I just read this article in the Globe and Mail:
http://www.theglobeandmail.com/servlet/ArticleNews/TPStory/LAC/20050921/RDILUENT21/TPBusiness/Canadian

It reports that:
Quote:
EnCana Corp. has come up with a solution to a big problem plaguing oil producers in Alberta, especially some of those in the oil sands, by arranging for major imports of diluent.

Diluent is a condensate -- a very light oil -- that is used to dilute "heavy oil" and bitumen, the super heavy crude that comes out of the oil sands, allowing the normally too-viscous product to flow through a pipeline.

Quote:
Current diluent production in Western Canada is about 200,000 barrels a day. EnCana said by 2015 the industry could need 500,000 barrels of the product. In addition to the 25,000 it plans to import, an EnCana facility in Alberta will be ready to produce 5,000 barrels of diluent by October, which together with the imports will increase the regional supply by 30 per cent.


Apparently, this diluent is usually produced from condensate from natural gas production, but I guess there's no chance of increasing that in North America any more, so it has to be imported. Now, I'm wondering just how much they will be able to ramp up production of "synthetic" crude oil from tar sands if this diluent is essential to the process? Will they be able to get hold of enough of it?

There are huge projects already up and running to transport LNG ( liquid natural gas ) . When compressing and releasing this LNG there is plenty of diluent extracted , either at source or in the harbour. India is buying now 25% of Shell's LNG bussines.
What is this "diluent " made of actually ? Could it be benzol ?

Another oldie but goodie! North America can't increase gas production any more!!

Isn't it amazing how the very fundamentals that were once assumed, have been dismissed by reality so thoroughly? And quickly?

Another unsurprising study about fossil fuel extraction.

Subheads:

Pollutants in the air
Pollutants in the water
Toxic air emissions during transport and loading
Diluted bitumen spills
Train derailments and railcar explosions
Refinery emissions
Noxious odors
Petroleum coke
Increased risk of refinery accidents


Quote:
Even without additional health monitoring data, enough is known now about this environmentally destructive and dangerous fuel source that the tar sands oil industry's plans to triple production by 2030 should be halted.
