Young Professionals Webinar:
Reflections on the Geosciences in Carbon Capture Utilization and Storage through the lens of the Aquistore Project

Date:  Thursday, October 21st , 2021
Location:  Registration open until October 20th.
Time:  12:00 p.m.– 1:00 p.m. (Webinar)
Speaker: Dr. Rick Chalaturnyk


Many future energy technologies in North America and around the world will either directly or indirectly depend on the effective, safe use of the subsurface for either permanent and/or intermittent resource/waste storage. The current, accelerated conversations surrounding energy transition strategies are, for the most part, assuming subsurface pore space is simply available as a ”solution space”. Taking this pore space for granted potentially leads to situations where the risks and challenges surrounding temporary and long-term geological storage opportunities are not appropriately considered. The Geosciences have a significant role to play in meeting the current and future challenges in the energy transition landscape, which lately has drawn significant attention to carbon capture, utilization and storage (CCUS), to ensure safe, effective, economical, sustainable use of the subsurface. This presentation will highlight how the geosciences can play a critical role in CCUS and will use the Aquistore project to highlight many of these roles.

Continuous monitoring of field conditions over 7 years of intermittent cold CO2 injection at the Aquistore storage site has provided substantial learnings related to the subsurface storage reservoir responses under dynamic injection conditions. The Aquistore CO2 Storage Project is an integral component of SaskPower’s Boundary Dam CO2 Capture Project and is located in southeastern Saskatchewan, Canada. The Boundary Dam Project is one of the world’s first commercial post-combustion carbon capture, utilization, and storage projects where CO2 is captured at SaskPower’s Boundary Dam coal-fired power plant and is primarily used for CO2-EOR operations in the Weyburn Field. Operational synergies between the capture facility (supply) and CO2-EOR (demand) also require excess CO2 to be transported via pipeline to the Aquistore site where it is injected into a hyper-saline fluid filled sandstone formation at approximately 3300 m depth. The injection interval consists of the Deadwood and Winnipeg Formations, which lie unconformably on Precambrian basement rocks, and is overlain by the Icebox Member of the Winnipeg Formation and the Prairie Evaporite. The reservoir temperature is 116 °C, and average reservoir pressure is 35 MPa. Preliminary laboratory measurements on core plugs gave average values of porosity and permeability, 6% and 5 mD respectively. This presentation will highlight observations of hydromechanical (pore pressure) and thermomechanical (pore temperature) processes are involved in the CO2 injection. The presentation will also review data collected from DTS/DAS systems and downhole tubing and casing conveyed pressure sensors over this 7-year period and highlight several learnings observed in the data. An update on issues related to salt precipitation that was initially observed during a downhole camera deployment in May 2017 will be discussed in relation to a follow-up downhole camera run in August 2020.

Dr. Rick Chalaturnyk
Rick Chalaturnyk is a Professor of Geotechnical Engineering in the Department of Civil and Environmental Engineering at the University of Alberta and holds an NSERC/Energi Simulation Industrial Research Chair in Reservoir Geomechanics. Prior to joining the University in 1997, Rick helped co-found a reservoir surveillance company called PROMORE Engineering and after joining the University, was engaged as Executive VP of Opsens Solutions, a company providing fiber-optic and non-fiber monitoring solutions to the SAGD and CO2 Storage world. At the University of Alberta, he has established the Reservoir Geomechanics Research Group, working primarily in the area of subsurface processes related to current and future energy processes and to support the research group, has established four unique GeoInnovation Environments, which includes 3D printing of rocks, high temperature/pressure testing capability and a geotechnical beam centrifuge. He was involved in the IEA GHG Weyburn-Midale CO2 Storage and Monitoring Research Project since its inception in 2000 and is currently active as a member of the scientific and engineering research committee for the Aquistore project in Saskatchewan and several other international CCS initiatives. Dr. Chalaturnyk served as Chair of a Canadian Standards Association Technical Committee that developed CSA Z741-12, a standard for the geological storage of CO2.
