NSERC Industrial Research Chair/AITF Industry Chair in Modelling Fundamentals of Unconventional Resources

The Chair program is focused on understanding of the physics of multiphase flow in porous media in three main areas: conventional heavy oil, bitumen in oil sand, and bitumen in carbonates.

This program will improve field exploration, development, recovery and production methods and strategies, as well as provide information, technology, and fundamental concepts essential for enhancement of the recovery of unconventional resources, integrating research and innovation into industry by providing them with graduates who have experience that can be used to solve practical problems.

Apostolos Kantzas

Dr. Kantzas received a Dipl. Eng. in chemical engineering from the Aristotle University of Thessaloniki, Greece, in 1982. He continued his education with an MASc and PhD in chemical engineering from the University of Waterloo, Canada in 1985 and 1988, respectively.

Dr. Kantzas is a professional engineer with APEGA and a member of the Society of Petroleum Engineers (SPE), the Petroleum Society of CIM, CSChE, AIChE, and SCA. He has authored or co-authored over 350 technical papers and over 500 technical reports.

  • PI (Principal Investigator), Industrial Research Chair in Fundamentals of Unconventional Resources (FUR IRC)

Selected Awards:

  • 2003 – Department Research Award, Chemical and Petroleum Engineering
  • 2001 – Awarded a prestigious Canada Research Chair (CRC) in Energy and Imaging

Research Activities: 

Dr. Kantzas leads a 40+ member research group that operates a series of laboratories that specialize in challenges related to energy and imaging. A full core analysis laboratory is used for the determination of rock/fluid interactions and fluid flow phenomena in porous media that include; capillary pressures (both centrifuge and porous plate); relative permeabilities (steady state, unsteady state, centrifuge); wettability, and recovery efficiency. The laboratory is also used in Coal Bed Methane research (including measurements for gas in place determination), enhanced oil and gas recovery research, as well as heavy oil and oil sands technology. Reservoir simulation packages are used for predictive studies on reservoir performance, including improved conformance and enhanced oil recovery.

The group has pioneered work in process tomography of porous media and other physical or chemical processes is done using a facility that includes x-ray CAT scanners, gamma camera systems and x-ray imaging systems as well as a new micro-tomography system. Computational fluid dynamics programs are used for the modelling of such processes.

Pore Level Modelling

The current focus of Dr. Kantzas’ research program evolves around pore level modelling of multiphase flow in porous media at the pore level. Applications include multiphase flow in heavy oil and bitumen reservoirs, as well as tight oil and gas reservoirs

Low Field Nuclear Magnetic Resonance

The FUR group are developing modalities and algorithms useful for characterizing heavy oil and bitumen formations. New projects investigate the use of low field NMR for monitoring of the VAPEX process and measuring bitumen production wells. Results from these studies will be applied to exploration and development in Canadian fields.
