Enhance Predictive Capabilities of Flow Models
of the Shallow Subsurface
Department/faculty: Civil Engineering and Geosciences
Level: Master degree
Working hours: Maximum of 38 hours per week (1 FTE)
Contract: Four years
Salary: Maximum of €2612 per month gross
Job description
Geological reservoir models used in hydrocarbon and groundwater exploitation are typically based on stochastic-geometric interpolation methods. Such methods generate solutions that are locally optimal, but are not constrained by the large-scale geological setting of the reservoir. The aims of this project are (1) to develop a post-processor for an existing low-resolution, basin-scale process-based model of fluvio-deltaic drainage networks and stratigraphy, which is conditioned to large-scale basin geometry and geological boundary conditions. The post-processor should generate explicit, object-based, stochastic realizations of the small-scale reservoir architecture (low and high sinuosity channel belts) to permit analysis of sand-body connectivity, and its controls on fluid flow and mixing of sediments with different provenance; (2) to better characterize subsurface heterogeneity and reduce the solution space associated with well data relative to current (geometric) models; (3) to test the method by performing flow simulations on synthetic and real-world reservoirs, in order to study the dispersal of contaminants in the shallow subsurface and propose strategies for groundwater exploitation.
Requirements
Candidates should have an MSc degree in Earth Sciences (Geology, Geophysics, Physical Geography) or Engineering (Engineering Geology, Hydraulic Engineering, Petroleum Engineering). Candidates with demonstrable expertise in geological or flow modelling and a keen interest in optimization problems are specifically encouraged to apply.
Conditions of employment
The successful candidate will be employed by Delft University of Technology for a fixed period of four years within which he/she is expected to write a doctoral thesis. TU Delft offers an attractive benefits package, including a flexible work week, free high-speed Internet access from home, and the option of assembling a customized compensation and benefits package (the 'IKA'). Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities.
Delft University of Technology strives to increase the number of women in higher academic positions; women are therefore especially encouraged to apply.
