The Alberta Energy Regulator (AER) has released new figures tallying the total volume of bitumen emulsion recovered at the Canadian Natural Resources Ltd. (CNRL) Primrose site in Cold Lake, Alta. The new total — 1,177 cubic metres or 1.1 million litres — is more than a third lower than previously reported amounts.

An earlier incident report from November 14, 2013, states more than 1,878 cubic metres of emulsion was recovered at the four separate release sites, where the mixture of bitumen and water had been leaking uncontrollably into the surrounding environment for several months without explanation. That's enough liquid to fill an Olympic-sized swimming pool three-quarters of the way full.

CNRL's July 31, 2013, statement (pdf), released to investors just over one month after the leaks were reported to the AER, said that within the first month of cleanup, 1,000 cubic metres of bitumen emulsion had been collected.

Scientist Kevin Timoney, who's authored several reports on the CNRL leaks, said the reported figures just don't add up.

“The bottom line is, how do you go from essentially 1,900 cubic metres, which is what you get if you listen to the president of CNRL when he was talking in January, down to 1,177 cubic metres. How does that happen?" Timoney said. "And nobody has answered that."

Bob Curran, spokesperson for the AER, told DeSmog Canada the provincial regulator has no ownership of the volume amounts they report to the public and publishes figures given to them by CNRL without verification.

“Those numbers on that site are estimates. They are provided by the company. They are not confirmed AER numbers, nor have they ever been,” he said. “So if the company changes the estimate then we would change a number on the site, until such a time that we arrive at a final number. We haven’t done that in this case so those numbers continue to be estimates supplied by the company.”

Timoney said the U.S. regulator, the Environmental Protection Agency, would never rely on industry for that type of data. "They’d be out there gathering data and determining how much had been spilled and how much had been cleaned up," he said.

When pressed on the disparity between current reported figures and previously reported figures, CNRL spokesperson Zoe Addington said the difference was a matter of “reconciliation.”

CNRL has removed oil, processed water, fresh water, vegetation and soil from the site. Addington was unable to clarify if the decrease in recovered bitumen emulsion volumes was due to an increase in reports of removal of other materials, such as fresh water and vegetation.

A CNRL report states, “Numbers have changed since the last reporting period based on a reconciliation of volumes with the receiving facility.”

Timoney, an ecologist with Treeline Ecological Services who just released a new report this month called CNRL’s Persistent 2013-2014 Bitumen Releases near Cold Lake, Alberta: Facts, Unanswered Questions, and Implications (pdf), said he'd like to see the data.

"Reconciliation is a nice word, but show me the numbers," he said. "I’m a scientist so I really want to see how this comes about."

He said even the AER and CNRL's own figures at times don't match. In mid-January AER published the 1,177 cubic metre volume while CNRL was still posting 1,864 cubic metres.

"Since I can’t get on site and they won’t give me the raw data, I just really have to report what they say and point out when it doesn’t agree," Timoney said.

Canadian Natural Resources Ltd. images show the continued seepage of bitumen to the surface at location 9-21, the site of a water body now partially drained.

As a scientist, Timoney finds the lack of transparency dangerous, especially to the regulatory process. 

"This is one of the problems with the whole regulatory system, because … AER just simply reports, apparently reports, what industry tells them. They don’t do any checking."

Reproducing industry figures in the name of public disclosure isn't much of a solution, he said. 

"I think the regulator has a responsibility to provide an accurate assessment of the company’s activities. So if the regulator is not verifying information, it’s just simply acting as a clearing house for information industry gives it, it’s not doing its job. It’s not acceptable."

He added: "It’s a problem that’s only gotten worse over the years, in the sense that now AER is basically a non-governmental entity. It’s funded by industry. It’s not an agent of the crown so we don’t have the same sort of access to information we would if they were a government agency. So the AER can basically do whatever it wants to do and the public doesn’t have any recourse. It’s unbelievable, really, when you think about it."

