Investigation of Water-in-Oil Emulsion on CSI Solvent Dissolution and Ex-solution Performance for Heavy Oil

This research work will establish a systematic workflow for analyzing transient equilibrium foamy oil phase behavior by coupling the CCEC tests, depletion rate and presence of water-in-oil emulsion which are seldom performed for heavy oil. It will provide a strong connection and comparison with previously studies which was conducted in the absence of water-in-oil emulsion. It will create a strong connection between phase behavior with fluid properties, operating conditions and kinetics.

Scaled Physical Modeling of Geomechanical Implications of Wormholes During CO2-Based CSI in CHOPS Reservoirs Part A: Centrifuge Testing of 3D Printed Specimens

Deliberate massive sand influx used to increase oil recovery from shallow heavy oil resources ultimately results in low oil recovery. This means 85-95% of oil would remain unrecovered during the co-production of oil and sand process, which is referred to as Cold Heavy Oil Production with Sand (CHOPS). In this project, we looked at the possibility to enhance oil recovery using CO2 injection.

Flow Optimization for Wormhole Regions of Post-CHOPS Reservoirs

This project aims to provide Canadian petroleum companies a comprehensive big-data-analytics tool that concludes the essential controlling parameters which enable successful experimental and numerical studies on CO2-based solvent injection processes in post-CHOPS reservoirs. The proposed database includes relevant experimental research work that expand through multiple experimentation scales, as well as relevant numerical research work that cover from pore network simulation, Darcy-scale reservoir simulation, CFD simulation etc.

Evaluation of CO2 Sequestration Opportunities in Lloydminster Post-chops Heavy Oil Reservoirs and Underlying Aquifers

Carbon capture and storage is a feasible, reliable and economic approach to reduce CO2 emission. Llydiminster area on the boarder of the provinces of Saskatchewan and Alberta is an area with significant heavy oil production and a large amount of CO2 resources from thermal operated heavy oil production facilities and oil upgraders. Deploying CCU technology in this area can significant reduce the CO2 emission in the oil industry in this area. This study focus on feasibility of carbon geo-sequestration in those heavy oil reservoirs and underlying aquifers in this area.

Machine Learning-Assisted History Matching for Light and Tight Oil Reservoirs

The use of ionic liquids (ILs) in enhanced oil recovery is considered a new and promising technology as it has never been tested in any pilot plant or reservoir field. ILs are very similar to surfactants as they help reduce the interfacial tension, change the wettability of the reservoir, and some have strong viscous effect, all essential factors in recovering more heavy oil. The technology can also be used for medium and light oil recoveries with other kinds of ionic liquids.

Microfluidics Study of Three-Phase Non-Equilibrium Phase Behavior

CO2 management have been an important research theme to minimize the GHG impact on Canadian environment. Enhanced oil recovery by injecting CO2 underground is a very efficient way to minimize the CO2 environmental effect. Meanwhile, after primary and secondary production, either CHOP or CHOPS well present a high water cut in the produced liquid stream. This high water cut has a significant effect on choosing the proper post-CHO techniques.

Developing surfactant–nanoparticle systems for enhanced oil recovery

There has been a growing interest in the application of nanotechnology for enhanced oil recovery (EOR). Nanoparticles possess unique physical and chemical properties due to their small size. In addition, their surface coating can be easily tailored for a particular EOR application. The proposed research will develop surfactant-coated nanoparticles as an additive. These nanoparticles will increase the recovery of residual oil in unconventional reservoirs found in Saskatchewan. Silica nanoparticles will be coated with zwitterionic surfactants.

Modelling And Experimental Measurement Of Solution Gas / Solvent Dissolution And Exsolution In Heavy Oil

Foamy oil is commonly observed phenomenon during cold primary production of heavy oil reservoirs. Along with the pressure depletion, a type of anomalous flow of oil and gas phases appears when pressure is lower than the thermodynamic saturation pressure. Foamy oil is believed to bring positive effects to heavy oil recovery and well productivity by promoting favored fluid properties and oil swelling. The proposed study focuses on the description of the complex phase behavior of foamy oil systems to examine equilibrium versus non-equilibrium behaviour at different depressurization rates.

In-Situ Stresses at the Aquistore CO2 Storage Site Based on Integrated Analysis of Downhole and Core Testing Data

This project will support efforts to reduce greenhouse gas emissions resulting from coal-fired power generation. In this case, the greenhouse gas of interest is carbon dioxide which is captured at SaskPower’s Boundary Dam Power Station near Estevan, Saskatchewan. This carbon dioxide is transported to the nearby Aquistore site, where it is injected into porous sandstone formations at depths greater than 3000 m.
