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

Aquistore is demonstrating the scientific and economic feasibility of injecting CO2 into a deep saline geological formation, and is providing the knowhow for other jurisdictions and companies thinking of doing the same.

The PTRC has over 18 years of experience managing CO2 monitoring and storage -- formerly through its management of the IEA GHG Weyburn-Midale CO2 Monitoring and Storage Project and 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 oilfields.  

As the PTRC's second flag ship project, Aqusitore is a direct result of this extensive scientific and research experience. A Science and Engineering Research Committee (SERC) was formed and has been involved in each step of the project.  The SERC has developed a program to address aspects of CO2 injectivity, containment and capacity, and conduct research activities that will be fully integrated with most field operations associated with storage and monitoring.

The storage of CO2 is taking place deep underground into the Williston Basin, a sedimentary basin present in south eastern Saskatchewan, south western Manitoba, North and South Dakota, and Montana.  This sedimentary basin is made up of alternating porous rocks such as limestones and sandstones, and non-porous rocks like shales, anhydrite and salt.  The target injection zone is called the "Deadwood Formation" and it is located almost 3.2 km beneath the earth's surface.  As of the end of August, 2017, Aquistore has stored 107,000 tonnes of CO2.

 

The Aquistore injection and observation wells are locted on reclaimed industrial land 2 km west of the Boundary Dam Power Station near Estevan. For more detailed information about the project, visit the Aquistore website at http://aquistore.ca.
