- Fault Damage and Petrophysics in Carbonate Reservoirs
We have a fully-funded PhD studentship available (NB - UK/EU citizens only), based in the School of Geosciences at the University of Aberdeen. Project details below. Informal enquiries to me (d.healy@abdn.ac.uk). Formal applications can be made online (http://www.abdn.ac.uk/postgraduate/apply.php). Application deadline is 31st May 2010.
Supervisors : Dave Healy, Ian Alsop and Joyce Neilson
Stipend : minimum of £13,290 (based on 2009/2010 rates)
Start date : Autumn 2010, but sooner if possible
Carbonate hydrocarbon reservoirs are highly heterogeneous in their internal fabric and structure, mainly due to the variety of depositional and diagenetic processes that affect these rocks. This intrinsic heterogeneity presents major challenges when characterising the physical properties of a reservoir, either from reflection seismic or well log data. An additional factor in many regions is due to the effects of fractures ; variations in fracture patterns around faults provide an extra source of heterogeneity in fractured carbonate reservoirs. This project will quantify the key petrophysical properties of faulted carbonate reservoirs, in particular the porosity and seismic velocities. This is a fully-funded Joint Industry Project with Total and BG Group as project partners, brokered by the Industry Technology Facilitator (ITF).
The student will be trained in : detailed field mapping and sampling of carbonate-hosted faults, with at least two European field sites ; laboratory microstructural and microchemical analysis of carbonates, including optical and electron microscopy, image analysis, and the interpretation of stable isotope and fluid inclusion data ; carbonate reservoir geology and petrophysics. Frequent meetings with the industry partners are integral to this project. Generic skills training will be provided through the University of Aberdeen SkillsForge. Upon completion, the students will be very well placed for a career in industry or academia.
The School of Geosciences at the University of Aberdeen has a sustained, international track record in applied geoscience and engineering research, and provides a centre for knowledge exchange with the local Energy industry. The School is expanding and has world class researchers in Structural Geology and Tectonics, Sedimentology, Petroleum Geology and Geophysics. The University of Aberdeen is investing heavily in the future, with a new state-of-the-art Sports Centre opened in 2009, and a new £57m library due to open in 2011.

- High resolution study of porosity in clay-rich rocks using Cryogenic Scanning Electron Microscopy and Broad Ion Beam Sectioning
We are looking for a candidate with affinity for mineral physics, electron microscopy and image analysis, interested in the study of porous media at nm-scale.
The project is in the field of material sciences applied to fine grained rocks containing pore fluid. The project is funded and supported by a major oil company.
The successful applicant will study the pore space of claystones in drill cores from sedimentary basins, to develop new models of the grain microstructure and the pore space as the basis for mechanical and transport property modeling. At longer term, the results would be of special interest for producing hydrocarbons from unconventional sources.
For this project we will use our new Electron Microscope System. This machine combines cryogenic techniques to vitrify the pore fluids by very fast cooling and excavation of the sample by Ar-beam (BIB, Broad Ion beam) to prepare high quality polished cross-sections for high-resolution imaging (SEM). This allows imaging of pore fluids, pore microstructures and 3D reconstruction of the pore space.
The position is open in the Geological of Institute RWTH Aachen University, recently recognized as a centre of excellence in Germany. The successful applicant will work in an international team (http://www.ged.rwth-aachen.de) interested in physical and chemical processes acting in rocks deforming at different scale. We use field, experimental and numerical modeling approaches, and have access to a powerful range of analytical facilities at the RWTH University as well as co-operations with major petroleum companies. Learning German is encouraged but not required.
Requirements for the applicant :
An M.Sc. or comparable degree in a field related to Material Sciences, Mineral Physics, Geology or Geophysics
Background in mineralogy, electron microscopy and/or experimental physics is an advantage
Strong interest in the development of innovative methods and applications
Proficiency in spoken and written English
Motivated, enthusiastic, and participative work outlook to achieve team goals
