Aquistore is an on-going CO2 measurement, monitoring and verification project to demonstrate that storing carbon dioxide 3.4 km deep underground in a brine and sandstone water formation is a safe, workable solution to reduce greenhouse gases.


Aquistore is injecting and storing CO2 from SaskPower's Boundary Dam Carbon Capture Facility near Estevan, Saskatchewan.  It  is demonstrating the scientific and economic feasibility of deep saline geological formation storage, and is providing the knowhow for other jurisdictions and companies thinking of doing the same.

The PTRC has over 19 years of experience managing CO2 monitoring and storage - formerly through the IEAGHG Weyburn-Midale CO2 Monitoring and Storage Project (2000-2013) and through an extension of that research in a two-year program called SaskCO2USER, which expanded upon the datasets created at Weyburn to further examine such things as wellbore integrity during CO2 storage, and minimum datasets for assuring safe storage in depleted oilfields.


Aquistore:  Leading the World in Deep Saline CO2 Geological Storage

The largest Active Field Lab in the World for CO2 Measurement and Monitoring

PTRC’s Aquistore Project is the most comprehensive full-scale geological field laboratory for CO2 storage in the world.

With leading-edge technology, the Aquistore Project is demonstrating the safe, reliable and economic advantages of injecting captured CO2 into a 3400m deep saltwater-infused sandstone.

By optimizing CO2 storage, the Aquistore Project has the ingenuity to significantly advance clean technology and reduce greenhouse gas (GHG) emissions.

It’s a big deal.  In Canada and abroad. 

Global Leader in CCUS Intelligence

Aquistore is globally sought for its knowledge, innovation, and its accumulation of unique and extensive data. 

Industry and government partners in Japan, Korea, Australia, the United States, South Africa and the United Kingdom have each been participating in the project to develop their homegrown CO2 storage projects.  Many of these partners and potential partners have visited the Aquistore and Boundary Dam CCS site in person.

While a Canadian project, Aquistore has significant international impact. The Project provides opportunities in capacity building through innovative research, training and education to global partners.

“The continued success of this Project will have incredible implications for reducing CO2 emissions throughout the world.”

- John Gale, Former General Manager,
IEAGHG R&D program, London, England

In Canada, Aquistore is developing highly qualified personnel in CO2 storage, with knowledge exported around the world.

Supporting Canada’s Initiatives on Clean Energy & Climate Change

With Canada’s international commitment to a low-carbon economy, decarbonizing non-renewables by storing CO2 is becoming an important component of GHG reduction.

Aquistore is helping to achieve Canada’s Mission Innovation goals with the trilateral agreement between Canada, USA and Mexico via the North American Climate, Clean Energy, and Environment Partnership.

While renewable energy is the future, there are immediate benefits of CO2 storage for industries with limited options to reduce carbon emissions.


Aquistore has stored +535,000 tonnes of CO2, comparable to planting 3.8 million seedlings over ten years.


CO2 Storage Solutions - Across Industrial Heartland

Through the Aquistore Project, COstorage is being proven as essential to help industries that have few other options manage compliance-quality offsets of their GHG emissions.

CO2 storage is a viable option for steel manufacturing used to build wind turbines, the petroleum products utilized in solar panels, the plants producing cement for hydroelectric dams and nuclear power plants that in turn fuel electric vehicles, and from fertilizer plants that support the growth of food.

In addition to the energy sector, other CO2 industrial point sources such as cement and steel production, chemical manufacturing, and fertilizer production are also being called upon to be climate smart.

Advances in Technology

The Aquistore Project boasts an impressive Monitoring Measurement and Verification (MMV) Program.  Click on the graph below to see the full list of monitoring technologies being tested at the site.

With over 50+ publications in International journals, Aquistore is offering independent analysis and research, and the monitoring program is continuously peer-reviewed.

Aquistore is a commercial-scale project tied to real injection considerations - taking industrial CO2 at variable and intermittent rates from SaskPower’s Carbon Capture Facility at Boundary Dam near Estevan, Saskatchewan.

Aquistore’s knowledge provides fundamental understanding of the reality of CO2 injection for commercial-scale operations, regardless of the CO2 point source.

“The work at Aquistore is relevant to many industries and policy makers because we are accelerating our understanding and verifying the safety of CO2 storage.”

- Dr. Don White of the Geological Survey of Canada and Chair of Aquistore’s Scientific and Engineering Research Committee (SERC).

Aquistore is providing an opportunity to test emerging technology such as the electromagenetic sensor, right.


For the first time, distributed acoustic sensing (DAS) fibre is being used to image CO2 at such extreme depths, revolutionizing seismic technology, how geological data is obtained, and significantly reducing costs. 

Opportunities for Data Access

PTRC has compiled comprehensive datasets to advance CCUS knowledge and provides opportunities for capacity building through innovative research, training and education.

Through its CCUS Data Network (which includes Aquistore and IEAGHG Weburn-Midale CO2 Monitoring and Storage Project), PTRC offers investing partners access to its datasets. These range from the initial design to operation of a commercial CO2 storage site to comprehensive datasets for all aspects of MMV techniques and technologies.

Datasets range from raw sets of 3D/3C seismic surveys, time-lapsed pulsed neutron and sonic well logs, injection volumes, reservoir pressures and temperatures from multiple downhole gauges, reservoir fluid samples, caprock and reservoir cores, and geological and reservoir simulation models.

The investing partners receive access to data through utilization of PTRC’s established Scientific and Engineering Research Committee, comprised of global experts with hands-on experience in areas such as: geomechanics, geophysics, and geologic and hydrogeologic cells.


Science tells us that the only true way to understand something is to take research to demonstration and validate it.  Aquistore does that.

Through the demonstration of conformance of CO2 underground, analyzing how it reacts, assessing its predictability, and verifying it, scientists and engineers are adapting modelling to increase accuracy of predictions and understanding.

Striving to continually advance innovation in clean technology with science-based facts, Aquistore is uniquely positioned to assist governments and regulators to reduce liabilities and meet targets for safer, cleaner, sustainable industries.
