As mentioned in my previous post, it makes one wonder what is the real game. <br /><br />Canada warned about U.S. energy protectionism <br /><br />Canada needs to beware U.S. energy protectionism – including policies that insist this country adopt greenhouse gas emission regulations for its oil and gas industry while giving U.S. and offshore producers a free pass, says former Conservative environment minister Jim Prentice.<br /><br />In a speech delivered in Halifax on Tuesday, Mr. Prentice cited U.S. renewable energy strategies that discriminate against Canadian hydroelectric power from Quebec and Labrador, as well as proposed low carbon fuel standards, like the one in California that disadvantages oil sands companies while exempting heavy oil producers in that state.Ahttps://www.blogger.com/profile/08473545026240354773noreply@blogger.comtag:blogger.com,1999:blog-5235419263414453422.post-30353306564730171362013-04-30T18:53:29.786-07:002013-04-30T18:53:29.786-07:00Stuart, below are some CO2 emissions data taken fr...Stuart, below are some CO2 emissions data taken from a chart in a 2009 Cambridge Energy Research Associates report. It compares CO2eq emissions associated with the combustion of crude from different sources. Total emissions are for extraction, processing, distribution and combustion. The combustion portion releases 430 kg/bbl. CO2eq emission units below are in kg/bbl.<br /><br />U.S. average barrel consumed: 530<br />Steam Assisted Gravity Drainage: 600 (highest)<br />Nigeria country average: 590<br />California heavy oil: 580<br />Venezuela country average: 560<br />Synthetic crude from mining, average: 555<br />Mexico average: 535<br />Saudi Arabia light: 510<br />Kuwait average: 510 (lowest)<br /><br />The primary use of bitumen is to produce synthetic crude oil (SCO) not asphalt. One barrel of bitumen yields approximately 0.83 barrels of synthetic crude when heated in a coker to remove carbon, rather than adding hydrogen.<br /><br />The typical EROEI is typically around 5. It takes from 900,000 BTUs to 1,000,000 BTUs of NG to produce one barrel of SCO, 5,800,000 BTUs<br /><br />In today’s, Globe and Mail, the following appears: “Petroleos Mexicanos (Pemex) competes with Canadian heavy oil producers in the Gulf of Mexico, and its heavy Mayan crude is currently priced at $96 (U.S.) a barrel, $5 more than the trendsetting light crude, West Texas Intermediate, and nearly $30 more than Canadian heavy crude was fetching in the North American futures market.”<br /><br />This statement makes one wonder what the real reasons for opposing Keystone XL are. While the environment may be a consideration, given the numbers above, supplying trapped bitumen cheaply to American refiners may not be far behind.<br /><br />Ov<br /><br />Ahttps://www.blogger.com/profile/08473545026240354773noreply@blogger.comtag:blogger.com,1999:blog-5235419263414453422.post-52123482928224602962013-04-28T15:03:02.580-07:002013-04-28T15:03:02.580-07:00Yeah, and Jim Hansen call this "Keystone"...Yeah, and Jim Hansen call this "Keystone" approach "Neanderthal"...

The market for this product is assumed to be for cracking and refining to regular products. Alberta industry has stopped building upgraders for the bitumen because their local economy is so overheated with expansion of tar sand extraction.John Millenhttps://www.blogger.com/profile/12552860854685950957noreply@blogger.comtag:blogger.com,1999:blog-5235419263414453422.post-92043372952138702452013-04-26T12:54:07.219-07:002013-04-26T12:54:07.219-07:00Stuart, correct me if i'm wrong, but the pumpa...Stuart, correct me if i'm wrong, but the pumpable stuf is currently at 1 Mb/day, the road tar is the other 1 Mb. The bottom graph suggests what is pumpable through the pipeline, but only the liquid part will pumped, so your graph should be halved (maybe I am confused by the blue color of the graph)<br /><br />Do you think that there is a market for these huge amounts of bitumen? I think infrastructure investments will dwindle in the comming decades, making it questionable if all that tar will need to be produced.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5235419263414453422.post-29392963569653521222013-04-26T11:21:28.403-07:002013-04-26T11:21:28.403-07:00What I would like:
