Gail, I just bulled ahead inmy answer to you without looking at your links. You have my profound and sincere appology. I sometimes go off a little half-cocked, as i'm sure people on this website have noticed on occassion.
I'm not an expert on this type of recovery-in situ combustion-but I think it has a lot of promise. there are at least two serious questions that this type of production are going to have to answer, besides the cost;
What about the combustion products besides crude, CO2 and carbon monoxide? I know some of the CO2 is going to remain as a miscible solution, but surely some of its going to bubble off. And combustion yeilds othergases that will have to be captured and recycled or sequestered, carbon monoxide being one. Aren't there a bunch of poisonous metals in that stuff, things like arsenic and vandium? God, I wish I'd taken a course or two in chemistry instead of the short stories in Nathaniel Hawthorne in college.
Also, these processes are going to take a whole lot of hydrogen, commonly made from natural gas in chemical plants. How much methane is it going to take per barrel and where do the operators plan to get it?
I know the US Department of Energy did at least one study on in situ combustion of oil to produce some 17 or a
18 gravity oil at Saratoga in Hardin County, Texas on the supra-cap sands, but Mobil Producing of Texas and New Mexico shut it down as uneconomic in the early 1990's. Does anybody know where to find that study online?

They used a little natural gas and steam to get the thing started. They did have an energy draw in running the blowers non-stop, thus there were some operating costs not associated with steam injection. I remember gas is compressible, thus you need a pneumatic push to cause the oil to migrate towards the "toe". Forced air combustion has been done before with mixed results, many people abandoned it for steam and VAPEX type solutions.
That sounds great, I'd be very interested. Frankly , this sounds a little too good to be true.
Where's the hydrogen coming from to decrease th gravity of the crude? How many cubic ft a barrel? How do you make tar unto syncrude that will flow during the cold season. How about some photos and some photos of competing process aolutions ? Can you quote any Keats or Blake so I know you are an estheticially aware person? You know, just the usual Oil Drum Grilling.

I have talked to the person who sent me the links about doing a guest post. Maybe we will be able to ask some questions.
