Peyman Pourafshary received his PhD from the University of Texas at Austin in Petroleum Engineering in 2007. He has worked as an Associate Professor in Petroleum Engineering Department in School of Mining and Geosciences in Nazarbayev Univesity since 2018. Prior to this position, Dr Pourafshary was an Assistant Professor in Tehran University in Iran for 6 years (2007-2013) , and Sultan Qaboos University in Oman for 4 years (2013-2017).
Dr Pourafshary has been involved as the project manager and consultant in different research and industrial projects in US, Iran, and Oman in the field of reservoir engineering and production engineering. Most of these projects were related to the evelopment of new, cheap, and effective methods to reduce the recovery cost and improve the oil production. Several research groups were formed, consisting of graduate students and industrial collaborators, under the supervision of Dr Pourafshary to work on topics in different methods of EOR, production engineering modeling and optimization, formation damage control, and stimulation fields.
The goal of his research is to improve the performance of conventional/unconventional EOR methods and to devise new and cheap approaches for better oil recovery. Several experimental and modeling research activities have been completed to study new ideas for different secondary and tertiary recovery methods such as low salinity water flooding, ion management in water flooding, chemical EOR by nanofluids, and gas flooding scenarios such as carbonated water injection. Also, new approaches were investigated to control and remove different possibilities of formation damage in oil reservoirs to improve wells productivity and injectivity. Mechanisms such as fines migration, clays swelling, and asphaltene precipitation are targeted to be controlled during conventional operations such as water flooding, gas injection, and natural depletion in reservoirs. Another direction of his research is in the field of fast reservoir simulation. In addition to conventional grid-based simulation methods, new fast simulation approaches were developed to model primary/secondary/tertiary recovery stages. These methods were applied in joint research projects with industries for field applications such as water flooding modeling and reservoir characterization.
Dr Pourafhary have taught several undergraduate and graduate petroleum engineering courses in different universities worldwide. The following courses are presented by him at different levels.
- Reservoir Engineering

Petroleum Reservoir Geomechanics: which is the application of Rock Mechanics and Geoscience in the upstream E&P activities involving changes in in situ earth stresses, injection/production of hot/cold fluids, fracturing of rocks, reactivation of faults, well bore stability, drilling and earth stresses, pore pressure prediction (PPP), thermal reservoir geomechanics, caprock integrity assessment, design of hydraulic fractures, drilling at great depth and harsh environments, induced seismicity, sanding and sand control, ground subsidence due to withdrawal of fluids, genesis and properties of natural fractures, mechanics of deep solid waste disposal, and geomechanical impacts of sequestration of carbon dioxide in sedimentary basins. The image in the left side is an InSAR (Interferometric synthetic-aperture radar) satellite image of a SAGD (Steam Assisted Gravity Drainage) operation in Alberta, Canada, showing the surface heave above the thermal operation as result of thermal geomechanics effects. The image in the right is a schematic view of thermally induced shearing in sandstone.Heavy Oil Recovery: Viscous oil (i.e., heavy oil, extra heavy oil, and bitumen) can be defined as all oils with in situ viscosities > 100 centi-Poise. Technologies required to exploit heavy oil differ from conventional oil production practices due to low oil mobility under reservoir conditions, chemistry of the heavy oil (i.e., larger organic molecules and higher asphaltene content), and the recovery mechanisms involved. The world endowment of Viscous Oil is estimated at 7-11 Trillion barrels. Canada is the world leader in technology development for Viscous Oil production and it is the only nation in the world that more than 50% of its oil production comes from Viscous Oil resources mainly located at the borderland between the provinces of Alberta and the Saskatchewan. Viscous Oil is currently responsible for production of 7-10 Million barrels of the total daily world oil production. This figure is expected to grow in the decades to come as the world is running out of cheap conventional oil (the decline rate of conventional oil reservoirs is about 6-8% per annum). Dr. Shafiei’s research covers various topics in heavy oil recovery and characterization of heavy oil reservoirs (i.e., reservoir characterization and appropriate production technology selection for the Karazhanbas heavy oilfield in Kazakhstan), resource estimation, reservoir characterization, developing screening criteria, investigation of recovery mechanisms, recovery techniques, reservoir simulation tools development, and technological, economic, and environmental challenges related to the Viscous Oil industry. The images in the upper row from left to right show a very simplified and schematic plan view and profile view of vertical well steamflooding in a naturally fractured heavy oil reservoir, respectively. The image in the left side of the second row shows a simple numerical model developed to simulate reservoir performance due to steamflooding via using a vertical well. The image in right side the lower row is a conceptual model for thermal geomechanics effects during thermal heavy oil recovery from naturally fractured carbonate reservoirs.
