Operators Cenovus and Apache Energy began injecting captured CO2 at their Weyburn and Midale oilfields, respectively, in Saskatchewan, Canada, in 2000 as part of enhanced oil recovery operations. The Weyburn-Midale CO2 Monitoring Project, the world's first CO2 measuring, monitoring and verification initiative, was conducted alongside EOR operations between 2000 and 2011 (see below).

The Weyburn oilfield, first discovered in 1954, covers an area of 52,000 acres and has 963 active wells (534 vertical wells, 138 horizontal wells) and 171 injection systems. There are also 146 abandoned wells.

The CO2 for the EOR operations is supplied, via a 205-mile pipeline, by the Great Plains Synfuels Plant, in North Dakota, USA, operated by Dakota Gas. The company captures CO2 as part of its operations and has been exporting around 50% of its captured gas to the Weyburn and Midale oilfields since 2000. Overall, it is anticipated that around 40 million tonnes of CO2 will be permanently sequestered over the lifespan of the project - 30 million tonnes at the Weyburn oilfield and 10 million tonnes at Midale. EOR will extend the life of the Weyburn field by approximately 20-25 years.

Weyburn CO2 Monitoring Project

The project was launched in 2000 by the Government of Canada, the Government of Saskatchewan, Cenovus Energy and the Petroleum Technology Research Centre (PTRC) in Regina, Saskatchewan. The eight-year project, part of the IEA Greenhouse Gas R&D Programme, was extended to 11 years at a cost of $85 million. It is the largest full-scale CCS field study ever conducted and results include studying mile-deep seals that securely contain the CO2 reservoir, CO2 plume movement, and the monitoring of permanent storage.

The project has attracted 16 sponsors from government and industry that include IEA, Alberta Innovates, Saskatchewan Ministry of Energy and Resources, Japan’s Research Institute of Innovative Technology for the Earth, and 10 industry sponsors from Canada, the US, the Middle East, and Europe.

In July 2010, the US Department of Energy (DoE) and Natural Resources Canada committed $5.2 million to enable the project to conclude in 2011. The DoE provided $3 million and the Government of Canada provided $2.2 million.

Project coordinator, PTRC, is now using experience from this project to guide the Aquistore storage project (in Canada and US).

First Phase (2000-2004):

1. Geological characterisation of the geosphere and biosphere

2. Prediction, monitoring and verification of CO2 movements

3. CO2 storage capacity & distribution predictions and the application of economic limits

4. Long term risk assessment of the storage site

Findings

The natural geological setting seems to be highly suitable for the long-term storage of CO2.

The results achieved form the most complete, comprehensive, peer-reviewed data set in the world.

Additional research will however be needed to provide a more comprehensive conclusion.

Final Phase (2005-2011)

The end delivery of the Weyburn CO2 Storage Project is a Best Practices Manual. When made available, this will include technical components (including site characterisation, monitoring and verification, wellbore integrity and performance assessment), and policy components (including regulatory issues, public communication and outreach, and business environment).
