Claims of leaking[edit source | editbeta] (Go to website for Links)
A report[2] of CO2 leaks above the project was released in January 2011[3] by an advocacy group on behalf of owners of land above the project. They reported ponds fizzing with bubbles, dead animals found near those ponds, sounds of explosions which they attributed to gas blowing out holes in the walls of a quarry. The report said that carbon dioxide levels in the soil averaged about 23,000 parts per million, several times higher than is normal for the area. "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... The survey also demonstrates that the overlying thick cap rock of anhydrite over the Weyburn reservoir is not an impermeable barrier to the upward movement of light hydrocarbons and CO2 as is generally thought." said the report.[4]
The PTRC posted an extensive rebuttal of the Petro-Find report, stating that the isotopic signatures of the CO2, claimed by Mr. Lafleur to be indicative of the manmade CO2 being injected into the reservoir, were in fact, according to studies of CO2 conducted by the British Geological Survey and two other European Union geological groups prior to CO2 being injected at Weyburn, occurring naturally in several locations near the Kerr farm. Subsequent soil surveys after injection in 2002 to 2005 found CO2 levels dropped in these same regions. In addition, prior to injection occurring into the oil field, these samplings were found to be as high as 125,000 parts per million and averaging 25,000 ppm CO2 across the region, even more than the average and largest readings from the Kerr's property that were being claimed as unusually high. The report also questions, based on seismic imaging conducted over ten years, that any active faults exist or that the caprock is compromised to allow pathways for the CO2 to reach the surface.[5] The PTRC acknowledged that they do not monitor the entire site for leaks, rather primarily above the part of the Weyburn field where CO2 is injected and key locations outside it, but the organization did monitor the Kerr's well between 2002 and 2006, finding no appreciable difference in water quaility.[6] They have also acknowledged that PTRC is a research organisation rather than a regulator, and manage the IEA GHG Weyburn-Midale CO2 Monitoring and Storage Project on behalf of the International Energy Agency's Greenhouse Gas R&D Programme, which includes some 30 international research groups.[7]

