The objective of this project is to quantify the reservoir properties of Triassic sandstones in Southern Netherlands at depths beyond 1500m in order to assess uncertainty and reduce the risks for future deep geothermal operations. Many Westland geothermal projects at depths between 1500 and 2500m are successful. However, the Triassic reservoirs are geologically much older and therefore have a higher chance of complicating histories. The TRIAS Westland core (NLW-GT-01) analyses show that Triassic sandstone diagenesis is hampering water flow by a reduced permeability in layers at 4200m depth. It shows that to successfully predict heat production there is insufficient knowledge of these sediments, their mineralogy, local structural characteristics, spatial heterogeneity and diagenesis. We propose an innovative integrated sedimentary, structural and diagenetic study to assess, quantify and map their suitability for deep geothermal exploitation in the southern Netherlands. This work should substantiate if and where new deep geothermal projects in the Dutch Roer Valley Graben will be economically feasible.

• Applicants must hold a master's degree or the equivalent in geology, or must have submitted his/her master's thesis for assessment prior to the application deadline. It is a condition of employment that the master's degree has been awarded.
• A strong documented background and interest in sedimentology/stratigraphy, and/or with experience from integrated structural/stratigraphic work will be preferred.
• Candidates who also possess a good understanding of sedimentology/stratigraphy, and/or with experience from integrated structural/stratigraphic work will be preferred.
• Experience from wellbore core analysis is an advantage.
• Experience with any of the following is of potential interest to the project: microstructural analysis and various micro-analytical techniques, porosity and permeability analyses, structurally controlled fluid flow and diagenesis, reservoir/aquifer geology.
• Applicants must be able to work independently and in a structured manner, and demonstrate good collaborative skills.
• Applicants must be proficient in both written and oral English.
• Candidates must be prepared to interact with industry sponsors, although no such previous experience is required.

Technische Universiteit Delft

Delft University of Technology (TU Delft) is a multifaceted institution offering education and carrying out research in the technical sciences at an internationally recognised level. Education, research and design are strongly oriented towards applicability. TU Delft develops technologies for future generations, focusing on sustainability, safety and economic vitality. At TU Delft you will work in an environment where technical sciences and society converge. TU Delft comprises eight faculties, unique laboratories, research institutes and schools.

Faculty Civil Engineering and Geosciences

Faculty of Civil Engineering & Geosciences (CEG) is committed to outstanding international research and education in the field of civil engineering, applied earth sciences, traffic and transport, water technology and delta technology. The research covers global social issues and is closely connected to education as well as the work of a wide range of knowledge institutions. CEG is convinced that Open Science helps to realise these goals and supports its scientists in integrating Open Science in their research practice. Faculty of CEG comprises 28 research groups in the following seven departments: Materials Mechanics Management & Design, Engineering Structures, Geoscience and Engineering, Geoscience and Remote Sensing, Transport & Planning, Hydraulic Engineering and Water Management.

The Department of Geoscience and Engineering is part of the Faculty of Civil Engineering and Geosciences and encompasses five sections: Applied Geology, Applied Petrophysics and Geophysics, Geo-Engineering, Resource Engineering, and Petroleum Engineering. Within the Department there is considerable scope and encouragement for interdisciplinary research.

The increasingly intensive use of the Earth subsurface calls for detailed understanding of its geometric and physical properties. The Applied Geology section develops knowledge to quantify subsurface sedimentological and structural heterogeneities and their impact on the mechanic and flow behaviour. Adopting a multidisciplinary approach we combine analysis of outcropping analogs (recent and fossil) with characterization and numerical modelling tools. PhD candidates, post-docs and staff in the Applied Geology section cooperate in a collegial atmosphere in directed towards developing cutting-edge technology for production, storage, and remediation of energy resources. PhD candidates are stimulated to present their research at international conferences, to publish in high-ranked scientific journals, and to form an international professional network. Graduates of the section find employment in industry and in the academic world.
