Quest

The Quest CCS Project, operated by Shell Canada in partnership with Chevron Canada and Canadian Natural Resources Limited, is located near Fort Saskatchewan, Alberta. Commissioned in 2015, Quest captures about 1 million tonnes of CO₂ per year from the Scotford Upgrader’s hydrogen production units, where CO₂ is separated during steam methane reforming. The captured CO₂ is compressed and transported through a 65-kilometer pipeline to an injection site north of Edmonton, where it is stored in the Basal Cambrian Sandstone, a deep saline aquifer more than 2 kilometers underground. Quest has safely stored over 7 million tonnes of CO₂ to date, with extensive monitoring and verification using seismic imaging, pressure monitoring, soil gas surveys, and groundwater sampling. The project was the first commercial-scale CCS facility for oil sands operations, and it continues to serve as a global reference for integrated CCS design and regulatory transparency. Performance data and lessons learned from Quest are publicly shared, contributing to the advancement of future large-scale CCS projects in Canada and worldwide.
