Winnipeg Free Press;
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.
“We knew, obviously, there was something wrong,” said Jane Kerr.
However, this is not to suggest that all planet-saving sequestration projects are unsuccessful. There’s still no sign of Dorothy Halton bubbling to the surface.
Update, from the comments;
I am a geologist who mapped the Weyburn field at the time it was undergoing CO2 injection. There are multiple, layered reservoirs of dolomite, separated vertically by thin, non-permeable rock and limited laterally by facies changes and local erosional events. Where the gas goes cannot be predicted with any detail. It is possible that a portion has been jammed into one pod and built up pressures greater than the caprock could stand. There are also small faults that rise to the surface or near-surface, visible in seismic: an unsealed fault could be the problem here.
At the same time, the fellow dug a gravel pit. He could be releasing underlying “swamp” gas from buried post-glacial muds, sands and wood. There are also shallow coals below the glacial gravels: they could be the source of the gas. I’m more experienced in field foolishness to assume that old garbage dumps or local sewage ponds/tile-beds have already been ruled out.
The climate warmists blame CO2 for temperature rises as an argument from ignorance: if not CO2, then what? To blame Cenovus for the gas is similar in validity. C14 isotope and composition analysis will straighten this out. I suspect that we will find a surface source for the CO2.
By the way, the Weyburn injection is not a CO2 “sequestration” scheme. It is a tertiary gas-flood to obtain additional oil from an existing, but only partially-drained, oilfield. The gas is cycled back into the ground as more oil is produced. Ultimately, it may be left in the ground, but it might also be captured later for other oil recovery schemes. CO2 is far to expensive and useful to simply throw away.
I figured we’d hear from somebody about this, sooner or later. Thanks, Doug.
