Next-Generation Heavy Oil Recovery Methods
Jalal Abedi, University of Calgary
In-situ heavy oil recovery from oil-sand formations has become economically successful in the past twodecades. Inventions and developments of recovery processes utilizing steam injection such as cyclic steam stimulation and steam assisted gravity drainage have contributed to this success. However, the major weak points of the current steam-based processes are their high-energy consumption, large emissions of greenhouse gases and large consumption of fresh water. It has been found that the compounded effects of solvents and heat on the viscosity of heavy oil can provide heavy crude production rates that could be equivalent to or higher than those from the injection of steam alone. In addition, solvent-assisted processes can also contribute to in situ upgrading, due to formation of two liquid phases, in order to produce higher grades of oil than the original heavy oil. Thus, it is essential to determine the conditions that could potentially lead to situ upgrading. Numerous schemes to utilize solvent and heat have been invented and patented. Each solvent based process showed promising results in laboratory-scale tests. However, there is a distinct lack of basic phase behavior data and mechanistic knowledge relevant to the solvent/heat-assisted -recovery processes. Even the most fundamental experimental data such as solubility of commonly used solvents to bitumen are not available. Quantitative effects of solvent on bitumen viscosity, phase behaviors and transport mechanisms are also not well understood. The objectives of this talk are to describe the solvent assisted processes, to characterize the phase behavior of heavy oil/solvent systems, and to provide quantitative mechanistic insights relevant to the solvent-assisted heavy oil recovery processes. This knowledge is a prerequisite to the optimization of the solvent composition for the solvent injection processes and successful oil recovery.
Bio – Dr. Jalal Abedi:
Dr. Jalal Abedi is an Associate Professor of Chemical and Petroleum Engineering at the University of Calgary. Dr. Abedi has also served as a petroleum consultant in the North America and the Middle East. His current research focus includes experimental measurements of heavy oil/solvent phase equilibrium and EOS modeling. He leads a world- class phase equilibrium research facility and a 20-people research group that is involved in research related to solvent solubility in heavy oil and phase behavior and modeling and simulation of transport processes. He is the principle investigator of SHARP (solvent\heat assisted recovery processes) Research Consortium at the University of Calgary. He has authored or co-authored more than 80 papers.
