(Chemical) Industrial Partnership Programme 'Rock-on-a-Chip: Salt-controlled wettability alteration in oil-water-solid systems for applications in enhanced oil recovery'.
The recovery of crude oil from geological reservoirs is a complex multiscale process that involves the displacement of oil from microscopic pores in a porous rock matrix by water that is injected into the ground in large quantities. To a large extent, the efficiency of this process is controlled by the relative wettability and adhesion of oil and water on the rock surface. Within this program, we will elucidate the microscopic mechanisms that govern the interaction between oil, water, dissolved salt and organic and model rock surfaces in a comprehensive programme using a combination of Atomic Force Microscopy (AFM), X-ray diffraction and absorption techniques, optical spectroscopy techniques (Raman, Sum Frequency Generation (SFG)) and macroscopic wettability characterization in combination with combinatorial microfluidic approaches.

Job description
The candidate will study the adsorption of organic molecules from oil and water mixtures to model heterogeneous surfaces mimicking real rock surfaces using confocal Raman microscopy in combination with a microfluidic device. The ultimate goal of this project is to emulate the oil recovery process in an artificial Rock-on-a-Chip device.

This position is based at the University of Twente, in the groups of Dr. Cees Otto and Prof. Frieder Mugele.
To read more about the groups: PCF Group

The task will be to develop a setup consisting of a combination of a confocal Raman microscope, an Atomic Force Microscope and a suitable microfluidic device that enables investigation of the (co-) adsorption of organic molecules such as fatty acids, amines, and small aromatic molecules to model mineral surfaces. The goal is to understand the binding mechanism, preferred binding sites, the adhesion strength of the organic molecules and their role for the efficiency of oil recovery emulated in a microfluidic environment. The project is part of a larger consortium of academic as well as industrial partners. It will be executed at the Physics of Complex Fluids group (Prof. Frieder Mugele) in close collaboration with the MCBP group (Dr. Cees Otto).
Candidates are expected to have a degree in (Applied) Physics or a related field. A background in imaging technology (AFM, Raman), optical spectroscopy and microfluidics is considered as an advantage. The position is available immediately. For additional information, please consult Prof. F. Mugele or Dr. C. Otto.
