Abstract

Rotliegendes sandstones have been found to display a wide range of petrophysical and mechanical properties stress sensitivity behaviour. The extent of stress related changes has been found for permeability, electrical conductivity and Young's modulus to be related by the depositional facies. It has also been noted that the relationship between some rock properties which are thought to exist in situ can not be replicated unless measurements conducted at near in situ stress level are employed. These results lead to the conclusion that the structure reflected by properties measured at low confining pressures is not representative of that which exists in situ.