CNRL says cleanup is now complete at three of the terrestrial seepage sites. The final site, 9-21, located beneath a body of water that has since been partially drained, continues to seep bitumen.

According to Addington: “Seepage from the fissures has slowed to an almost imperceptible rate.” CNRL currently reports the rate of seepage for all sites at less than one cubic metre (1,000 litres) per month.

The ongoing seepage of bitumen emulsion – a mixture of heavy tar sands oil and water – on Canadian Natural Resources Ltd.’s (CNRL) Cold Lake operations is now reportedly occurring on six sites, up from a previously reported four.

The two new sites were identified by the Cold Lake First Nation, according to a press statement released early Monday.

“Our people want answers and factual information on the contamination of now, six surface releases of bitumen oil,” said Cecil Janvier, Council Member and Media Spokesperson for the Cold Lake First Nation.

The Cold Lake First Nation says they want greater involvement in the ongoing release of oil on their traditional Treaty 6 territory and suggest that they have been left in the dark by CNRL.

High-pressure cyclic steam stimulation or HPCSS is used by CNRL to fracture underground rock and heat up deep reservoirs of bitumen, allowing a resulting mixture of bitumen and water to surface up a wellbore. In CNRL’s current operations several uncontrolled fissures are leaking bitumen above ground, possibly due to unintended fractures below. The company claims the mechanical failure of a wellbore is to blame, although the Alberta Energy Regulator (AER) states there is no known cause for the ongoing leakage at this time.

Multiple investigations into the cause of a similar 2009 underground release were inconclusive, although the Energy Resources Conservation Board (now AER) stated “a contributing factor in the release may have been geological weaknesses in combination with stresses induced by high-pressure steam injection.”

The current series of underground leaks have forced more than 1.4 million litres of bitumen emulsion to surface on the ground and in a body of water near the company’s operations. The leaks are still uncontrolled at this time.

“I'm really distressed about the safety of our drinking water, animals, vegetation and how this is affecting the aquifers underneath our Dene lands. Our future generations will not be able to enjoy what once was pristine Denesuline territory. Animals such as wolves and bears are now migrating through our community, which is a safety risk and precaution. The environment is changing and definitely not for the positive,” stated Chief Bernice Martial in the press release.

CNRL investor relations spokesperson Zoe Addington contradicts the Cold Lake First Nation’s claims, saying “there have been no further discoveries of bitumen to surface.”

“Canadian Natural Resources Limited reported that bitumen emulsion was discovered at surface at four separate locations. The discoveries were immediately reported to the Alberta Energy Regulator and concurrently crews were dispatched to initiate necessary action. Each location has been secured and clean-up, recovery and reclamation activities are progressing well. Regular updates can be found on our website at: www.cnrl.com,” she told DeSmog Canada in an email statement.

Currently CNRL is the only body reporting on the rate and volume of the release. The AER, the province’s main oil and gas industry regulator, is reporting CNRL’s figures on its website.

“These numbers are not absolute, they’re not final,” says Bob Curran from the AER, “they may be adjusted as new information comes to light.”

“They’re not indicative of anything except the fact that they’re being updated at this point. I don’t know how much stock you can put into them other than we’re updating information with the information that we’re given as quickly as we can.”

“These aren’t numbers that we’re saying we’ve 100 per cent verified but these are number that are being reported to us. I think there’s an important caveat on that,” he said.

Curran says that it is normal for industry to report its own figures in an instance like this. “We certainly try to verify those figures but yes it’s their facility, it’s their issue that they have to deal with. Our role is to ensure they are responding appropriately.”

The AER has released several updated incident reports on the leakage as part of its larger effort to provide information on “energy-related incidents that may impact the public,” their website states.

The AER first reported on the incident on June 24th, claiming 28 cubic metres of bitumen were released. The most up-to-date figures, released September 6, 2013, claim that more than 1444 cubic metres, or more than 1.4 million litres, of bitumen emulsion have been recovered so far from the uncontrolled seepage.

