MAJOR AREAS OF RESEARCH
Emulsion Formation and Stability
Reservoir Wettability Alteration
RECENT RESEARCH ACTIVITIES
Our motivation in this area is to understand the fundamental mechanisms that govern solids partitioning at liquid-liquid and liquid-gas interfaces. We assembled a unique, high pressure interfacial tensiometer that is capable of performing interfacial rheology measurements at pressures up to 10,000 psia. Our work in this area has recently been focused on the impact of brine on solids partitioning at liquid-liquid interfaces.
Emulsion Formation and Stability
Emulsions are ubiquitous in life and industry, having significant applications in energy, agriculture, bio-products, and pharmaceuticals. Our current focus is on understanding the impact of silica nanoparticles on surfactant partitioning in water-in-oil and oil-in-water emulsions. Through the use of high resolution nuclear magnetic resonance, we quantify transient droplet size distributions and elucidate stability mechanisms. The immediate application of our work is improved oil-water separation strategies with significant environmental and economic impacts.
Flow assurance challenges arising from hydrate formation, wax deposition, and asphaltene deposition continue to plague the energy industry. Our work focuses on hydrate formation in emulsions and the impact of nanoparticles and wax on hydrate formation. We combine molecular level understanding (through the use of nuclear magnetic resonance) with macro-scale measurements (bulk rheology) to quantify hydrate behavior.
Our work in separations focuses on three fronts: 1) viscous distillation 2) entrainment characterization and 3) high pressure gas evolution. We constructed an Oldershaw column to quantify the impact of viscosity on mass transfer efficiency. For entrainment characterization, we use phase doppler interferometry to interrogate dense sprays with the aim of developing improved understanding and strategies for dealing with liquid entrainment in gas-liquid systems. For high pressure gas evolution, we developed a unique experimental facility designed to quantify the kinetics of gas evolving from liquid hydrocarbons at high pressures (up to 6,000 psia).
Reservoir Wettability Alteration
We are developing new techniques to improve hydrocarbon recovery by altering reservoir wettability. We combine high pressure (10,000 psia) contact angle measurements with high resolution micro-CT measurements to interrogate factors that affect reservoir wettability.
