An Innovative Approach to Optimize Heavy Oil Recovery Using a Novel Synthesized Liquid Catalyst

Chemical-assisted enhanced oil recovery (EOR) has recently received a great deal of attention as a means of improving the efficiency of oil recovery processes. Since heavy oil production is technically challenging due to its high viscosity and high asphaltene content, therefore, new recovery techniques are often tested and applied in lab-scale. This study will contribute to general progress in this area by synthesizing liquid catalyst (LC) in the lab and applying it to enhance the heavy oil recovery.

An integrated study of CO2-based CSI process and CO2 saline aquifers geo-sequestration

CO2 geo-sequestration is an efficient approach to reduce CO2 emission and achieve zero carbon emission with minimum impact on economic growth and people’s wellbeing. This project focus on optimizing carbon utilization in heavy oil reservoirs and CO2 geo-sequestration in the underline saline aquaifer with three key objectives: optimizing CO2 injection in heavy oil reservoir to enhance oil recovery, understanding the behavior of injected CO2 interacting with formation brine and aquifer rock, and modeling the non-isothermal behavior during CO2 injection process.

Integrating Reservoir System Information for Cyclic Solvent Injection Process to Support Post-CHOPS Field Development

Heavy oil (high viscosity oil) is trapped underground. Cold heavy oil production with sand (CHOPS) is an enabling technology to extract heavy oil through wormholes forming around wellbore. There are thousands of CHOPS wells in Saskatchewan and Alberta with low primary oil recovery. Cyclic solvent injection (CSI) enhanced oil recovery process stands out as one of the most promising post-CHOPS methods.

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.