Canadian Natural Resource Limited (CNRL), the company responsible for a massive ongoing spill on the Cold Lake Air Weapons Range southeast of Fort McMurray released a public notice last week claiming the release was “secured” and that “clean-up, recovery and reclamation activities are well under way.”

Cara Tobin, Office of Public Affairs spokesperson for the Alberta Energy Regulator, said that CNRL has yet to bring the release under control. 

The spill, caused by a rare underground spring of bitumen emulsion, is the result of High-Pressure Cyclic Steam Stimulation (HPCSS) technology that forces steam into underlying bitumen reservoirs at temperatures and pressures high enough to fracture underlying formations.

“I don’t want to presume what they mean by [secure] but I can tell you a few things that might help clarify,” she said.

Under usual circumstances with HPCSS heavy bitumen is softened by steam injected under the surface, allowing the resulting water and oil mixture – called bitumen emulsion – to surface up a wellbore. In this instance the high pressures underground are creating multiple bitumen springs, forcing the oil mixture to the surface in numerous locations including under a body of water.

“With any incident the company would go to the site and identify the outer boundaries of the affected area,” Tobin said.

“There’s two things – one is control and one is containment. What they have done, to the best of my knowledge, is that they have identified the outer extent of the impacted area, which is generally called delineation. I think they were finishing that process [Friday]. And so they are getting to know and rope off the outer extent of the impacted area.”

“So that’s one thing. And that’s basically containment…In this case, this is still an ongoing incident. There is no control on this incident.”

According to CNRL the area of initial impact is 20.7 hectares, or just over 51 acres. The spill volume to date, initially reported at 28 cubic metres, was updated to 950 cubic metres, or nearly 6000 barrels of oil, over the weekend.

“In this case because the incident is ongoing there will continue to be more volume of product coming up to the surface but it’s not going to be impacting any vegetation [other] than what’s already impacted…There will still be more volume of product but it’s not going to be spreading further,” she said.

She added that although this spill is “relatively unique,” an incident of its kind occurred previously on the same CNRL site.

“It’s not like it hasn’t happened before though. We have information on our website, about a similar incident that happened in 2009 and it was the same sort of thing where pressure pushed bitumen to surface and until that pressure was naturally able to recede underground the product continued to – very slowly – come to surface.”

Much like the 2009 incident, the cause of the current spill remains unknown and it is not expected to stop until underground pressure subsides.

“What we’re seeing in this one is that pressure has built up underground and is finding ways to come to surface and we don’t know what the cause of that might be. That will come out in our investigation report. But regardless, it is coming to the surface, very slowly, and it won’t stop until that pressure has gone down underground,” Tobin said.

The rate of the spill remains unreported at this time.

According to documents from the former Alberta Energy Conservation Board (ERCB), now the Alberta Energy Regulator (AER), the 2009 release prompted the shut down of the site after bitumen emulsion was seen flowing out from the ground and pooling on the company’s Primrose East site.

A report on the incident says the bitumen emulsion could be observed seeping out of the ground to the south and the east of the well pad, as well as from surface fissures in the area.

The company initiated “emergency flowback to depressurize the formation” in an attempt to stem the release.

“Approximately 11,380 tonnes of solids (including snow, organic material, soil, and bitumen) was ultimately removed from the site for landfill disposal, and 904 cubic metres of bitumen was recovered from the surface of Pad 74 and transported to CNRL’s Wolf Lake Plant,” states the report.

Multiple investigations into the incident over the span of one year were inconclusive and could not ultimately determine how the bitumen emulsion made its way to the surface. The ERCB cited pre-existing unground fractures or a wellbore breach as possible explanations.

In its final summary the ERCB stated “a contributing factor in the release may have been geological weaknesses in combination with stresses induced by high-pressure steam injection.”

HPCSS creates fractures in underground formations to separate bitumen from sand. An AER incident report on the current CNRL release in Cold Lake describes HPCSS as a high-pressure steam injection method that fractures the reservoir to “create cracks and openings through which the bitumen can flow back into the steam-injector wells.”

