Did we ever figure out the net energy from the sludge?

Fossil fuels are finite.
IMHO, in the long run (which is getting shorter all the time), it doesn't matter what wonderful new technologies are developed to get the oil out of the ground, the sea, the sand, or the shale.
The faster we get it out, the quicker it will run out.

I don't know the exact figures, but this Wikipedia article says the EROEI is approximately 5.4. It's still technically positive, but it's lower than the between 6 and 10 EROEI for the natural gas that runs the tar sands projects. That means you're still losing a lot of efficiency.
And of course none of this even remotely addresses the drain on the Athabasca River, or that huge tailings pond.

For their Johns that must...really suck...
If you want to mull over tar sand EROEI TOD have had a series of articles by Charlie Hall on various types of energy; here is the TS one: Unconventional Oil: Tar Sands and Shale Oil - EROI on the Web, Part 3 of 5. Like corn ethanol, unless tar can feed itself long term it's not going to save the day. Also like corn it has a ceiling on the volume it can deliver, and is at the mercy of economic conditions being just right.
Seems these monster oil companies are incapable of change. Of going Beyond Petroleum, you know?  Name the one horse drawn carriage manufacturer that evolved into an automaker. Answer: Studebaker.
THIS JUST IN: Court ruling spells delay for oilsands megaproject (also at Edmonton Journal):
| Quote: | CALGARY - Imperial Oil Ltd.'s $8-billion Kearl oilsands project in Alberta faces a major delay after a Federal Court judge on Wednesday turned down its request to have a key permit reinstated.
The permit, required to de-water the Kearl site, was pulled by the federal Department of Fisheries and Oceans after an environmental-impact assessment by a federal-provincial panel was deemed to be incomplete, the result of a court challenge by a coalition of environmental organizations.
Imperial, 70 per cent owned by Exxon Mobil Corp., asked Justice Douglas Campbell last week to exercise his discretion and restore the permit, arguing it had no fault in the situation, which was due to a minor error of law made by the panel. |
Kearn Ph. 1 was scheduled to come online in 2010, which is a quite lean year for megaprojects.

Well, at least fresh water is not a critical resource.

Oil Sands ER - (1.5 to 3) : EI - 1
Oil Sands (open pit mining) - ER (4) : EI (1)
Oil Sands (in situ) - ER(1.43) : EI (1)

OK, go build some nuclear power plants. Because...you know...they're so cheap and they go online so fast. They might come in handy 10 years from now, when Canada's NG production has fallen by 60%. But until that happens, tar sands production is limited by NG production.
In situ? Do you even know what you are talking about? The only in situ method I know of that doesn't involve the direct application of heat is VAPEX, and it's not even out of the testing stage yet.

Please do not confuse bitumen with oil sands.

Can you translate please?
When the projections are made regarding how much oil can be produced from this region, are the projections net or gross energy? I assume it is gross, but given how much energy is needed to produce this stuff, shouldn't there be a footnote or something?
What I am thinking is that the locals might say "yeah, for three million barrels a day we're okay with our comunity and local water supply being wrecked." If, however, they found out that the net energy was only 1.5 mbd, they might say "go look for oil somewhere else."

To put it in tiny tot terms:
If natural gas was the same price per BTU as oil there would be no bitumen nor oil sands production.

Hmm, it sounds like this project doesn't have a very bright future.

A good explanation for why using EROEI measures to determine the validity of an economic event is nonsense.

Nonsense? You're making another lame RGD joke, yes?
If the energy return on a remote or difficult product is negative than why use another fossil (or nuclear) fuel to extract it? Why not just use the primary fuel as a primary fool? Oh. I mean fuel. Oh excuse me 
So if you use up 2 million btu's of nat. gas to convert 1 million btu's of tar sludge to low-grade crude then you have wasted 1 million btu's of nat. gas. Right? Oh wait! you say. "I have converted the natural gas into something much greater---OCTANE FOR MY dumb crap CAR I am genius"
But in all seriousness your comment displays a complete lack of sophistication and worldlyness. Sorry I can't argue with you any more
