Staff and Students

The work of the Petrophysics laboratory is supported by 4 members of full time academic staff. We currently host 3 PhD students.

Alumni from the lab can be found in academia, industry, and government posts worldwide.

Petrophysics Laboratory

The laboratory offers a range of different techniques including some which are world leading or unique. Our association with the capabilities of the Wolfson Multiphase Flow Laboratory together with nano particle and very high-resolution computed tomography facilities in the School of Chemical and Petroleum Engineering extends laboratory capabilities even further.

Research staff have an extremely good reputation not only in experimental determinations but also in numerical modelling and the development of theory.

Current Projects

- Frequency-dependent electrokinetics, developing theoretical models, carrying out numerical modelling and ground truth in the results with high-quality experimental measurements for the purpose of the development of the electro-seismic technique. This technique is the promise for improving upon the resolution of conventional seismics at the same time as providing rock characteristics remotely.;
- Improvement of oil recovery from hydrocarbon reservoirs using nano particle-based water flooding. The addition of nanoparticles to water floods has potential not only to provide a greater production of oil by their physical presence, but can also act as a vector to deliver functional chemicals to optimise the production of the reservoir;
- The microstructural and flow properties of gas shales. A new project is beginning to examine the interplay between porosity, connectivity and fluid flow across a range of scales to nano scales using very high-resolution computed tomography imaging and advanced volumetric analysis;
- Carbonate petrophysics. In recent years the petrophysics laboratory has, together with the Wolfson Multiphase Flow Laboratory, concentrated on understanding how the petrophysics will characteristics of carbonate reservoirs have been affected by various manifestations of diagenesis, concentrating on the reservoirs in northern Iraq;
- Advanced fractal reservoir modelling. This research strand has seen the development of the idea of reservoir modelling based on multiscale fractals to the stage where almost a complete workflow for making reservoir models which take account of data variability, legislative, such at all scales is possible;
