Ali Akbar Eftekhari


Profile

I am a Chemical and Petroleum Engineering graduate with several years of experience in the modeling and simulation of upstream and downstream oil and gas processes. Besides working with commercial simulators, I have developed prototype computer tools for the modeling and simulation of multicomponent phase equilibrium and multiphase flow in porous media. During my PhD, I used the concept of exergy to devise and develop a procedure for the life-cycle-assessment of zero-emission fossil fuel recovery. As a post-doc researcher, I worked on the application of nanotechnology in the enhanced oil recovery. I have designed and conducted experiments in different scales, including production and stabilization of colloidal suspensions to high-pressure/high-temperature core-flooding experiments for EOR. My scientific passion is the exergy analysis of the energy conversion processes. My other interest is the investigation of various physical and chemical interactions (fluid-fluid, rock-fluid) in the flow of multiphase fluids in porous media. I am also interested in numerical methods and computer programming, fluid phase equilibria, and process simulation and optimization.

The code is also available as a Julia package.
