Tar Sands Mining: Well, Canada is sorta big right?

It is one thing to say that the Athabasca tar sands mining project is a behemoth- quite another to actually see it. Here at SkyTruth we have always recognized how powerful a story real-world images can tell.

Check out our newest addition of satellite “truthing” – A quick animation of the growing Athabasca tar sands mining “footprint” and future extent.
Big tip o’ the hat to Global Forest Watch Canada for providing the mining data.

We have placed the boundary of Washington, DC on top of one of the open-pit mine locations to give viewers a sense of just how vast this whole operation is. Have any of you ambitious tourists ever attempted to walk the length of the National Mall from the U.S. Capital to the Lincoln Memorial?

It’s farther than it looks (as my feet will attest) – about 1.9 miles to be exact. Now imagine that instead of strolling along green lawn you are  bobbing in the middle of a 4 mile wide industry tailings pond, full of sand and a host of known toxins. This distance, indeed the entire area of the District, is minuscule in comparison to the Athabasca extent.

Future mining extent and 2009 mined extent
And don’t forget the future, already approved extent of mining not yet begun. Or the much larger area of surrounding land used for in-situ, or on-site, extraction operations not shown in this animation; here’s a pic showing the landscape impact of in-situ development.

As citizens and policy makers alike gear up for the largest protest yet against the Keystone XL pipeline happening this Sunday, November 6 at the White House, it is important to remember that no event occurs in a vacuum. Approval of this pipeline will open up new markets for tar sands oil in the US, Mexico, Central and South America and Europe – and put this already vast mining and extraction operation on steroids.

Oil from sand? You better believe it.

Question: From which country does the United States receive the majority of it’s oil?
Answer: Canada! Not Saudi Arabia. Not Angola. Not Kuwait. Canada.
You would be very surprised by how few people know this crucial fact. Or maybe not that surprised, depending on how you answered the above question.
Fact is Alberta’s bituminous tar sands have rapidly become a burgeoning force in our oil-driven world. The oil itself is retrieved through “unconventional” methods, as the sands are mined and refined through various processes to extract bitumen and turn it into petroleum. Controversy is raging right now over the proposed Keystone XL pipeline that would bring much more oil from Alberta’s tar sands across the US to refineries on the Gulf Coast – possibly for export to Mexico, Central America and other markets. The U.S. recently began exporting more petroleum than we import.
Alberta has experienced a economic boom in only a few short years, shepherding job creation and wealth into the province. However, environmental protests against domestic tar sands expansion and subsequent impacts on local wildlife and the Athabasca River are gaining force. Although industry players draw support through proclamations that tar sands are more “ethical” compared to oil from the Middle East or Africa, carbon emissions from extraction and refining pose significant climate threats to all of us.
Regardless of the politics, the actual mining imprint on Alberta’s landscape is impossible to fudge, and getting harder to ignore. See SkyTruth’s Flickr page for satellite images of the Athabasca mines.

Believe it or not, these SkyTruth maps only show part of the impact of tar sands development – the area where surface mining is the preferred technique.  A much larger area surrounding this has been targeted for  “in-situ” exploitation, where steam is generated (by burning natural gas) and pumped into the ground, heating up the buried tar sands deposits until bitumen is liquified and can be pumped to the surface for processing. Here’s the landscape footprint of the in-situ process:


Infrastructure footprint of in-situ extraction of bitumen using the steam-assisted gravity drainage (SAGD) technique near Cold Lake, Alberta. Each bright rectangular patch is a cleared area about 6-7 acres in size where horizontal wells are drilled to inject steam and extract the bitumen for processing. Drilling sites are spaced about 0.2 – 0.5 miles apart.

Alberta’s Tar Sands: In-Situ Extraction Converted to Mining?

Canada’s massive Athabasca tar-sands mining operation in Alberta has been in the news, as the U.S. State Department nears a decision to approve or reject the Keystone XL pipeline.  This proposed pipeline would carry oil extracted from the tar sands through the heartland of the U.S. to refineries on the Gulf coast, where it would be processed and most likely exported to Mexico, and Central and South America.  (Fun fact: we already export more petroleum than we import here in the US, which is why the “energy independence” argument for more drilling is a bunch of hooey.)

Speaking of hooey: the extraction and processing of tar sands bitumen into oil has a very high carbon footprint and uses large amounts of fresh water.  You can read all about it here.

We’re watching the production end of this mess, looking at the steadily growing impacts in Alberta where the tar sands are being exploited, mostly by good ol’ fashioned mining but also by in-situ extraction of bitumen. Google Earth now has 2010 high-resolution imagery covering most of the active tar-sands extraction areas, just north of Fort McMurray, Alberta along the Athabasca River.  There is also a good database of historical imagery in Google, so you can do some interesting time-series analysis.

One thing we noticed – a 7,000-acre forested area of what appeared to be in-situ extraction since 2003 is now cleared and actively being mined.  Industry has been touting in-situ extraction as a more “environmentally friendly” way to produce the tar sands, but that’s just PR bull if they’re going to eventually mine it anyway.

Here are a few examples to get you started on your own skytruthing adventure of this leading environmental issue.  Let us know if you see anything interesting!

Same area as it appeared in 2005, using Google Earth “view historical imagery” tool. Area is mostly forested in 2005, but marked by regular grid of dirt access roads leading to small clearings that we assume are well sites for in-situ extraction of tar sands oil.  Compare with 2010 image below.

 

Recently cleared area in 2010.  Apparently in-situ extraction has been replaced by conventional mining. Area was still forested in 2006 but by 2008 logging had cleared most of the land, and conventional mining operations were underway.  Compare with 2005 image above.

 

Zooming in even further on the 2010 image, we can see details of the active mining that’s now taking place.

 

And here is what that same place looked like in 2005.