"We don't know what the hell is going on under the ground."

That's what Crystal Lameman, a member of the Beaver Lake Cree Nation recently told me. On June 27, an oil spill occurred at Canadian Natural Resources Limited's (CNRL) Primrose operations 75km east of Lac la Biche. The spill happened on the Cold Lake Air Weapons Range (CLAWR), located in a region The Royal Canadian Airforce calls "the inhospitable wilds of northern Alberta and Saskatchewan." This 'inhospitable' region happens to be in her community's traditional hunting territory where her family traditionally hunted and trapped and where her elders are buried.

DeSmog Canada reported a release of bitumen emulsion, a mixture of heavy tar sands crude and water from in-situ (in ground) oil production.

Lameman told me she only heard about the spill from the press release from the Alberta Energy Regulator (AER). "It was disheartening to open my Facebook and see a link showing me the spill in our traditional hunting territory – that I had to get the information from an outside source as opposed to the information coming directly to the community."

The press release is sparse on details, but confirmed that that neither the company nor the government are certain of the volume of emulsion spilled, that the affected area is near Pad 22 but off lease, and has impacted a nearby slough. According to the release, the company has begun clean-up operations. But Lameman heard from source on site that the damage of the spill it much worse than the company, government or media are reporting.

"I was being told, there's wildlife still drinking from the water." She was also told that the 'slough' in question was actually a lake, but the lake has receded so much that industry and government are calling the lake a slough to minimize the perception of the spill. "That concerned me," she says, "and it made me want to go out there and survey the damage." And so Lameman decided it was time to find some answers. We set off to the Cold Lake Air Weapons Range, about 45 minutes east of her community.

The Journey

We pulled up to the security gate of a military base. Though I'd heard it was a weapons range, it still surprised me to see the high security and tar sands operations right on the base. Lameman was immediately denied entry and told that she needed to seek permission from an Aboriginal Liaison officer to enter the grounds, on her own traditional territory.

"I was told later that I won't be allowed in either way," Crystal tells me. "These are just the channels I have to go through. We pulled away and I just felt this sense of depression. After all this time we are still having to ask permission to utilize our land. How we walk on the land – we're still being told that, where we can and can't go."

Crystal Lameman of the Beaver Lake Cree Nation.

While regulatory bodies like the ERCB, AER, Fish and Wildlife and the federal government are monitoring, surveying, and testing, Crystal confesses, "It's scary that they're doing whatever they can to deny us access. It makes me wonder, what's happening to those beings who can't talk for themselves? How bad is it? What is it? I don't feel good about it."

Unfortunately, this isn't the first time the Beaver Lake Cree have been denied access to their own traditional territory. In 2008, they launched a lawsuit claiming that the cumulative effects of tar sands development interfere with their constitutionally-protected treaty rights to hunt, trap and fish. The nation is fighting for access to the CLAWR. Recently, a decision of the Alberta Court of Appeal rejected Canada and Alberta's attempts to have the case thrown out. 

Legal counsel for BLCN, Drew Mildon, noted: "First Nations have the strongest environmental law tools at their disposal in Canada." He went on to add that "this 'emulsion' spill is a perfect example of local impacts of the tar sands; unfortunately, the rest of us must rely on small, poverty-stricken First Nations to take courageous stands to stem the global impacts that are the debt we will pay for further tar sands development."

"Black Puddles"

According to Lameman's source, the damage was described to her as "black puddles" or "black spots" coming up in different areas. An employee on site confirmed that the tar sands emulsion seeping from the ground is not a pipeline spill. What's more, industry and government do not even know what the spill is. They also know there's a lot of oil seeping, and they don't know what it's coming from.

"The ground seepage is off-lease," says Lameman. "And the fact that they're scrambling, trying to figure out what happened, and trying to keep us out of there as much as they can validates the information I was given that this spill is worse than what they're telling us."

According to information obtained from an employee, the contaminated lake in question is likely near Burnt Lake, possibly at Ward Lake.

