Core Description Services

Cores are basically interpreted in terms of their depositional environment. As small-scale sedimentary structures can not always be identified in borehole images, cores may serve as an important indicator and calibration for facies analysis.

Recognising flooding surfaces in cores, for example, facilitates the building of sequence stratigraphic models and correlating systems tracts. Trace fossils are important palaeo-environmental indicators and can be attributed to an ichnofacies type, providing crucial information about the depositional milieu.

Core fracture patterns are mapped by using circumferential transparencies from which dips can be computed (core goniometry). The resulting data can be used in detailed analyses of both palaeo- and current-stress frameworks.
