Weyburn-Midale Fact Sheet: Carbon Dioxide Capture and Storage Project

Company/Alliance: Cenovus Energy, Apache Canada, PTRC (Petroleum Technology Research Center)

Location: Weyburn Saskatchewan, Canada

Start Date: October 2000

Size: 1 Mt/yr: Over 20 Million tons injected since the project start

CO2 Source: Coal Gasification from the Great Plains Synfuels Plant near Beulah, North Dakota (The CO2 is piped to Weyburn EOR site in Saskatchewan Canada)

Storage: The CO2 is piped via an onshore 315 pipeline for EOR in 2 carbonate fields. Cenovus Energy owned Weyburn field (6,500 t/day) and Apache owned Midale field (1,200 t/day)

Motivation/Economics:

To increase oil production and CO2 EOR research. The 8 year project is estimated to cost $80 million. The U.S. and Canadian governments have jointly pledged an additional $5.2 million in new funding in July 2010. The DOE providing $3 million and the Canadian Government is provided $2.2 million.

Comments:

In January 2011 a report was released that Weyburn was leaking CO2 at the surface after gas bubbles, algae blooms and dead animals were found around a man made pond on a farm around the injection site. A private consultancy firm concluded that the CO2 was from Weyburn due to CO2 isotopic analysis. However pre-injection ground levels of CO2 have been shown to have the same isotopic ratio. The leaking CO2 is still being investigated if it could belong to the injected CO2.

The CO2 injection is in 2 sites, Cenovus Energy owned Weyburn field and Apache owned Midale field. The EOR has increased production from Cenovus's Weyburn field by 16,000-28,000 barrels a day and by 2,300 to 5,800 barrels a day for Apache's Midale field.

The EOR is expected to enable an additional 130 million barrels of oil to be produced and extend the life of Weyburn field by 25 years. Ultimately 20 million tons of CO2 are expected to be stored. Current cost $20/Ton of CO2. A 330 km (205 miles) long pipeline transfers the CO2 from Beulah, North Dakota, to the Weyburn field in Saskatchewan, Canada. There are 2 projects in tandem at the Weyburn field: The commercial EOR project run by EnCana; and the research project looking at the potential to store CO2, run by the PTRC. The research project was formally known as the International Energy Agency Greenhouse Gas Weyburn-Midale CO2 Monitoring and Storage project.