Whither CSS?

CNRL's Primrose site uses a kind of tar sands extraction called Cyclic Steam Stimulation, or CSS.

According to CNRL's website CSS is a three stage thermal recovery method where steam is first injected into the well at temperatures over 300°C and pressures of 10-12 Mpa (1450-1740 psi). This heats the bitumen in the reservoir, reducing the viscosity so that it can flow. The steam is then left to 'soak' before production begins for several weeks, mobilizing cold bitumen, and then the flow on the injection well is reversed, producing oil through the same injection well bore.

CSS diagram from Slideshare presentation, CSS Technology for Heavy Oil. 

The CSS process is only able to typically recover approximately 20% of the oil in the ground.

CSS as a process is relatively new, having been developed by Shell by accident in Venezuela after one of its steam injectors blew out. The process is becoming more common in the San Joaquin Valley of California, the Lake Maracaibo area of Venezuela, and in the tar sands.

According to ESG Solutions, a microseismic monitoring company that monitors oil and gas development, the CSS process is:

"environmentally sensitive and many risks exist … Well casings are subject to severe tensile stresses due to the high temperature, high pressure nature of the CSS process. These stresses have the potential to result in mechanical failures such as cement cracks or casing shear leading to well downtime, damaging spills or hazardous blowouts. Shear stresses also develop during the dilation of the reservoir during the steam injection, potentially causing the incursion of fluids into the overlying shales and aquifers above the caprock and causing environmental contamination and costly clean up and regulatory penalties."

Of CSS, Lameman says: "This is a whole new kind of oil mess that no one's really ever heard of in terms of tar sands production. Everyone's heard of pipeline spills and open pit mining. But I don't think the public has been told of the dangers of CSS."

Mining on an active military testing site?

The apparent dangers of CSS and the fact that seismic monitoring is needed to oversee the process are heightened when you consider that CNRL's Primrose facility operates on an active weapons testing facility.

The Cold Lake Air Weapons Range construction began in 1952 and was chosen by the Royal Canadian Air Force to be the country's premier air weapons training base. The base land in Alberta and Saskatchewan covers an area of 11,700 square kilometres. While the federal government worked out an agreement with other First Nations who were systematically pushed out of the area, Lameman's ancestors were banned without consultation or compensation.

CLAWR is said to be the "northern equivalent" of the United States Air Force's Nellis Air Force Range. It hosts over 640 actual targets and 100 realistic target complexes, including 7 simulated aerodromes with runways, tarmac, aircraft, dispersal areas and buildings, as well as mechanized military equipment such as tanks, simulated radar and missile launching sites, mock industrial sites, and command and control centres.

According to the Cold Lake Air Weapons Range website, "the Air Force conducts live fire training exercises on the CLAWR" and it appears that live fire operations are taking place this week.”

In addition to CNRL, Nexen, Husky Energy, Enbridge, Interpipe and Cenovus operate on the CLAWR.

Range activities officer at the CLAWR, Dick Brakele, says "to mix an active oil industry and an active weapons range where weapons are dropped takes a lot of imagination sometimes to ensure that the needs of both are met."

Imagination is one way to look at it.

I met up with Naomi Klein who was also reporting in the area. She told me: "Canadians should be shocked that our government is dropping test bombs in the same geographic area as massive tar sands operations. This is already the most dangerous form of fossil fuel extraction on the planet from an ecological perspective. Combining that mining with weapons testing – no matter how careful the players claim to be – is so reckless it verges on the surreal."

"This is something that everybody needs to know about."

Lameman still has a lot of questions she needs answered. To the oil companies and government she asks, "What is the magnitude of this spill? What is it? How much of the water has been affected? Did you stop it yet?"

For now, she has few answers. But the single mother of two isn't going to give up.

"This is something that everybody needs to know about because though it happens to fall within our traditional hunting territory, there's just as many non-native people as Indigenous people in this area. All of the water systems are connected. If you drink water, this is about you."
