$this->bbcode_second_pass_quote('ROCKMAN', 'S')peaking of the Alberta oil sands NOT FADING AWAY here's an updated chart showing that with it's development Canadian oil production has almost doubled since 1990.
https://en.m.wikipedia.org/wiki/Petrole ... uction.pngOne should notice that oil sands production increased more then 500 MILLION BBLS PER YEAR during the period when oil prices ranged between $20 and $35 per bbl. Compared that FACT to the assertion that the oil sands are economical to produce at oil prices less then $50/bbl.
Excellent point. I first heard about the Alberta Tar Sands back in 1982 when a couple of the big USA oil companies were trying to develop methods for producing Green River Formation Shale by cooking the kerogen out of it and turning it into synthetic crude they could ship off to the refiners. At the time they were complaining because Canada was heavily subsidizing Alberta Tar Sands to produce synthetic crude aka Dilbit, and they were screaming about unfair competition mostly in an attempt to get USA government subsidies for their projects.
Now if Canada was producing something like 500,000 bbl/d of Dilbit in early 1982 and producing a lot more in 1995-2000 when world oil prices were remarkably low compared to today then claims the industry is dying at $50/bbl are clearly nothing but hype.
ROCKMAN I looked this thread up to ask you questions about Dilbit.
Would it be accurate to say Dilbit is manufactured by putting a quantity of dilutent into an empty tank, starting the stirring process and then gradually adding the heavy bitumen to the tank until the combined Dilbit has the correct viscosity to be shipped via pipeline?
Second, do the types of dilutent change over the year so that a thinner Dilbit is made in January and a thicker one is made in June because weather effects also impact viscosity?
Thirdly, If you have to make a lot of Dilbit is it more economic to just use more of whatever dilutent is cheapest, or carefully formulate the ratio so that you get a better sale price when it gets sold in Cushing?
Lastly, when you make Dilbit and then store it in one of those big tanks somewhere do you have to keep stirring it every once in a while to keep it from separating into heavy and light layers like a water/oil emulsion, or will it stay homogenized in perpetuity because all the components are hydrocarbons?
TIA!
