Farmer says CO2 injected underground is leaking

From the “I told you so dept.” I knew it would happen, just a matter of when. Didn’t think it would be so soon.

A Saskatchewan farm couple whose land lies over the world’s largest carbon capture and storage project says greenhouse gases seeping from the soil are killing animals and sending groundwater foaming to the surface like shaken soda pop.

The gases were supposed to have been injected permanently underground.

Cameron and Jane Kerr own nine quarter-sections of land above the Weyburn oilfield in eastern Saskatchewan. They released a consultant’s report Tuesday that links high concentrations of carbon dioxide in their soil to 6,000 tonnes of the gas injected underground every day by energy giant Cenovus (TSX:CVE) in an attempt to enhance oil recovery and fight climate change.

Paul Lafleur of Petro-Find Geochem found carbon dioxide concentrations in the soil last summer that averaged about 23,000 parts per million — several times those typically found in field soils. Concentrations peaked at 110,607 parts per million.

Lafleur also used the mix of carbon isotopes he found in the gas to trace its source.

“The … source of the high concentrations of CO2 in the soils of the Kerr property is clearly the anthropogenic CO2 injected into the Weyburn reservoir,” he wrote.
