Well log interpretation and correlation
Vertical well log trends and their lateral changes within a seismic and biostratigraphic framework represent the most important data for basin-wide correlation. Well logs and GR spectroscopy from the outcrop provide two directly comparable data sets for outcrop-resrevoir studies.

Reservoir-outcrop analogue analysis
Lateral and vertical heterogeneities in facies, petrophysical properties and diagenetic overprint are critical parameters of targeted reservoirs. High-frequency, meter-scale vertical stacking patterns and their lateral variabilities within and across specific depositional environments exert a highly important control on fluid-flow behaviour in the subsurface.

High-resolution data sets of the reservoir architecture and the lateral/vertical distribution of key reservoir features allow improved reservoir models and therefore reduce exploration risk. In addition, such data sets are essential for forward numerical models of sedimentary systems and fluid-flow behaviour during subsequent basin development.

However, industry subsurface data sets bear inherent limitations in both vertical and lateral resolution imposed by the interpolation between wells and within 2D and 3D seismic data sets. These limitations can be redurced or overcome by outcrop-reservoir analogue studies.
