordant packages with insufficent impedance change across the surface and are doomed to be overlooked unless they are traced by seismic-scale incized valleys or pinned in core. However, stratigraphic unconformities are critical surfaces in outcrop-based sequence stratigraphy, international reference and stratotype sections. This presentation is designed to increase awareness of stratigraphic unconformities in the subsurface and incite more systematic recognition of these features during oil and gas exploration.
