This website summarizes the results from the FAULTPROP (Petrophysical properties of fault rocks) project, which was a joint industry project (JIP) undertaken by the University of Leeds, and sponsored by BHP, ConocoPhilips, Shell, Statoil and Wintershall.

The key aim of the FAULTPROP project is to develop a database of high quality measurements of the single and multiphase (relative permeability and capillary pressure) properties of fault rocks to enhance the ability of industry to predict fault-related fluid flow in petroleum systems. Key work elements include:

• Measuring the absolute permeability using gas and formation compatible brine under reservoir stress conditions to assess the accuracy of data currently used in industry.
• Measuring the Hg-injection threshold pressures of fault rocks at reservoir stress conditions.
• Developing methods to correct legacy fault rock property data so that current databases can continue to be used with some confidence.
• Generating high quality experimental data on the relative permeability of fault rocks.
• Assess the impact of wettability alteration on the capillary pressure and relative permeability of fault rocks.
• Assess methods to model the relative permeability and capillary pressure of fault rocks using easy to derive measurements such as micro-CT scanning and Hg-injection analysis.
