BLM Meetings on Oil Shale and Tar Sands Development Surface the Water Issue

15 January 2006

The Bureau of Land Management, part of the US Department of the Interior, has begun public meetings to obtain comments for the programmatic Environmental Impact Statement (PEIS) required to support commercial oil shale and tar sands leasing on federal lands in Utah, Colorado and Wyoming.

Congress directed the BLM to complete the PEIS and initiate commercial leasing of lands for the production of strategic unconventional fuels in the recently passed Energy Policy Act of 2005.

For purposes of the PEIS, the planning area for oil shale includes the Uintah Basin (Utah), the Piceance Basin (Colorado), the Washakie Basin (Colorado and Wyoming), and the Green River Basin (Wyoming). For tar sands, the planning area encompasses certain sedimentary portions of the Colorado Plateau in Utah.

One of major concerns emerging about the production of oil shale is the water issue.

According to a report in the Salt Lake Tribune, a former Utah state science adviser estimated that 10,000 acre-feet of water would be needed to sustain a year of producing 100,000 barrels per day of kerogen.

(One acre-foot is a volume one foot deep covering an area of one acre. An acre-foot contains exactly 43,560 cubic feet, or about 325,851.4 gallons US. One thousand acre-feet (kaf) contains 325,851,400 gallons. The 10 kaf needed for 100 kbpd of kerogen per year would thus require 3.25 billion gallons of water per year.)

Earlier estimates (made during the prior oil-shale boom several decades ago) for water use in surface mining processing of oil shale range from one to three barrels of water for each barrel of kerogen. On that basis, 100,000 barrels per day of kerogen would require between 1.5 billion and 4.6 billion gallons of water per year. So the 10 kaf estimate from Utah basically splits the difference.

Further complicating the picture are the implications for surface and ground water quality.

The Denver Post reports that governments in Colorado and Utah are reviving plans drawn up more than two decades ago during the previous oil-shale boom for major reservoirs to feed shale production.

The town of Rangely is using an environmental study done during the late 1970s as a starting point for a proposal to build a 200 kaf reservoir. That study at the time determined about 500 kaf of White River water would be available for capture and reuse.

Using an in-situ process such as Shell has been working on (earlier post) would require less water than the surface method, but a more precise estimate of how much less is still under analysis.

The West has been in the grips of a drought that USGS scientists in 2004 characterized as the worst in 500 years. The drought, while ongoing, is forecast to improve a bit this spring.

Those areas contain some of the most pristine, undeveloped views left in the United States. Do we just have to spread our shit everywhere in order to give obscene profits to the lying oil barons?

Pardon my ignorance, but what's kerogen?

Kerogen is a solid organic precursor to oil and gas--from which oil and gas can be obtained through appliation of heat. Kerogen is to oil shale and bitumen is to tar sands.

Lucas - it is more that just "lying oil barons". We are driving this with our car choices. Really you can shoot this down by buying a smaller car (assuming you do not already own one), driving less or even campaign to get electrics or plug in hybrids.

"Do we just have to spread our shit everywhere in order to give obscene profits to the lying oil barons?"

Nice vocabulary dude.

"...worst in 500 years... (drought)"

I know the drought is bad, but didnt know the USGS kept records that far back!

I now feel electric, via nuclear/solar/wind/fusion, not fossil fuel, is the propulsion of the future.

""...worst in 500 years... (drought)" I know the drought is bad, but didnt know the USGS kept records that far back!"

Yep, they are incomplete, require a lot of ingenuity to find and are hard to read but the records are there. Google "Paleoclimatology".

Very scary stuff in those records, by the way.


Pardone my French. I sometimes tend to get pissed.

Yes - I am driving a 2004 Honda Civic Hybrid.

If you want to see what happens with these type of operations go to local google Fort Macmurry Alberta Canada. Just look at the scared land scape. I've been there and the smell and pollution are out of control. It has made a impression on me. I'm working on converting my vehicles to SVO and biodiesel. There just too much demand for black gold. It's like a Klondike gold rush all over again up there.

"Pardone my French. I sometimes tend to get pissed."

It was pure anglo saxon. Learn to control yourself, people are more likely to pay attention.

For more detailed information on tar sands extraction activities and environmental impacts, read a recent report (Oil Sands Fever) by Dr. Malo Raynolds (Pembina Institute) and Dan Waynillowicz et al available free from:

It makes you wonder if we are doing the right thing. Energy conservation and essential energy from alternative renewable sources would be much better for all of us.