EOR/IOR: Much of the oil is left in the oil reservoirs after primary stage of production in a reservoir’s life when the reservoir is depleted and has ran out of its natural energy (i.e., compaction drive, gas cap drive, water drive) to enable flow of the hydrocarbon into the production well at desired rates. Enhanced Oil Recovery, which nowadays is used alternatively along with Improved Oil Recovery (IOR was used to describe only waterflooding and gas injection as secondary oil recovery techniques in the past), constitutes all techniques and technologies developed to encourage flow of hydrocarbons in porous media and improve the hydrocarbon recovery efficiency. Most of the giant oilfields on earth are now in their secondary or tertiary stage of production life, which requires effective and efficient EOR/IOR plans to maintain or enhance the oil production and maximize the recovery factor. Dr. Shafiei’s focus of EOR/IOR research is on investigation of various aspects of both non-thermal and thermal techniques such as waterflooding and steam processes in sandstone reservoirs (clastic), fractured carbonates, and oil sands. Application of nanomaterials in EOR approaches to improve the efficiency of oil recovery.
Petroleum Geoscience: Petroleum geoscience plays a crucial role in shaping our understanding of the many elements (aka the petroleum system) contributing to the formation of sedimentary basins, a habitat for hydrocarbons, and generation of hydrocarbons from organic matter over geologic time. A proper understanding of the petroleum system (i.e., origin, genesis, properties, migration, and entrapment of the hydrocarbons plus evolution of porosity and permeability) can led to a more realistic assessment of a potential hydrocarbon play. Petroleum Geoscience studies can help with optimum development and management of hydrocarbon reservoirs in terms of resource estimation, rock and fluid properties characterization, identifying the geological elements controlling the oilfield (geometry), reservoir quality assessment, building whole earth models (static reservoir models), reservoir description, reservoir characterization, design of optimum drilling programs, optimum field development planning, and appropriate production technology and strategy selection. Dr. Shafiei is interested in various aspects of the petroleum system, petroleum geological studies, carbonate geology, origin of oil, and thermal and burial reconstruction of sedimentary basins (Basin Analysis and Modeling), and petroleum exploration techniques.
Artificial Intelligence in E&P: Owing to the highly complex nature of the geological systems in terms of the processes involved, properties and characteristics of the rock and fluid systems, and complexity of the fluid flow in such systems, there is always a great deal of uncertainty involved in characterisation of the rock and fluid properties and prediction of performance of different mechanisms involved in hydrocarbon production. Obtaining enough and representative samples of reservoir fluids and rocks is also very challenging, costly, and time consuming. So often, at the very early stages of reservoir characterization and development, data is scarce and generation of sufficient high quality data can be expensive and time intensive. Artificial Intelligence approaches can help lower the uncertainties associated with the nature of the materials from earth where a limited time and data is available. Dr. Shafiei conducts research on application of AI techniques for process understanding, developing quick reservoir ranking tools, and AI model optimization using various mathematical methods and novel algorithms. The image shows the architecture of a three layer artificial neural network model developed to predict cumulative steam to oil ratio (CSOR) and recovery factor (RF) in a steamflood project conducted in a naturally fractured heavy oil carbonate reservoir.
Other Research Interests: In addition to the above-mentioned areas, Dr. Shafiei also conducts research on various aspects of reservoir monitoring tools development and application, leaky hydrocarbon wells (i.e., environmental impacts, policy, and enhanced approaches for well cementation and well abandonment practices), petroleum economics, E&P technology management, future of oil, emerging technologies, and energy policy.