More Fizz to Saskatchewan Carbon Storage Controversy

Group overseeing project says it will refute study saying CO2 is bubbling back to surface.
By Andrew Nikiforuk, 19 Jan 2011, TheTyee.ca
A report that documented lethal levels of carbon dioxide in a farmer's field on top of a national $80-million demonstration carbon storage project in Saskatchewan has generated a storm of controversy, denials and calls for a more studies.
The Petroleum Research Technology Centre, a Regina-based industry and government research group overseeing the international project, says it will issue a technical report today, refuting the independent study. (When released, the report will be here.)
"We don't agree with the findings," says Steve Whittaker, the senior project manager for the IEA Weyburn-Midale Carbon Capture and Storage Project. "There are some significant deficiencies. It's a chicken little report."
But he admitted that monitoring for the project has been intermittent and only covers a fraction of the study area. "We're not a regulator. We're a research group." Whittaker also confirmed that there is no annual surface-monitoring program for CO2 leaks.
Billions spent pursuing sequestration
The Weyburn project, the world's largest full scale field study on capturing, injecting and storing carbon underground, represents a consortium of oil companies and oil exporting governments keen on proving the safety of burying carbon underground.
Both the Canadian and Alberta governments have devoted billions to the costly technology and want to build six or five demonstration cemeteries in Western Canada.
But the Weyburn project is also the only storage experiment where CO2 is also used to enhance oil recovery from an aging oil field. Cenovus Energy, formerly EnCana, injects up to 6,000 tonnes of CO2 a day from a coal-fired plant in North Dakota, to force out more oil from the field.
Most oil fields that inject CO2 (the gas works like a paint thinner) aren't regarded as safe or secure, explains a 2010 U.S. Department of Energy report, "due to missing operational and CO2 monitoring elements that are critical to demonstrating the effectiveness of the process for safely isolating CO2 away from the atmosphere for the purpose of addressing climate change."
High CO2 levels reported
Last week, a report by Paul LaFleur of Petro-Find Geochem found extremely high levels of CO2 (110,000 ppm) during a gas soil survey, or enough to asphyxiate a human. It also matched the fingerprints of the carbon on the farmer's property to that being stored in the giant Weyburn reservoir.
LaFleur and the environment group Ecojustice did the study last year after Cameron and Jane Kerr, a retired farming couple, complained about dead animals, foaming water and explosions at a gravel pit on their farm beginning in 2004.
The Kerrs say that the Saskatchewan government promised a yearlong study in 2007, but never delivered.
Normal levels of CO2 above an oil field range around 5,000 ppm, says Lafleur. He suspects the CO2 on the Kerr property is leaking via a fracture somewhere in the storage site.
"I'm not for or against carbon capture and storage," adds Lafleur. "It's up to the people and government what they will accept in CO2 leakage and what they can live with. Transparency is the key."
To date, only 5 per cent of the 110 square mile oil field has been monitored and LaFleur says that's inadequate. Nor is the Kerr property included in the monitoring area. "The facts speak for themselves."
Global interest in Saskatchewan project
Whittaker confirmed that very little monitoring took place between 2004 and 2008. Between 2000 and 2004, his research group performed the bulk of the monitoring including background CO2 readings as well as surface water and seismic testing. "We are trying to figure out what a good monitoring interval looks like." He says the project plans to do a soil gas survey this fall.
However, a Regina-based group called the International Performance Assessment for Geologic Storage of CO2 (IPAC-CO2) also announced that it will put together a team of experts to investigate the findings of the Lafleur report.
Created by Royal Dutch Shell and the government of Saskatchewan, the research group has a mandate to demonstrate the safety of the controversial technology.
In addition, Bellona, an international Norwegian environment group that supports carbon storage as a solution to climate change, also has supported the need for a thorough investigation.
Fault leakage a 'remote possibility'
Whittaker characterized Lafleur's claim that CO2 was probably leaking up through faults or fractures as "an extreme and remote possibility."
One of the goals of the Weyburn project is to provide policy-makers with reliable information about the security and safety of carbon capture and storage.
Experts in carbon capture and storage acknowledge that techniques to properly measure whether or not a storage site is leaking are still in their infancy.
Carbon storage professionals (yes, they even have their own academic journal) all agree that leaks from wells, abandoned facilities or faults can compromise the security of carbon storage sites and pose a health risk to humans and animals. But they also admit that no real system yet exists to locate and quantify surface leakage.
Invisible subject
Because CO2 absorbs light at specific wavelengths, U.S. researchers are now experimenting with optical detection techniques. None appear to have been deployed yet at Weyburn despite its international profile.
One study by the U.S. Lawrence Berkeley National Laboratory recently concluded that "detection of potential CO2 leakage will be challenging" due to the large ground area that needs to monitored, as well as extreme variability in CO2 levels from the soil.
Carbon capture and storage has ignited controversy around the world. Energy economists call it wasteful and fiscally irresponsible technology, while coal and oil companies argue it will extend the oil age. Some environmentalists favor the unproven technology, while others say the money would be better spent on renewables instead of dead-end storage facilities.

PREMIER BRAD WALL WELCOMES VISIT BY SENATOR HEIDI HEITKAMP
[

News Release - August 29, 2013
North Dakota Senator Visits World-Leading Carbon Capture Project
Premier Brad Wall today welcomed the visit by Senator Heidi Heitkamp (D-ND) as she toured SaskPower’s Boundary Dam Project near Estevan.
“When I met with Senator Heitkamp in Washington back in March, she expressed a great deal of interest in the Boundary Dam Project,” Wall said. “I’m glad her interest and enthusiasm for this groundbreaking project has continued and I welcome her to our province.”
Boundary Dam is the world’s largest commercial-scale coal fired carbon capture and storage (CCS) facility. Construction began in May of 2011. The project continues on time and on budget, with commercial operations set to begin in April of 2014.
On completion, the CCS technology at the plant will reduce emissions by up to 90 per cent. The CO2 captured at Boundary Dam will be used for enhanced oil recovery, or stored in a deep saline formation at the Petroleum Technology Research Centre’s Aquistore Project.
“With the federal and provincial investments in carbon capture technology to date, I can think of no other jurisdiction in the world that is beating Saskatchewan’s per capita investment in advanced clean energy technology,” Wall said. “This project is a great example of just how serious Canada and Saskatchewan are when it comes to controlling greenhouse gas emissions.”
A recent report from the International Energy Agency (IEA) states coal fuels 42 per cent of global electricity production and is likely to remain a key component of the world’s fuel mix for electrical production in the future, especially in developing countries. The IEA says CO2 capture and storage will have a significant impact on both existing and future plants. -30-
