We have a vacancy for a 3-year PhD fellowship at the Department of Geoscience and Petroleum (IGP). The position is within the area of mechanics of chalk for hydrocarbon production for wellbore stability, chalk influx and solids production, and methods of failure mitigation. The study can be experimental, analytical, or numerical depending on the background, qualifications, and interests of the candidate.

It is expected that the candidate will interact closely with AkerBP in analyzing field data and operational practices with goal to integrate new research and technology in AkerBP field operations. The successful completion of the PhD may lead to future employment opportunities. There will be interaction with the current project “Chalk influx and solids production mitigation in the North Sea fields” for transfer and application of technology developed in both projects. The research is relevant to several fields in energy, civil, and mechanical engineering, and engineering physics that involve coupled problems and failure.

The PhD student will be assigned to the Department of Geoscience and Petroleum (IGP) and will be supervised by Prof. Alexandre Lavrov and co-supervised by Dr. Euripides Papamichos.

The Energy and Natural Resources Security group at Los Alamos National Laboratory (LANL) has two openings for Postdoctoral Research Associates in experimental geomechanics. Successful candidates will join a diverse team of scientists who are working to address critical earth science challenges related to energy and national security. Specific research topics related to this opportunity include: (1) experiments using optical fibers to measure distributed strain and temperature inside high-pressure high-temperature vessels; (2) experiments to understand the thermo-chemo-mechanical properties of cementitious composites; and (3) near wellbore modeling with coupled thermo-poro-elasticity. As a member of our interdisciplinary team that includes experts in rock mechanics, well integrity, geophysics, and geochemistry, the candidate will be at the forefront of developing innovative experimental and modeling methodologies to support finding challenges in energy, the environment, and national security. Our facilities for this work include novel equipment such as our large high-pressure high-temperature (HTHP) quad-pore triaxial system, Fiber Brag gratings optical sensors for distributed strain and temperature sensing, HTHP cement curing vessels and calorimeters, HTHP viscometer and Parr reactors, and triaxial core-flood systems with integrated X-ray capabilities. The successful candidate is expected to publish results in high-impact peer-reviewed journals and present their work at conferences. The position is for a two-year term, with the option to extend a third year based on performance and funding availability.

Description

The Faculty of Science and Engineering of the University of Manchester is looking for a highly motivated student to undertake an exciting PhD project on fractured/veined rocks. The student will work in parallel with our ongoing EPSRC-funded INFORM project, where we aim to understand the impact of fracture heterogeneity on the mechanical behaviour of rocks.

This PhD project will increase confidence in the design, construction, and operation of a geological disposal facility (GDF), by integrating X-ray CT analysis and laboratory experiments to understand the influence of mineralised fractures (veins) on the integrity, deformation, and fluid flow behaviour of veined rocks that are often ignored or less researched so far. The student will characterise a range of crystalline and clay formations with veins at the nm scale and develop a bespoke hydrothermal fluid experiment to understand vein-forming mechanisms under subsurface conditions and evaluate its implications on the mechanical deformation of veined rocks. The outcome of this project will underpin the ongoing GDF programme, to isolate radioactive wastes that are incompatible with surface disposal permanently in the subsurface. Nuclear power is low-carbon energy. It now provides about 10% of the world’s electricity, contributing enormously to global Net Zero emissions. One main disadvantage of nuclear power is that its generation process produces radioactive waste that can remain hazardous for hundreds of thousands of years.

The student will be provided full training on Crystal-CT imaging and analysis and will have access to the UK National X-ray Computed Tomography Facility (University of Manchester – National X-ray Computed Tomography (nxct.ac.uk)) at the University of Manchester. The student will also get access to the world-leading rock deformation lab at Manchester (https://www.ees.manchester.ac.uk/research/facilities/). The student will also have opportunities to engage with our excellent project partners from NWS, GFZ, Jacobs, Northeastern University, and our INFORM research team members.

Eligibility

The successful candidates should have, or expect to achieve, at least a 2.1 honours degree and a master’s degree (or international equivalent) in a relevant science/engineering discipline (civil, mining, geotechnics, earth sciences, etc.). A track record of international publications as the first author can be a plus to this role.

Funding

This PhD position is fully funded by the University of Manchester (home student fee only). We also welcome enquiries from exceptional international students but need to find ways to cover the fee difference. Apart from this, we also welcome CSC-funded students to join the research team.

Application Deadline: Friday, 5 Jan 2024 (expected start date: 1 April or 1 Sept 2024)

If you are interested, please get in touch with Dr Junlong Shang (shangjunlongcsu@gmail.com), with a CV and a supporting statement by the deadline.

Geotechnical Engineering Group at NTNU, Trondheim, Norway invites applications for a Postdoctoral position in Geothermal Energy Pile field.

The postdoctoral fellow will investigate Thermal-Hydraulic-Mechanical (THM) behaviour of field scale geothermal energy piles using physical and numerical modelling. The main purpose of this research is to investigate the thermo-mechanical performance of energy piles installed in Norwegian ground conditions such as quick clay. An experimental (lab and field scale) and numerical study will be carried out to investigate the potential of geothermal energy piles in Norwegian climate.

The postdoctoral fellowship position is for 3 years where the main goal is to qualify to work in senior academic positions in future. The postdoctoral fellow will work with Professor Rao Martand Singh (rao.m.singh@ntnu.no). To apply for the position, please click the link below:
