Petrophysics and Geomechanics

We run a number of joint industry projects utilising the specialist facilities available in the Wolfson Multiphase Flow Laboratory. Research focuses on the petrophysical properties of low permeability rocks and development of models to predict those properties. We also have expertise in geomechanical modelling and an interest in how geophysical indicators of stress and mechanical property distributions within reservoirs can be integrated with coupled geomechanical- fluid flow models to predict reservoir behaviour.

Current research projects

Wolfson Multiphase Flow Laboratory

The Wolfson laboratory was established in 2006 and has recently been refurbished and up-graded thanks to a £300,000 grant from the Royal Society Wolfson Laboratory refurbishment fund as well as matching funding from the University of Leeds. The laboratory was initially established to investigate the multi-phase flow properties of fault rocks for predicting the flow of petroleum in the subsurface. In the first four years of operation the laboratory became the first to measure the relative permeability, capillary pressure and wettability of fault rocks within petroleum reservoirs. This builds on over 10 years of work that has been conducted in Leeds on the microstructure and petrophysical properties of fault rocks.

More recently the laboratory has undertaken major research projects on the petrophysical properties of tight gas sandstones and on measuring the properties of shales in both top seals and shale gas reservoirs.

The laboratory has state-of-the art facilities including a CT scanner, flow systems for relative permeability and capillary pressure determinations, an ultracentrifuge, pulse-decay permeameter, NMR, as well as equipment for investigating the electrical and ultrasonic properties of rocks. The laboratory has two temperature controlled laboratories that are specifically designed for measuring the multiphase flow properties of low permeability rocks.
