PE Distinguished Seminar Series: Flow of Complex Fluids in Porous Media: Implications for Enhanced Oil Recovery
April 19, 2019 @ 10:00 am - 11:00 am
Dr. Soheil Saraji of the University of Wyoming
Abstract: A common cause of failure for enhanced oil recovery (EOR) techniques at the field scale is poor
volumetric sweep of oil caused by viscous fingering and early breakthrough of injecting EOR
agent. Complex fluids are ideal agents for mobility and conformance control in EOR operations.
The properties of these fluids are highly sensitive to strong intermolecular interactions with
dissolved or dispersed constituents. These interactions cause the conventional liquids and
solids to behave in a fluid-like as well as solid-like manner. The design and improvement
of such high-performance functional fluids for optimal mobility and conformance control
relies on the preparation and organization of distinct chemical structures with key features
engineered on nanometer to micrometer scales. Our goal in the present work is to discover
the links between the nano-, micro-, and macro-scales, and to demonstrate the use of this
knowledge in economically-viable technologies for oil and gas production. We have performed
a comprehensive experimental study on rheological behavior of two complex fluids used for
mobility control during gas injection (i.e., liquid foams) and chemical flooding (i.e., viscoelastic
surfactants). This presentation will focus on these fluids and their non-linear flow behavior
through porous media.
Bio: Dr. Soheil Saraji is an assistant professor of Petroleum Engineering at the University of Wyoming.
He received his PhD in Petroleum Engineering from UW in 2013. He has worked on the characterization
of unconventional rocks and oil recovery from tight reservoirs for three years during
his Postdoctoral research. Dr. Saraji’s background and interest is in interfacial interactions and
nonlinear flow in porous media and their implications
