Rotorbent, as you said
The next guy put in CO2 injection and the oil is flowing again better than ever. And ours are as well.
Just a quick question about this. Does this mean you are increasing the CO2 in the atmosphere (after it dissapates) or storing the CO2 and reducing the amount of CO2 from the atmosphere. As long as they don't start injecting beer next.

Not pretending to be one of Rotorbrents theory guys, but my $0.02...
If CO2 is captured from atmosphere, or a source which would contribute to atmosphere it is reducing CO2 emission. Under pressure, even at moderate temps found deep down, CO2 sublimes into a solid. As long as well pressure is not released CO2 will stay down there until geological processes convert it into rock like Calcium carbonate (chalk).
Grew up in Houston, y'awl, so know how important oil biz is down Texas way - somethang had to power them big ole Saturns

My car back then got 12 mpg and my new diesel pickup gets 23 mpg so some change has taken place.
In the US, most people would be estatic to get over 20 mpg while in Europe most people would be horrified if they got below 50 mpg.
That comes from taxing the hell out of both the fuel as well as the engine size.

Why do Europeans buy cars that get better mileage than do US consumers? I think most of the difference is due to the price-elasticity of demand and tax policy.
Fuel costs a great deal more in Europe than it does in the US, and most of that difference is due to taxes. One reason that diesel engines are so popular in Europe is that in most countries diesel fuel is not taxed as heavily as gasoline.
Here in the US, diesel is often more expensive than gasoline. If a diesel engine costs $2000 more than a gasoline engine, and the fuel is 25% more expensive, then it is hard for a US consumer to make an economic case for a diesel engine.
IMHO, the best way for the US to increase the mileage of the fleet is to increase fuel taxes, rather than mandating fleet economy standards. It's easy to change what people want by manipulating the cost; it is harder to get people to buy what they don't want. Unfortunately, both the Democratic and Republican parties here in the US are allergic to raising fuel taxes.
The recent fuel price rises in the US have significantly changed vehicle demand in the US. Sales of traditional body-on-frame SUVs and full-size pickups are down significantly. Toyota's brand new full-size pickup truck already has $2000 on the hood to move it out the door.
It is going to take a while for the US fleet mileage to change, simply because people are not going to replace their vehicles overnight. In addition, the emission regulations are creating significant technical challenges for diesel engines.
But things are changing in the US.

Looks like Boeing is going with biofuel, according to this article at aero-news.net
Boeing, Virgin Atlantic Joining To Develop Biofuel
Wed, 25 Apr '07
Aircraft Fueled by Soybeans?
Virgin Atlantic CEO Richard Branson has entered into a partnership with Boeing to develop a bio-fuel for jet engines... and both parties believe they can fly a 747 with one engine running on biofuel as early as next year.
Normal aircraft movement contributes hundreds of tons of greenhouse gases to the environment. Branson (right) believes he has found the solution.
"The positive effects of biofuel will hopefully reduce or almost get rid of the airlines' contribution to global warming," said Branson.
Branson is joining forces with Boeing and aircraft engine manufacturers to try to turn everything from soybeans to switch-grass into jet fuel, according to WLS-TV Chicago.
Ground testing is scheduled to begin soon. A test flight could actually happen by the end of 2008.
"Passengers ill get from A to B on bio fuels the same way they get from A to B on dirty fuels. The difference is they'll be able to get from A to B without feeling guilty and without damaging the environment," said Branson.
"I think 15 years ago in the car industry people said it was unrealistic. Then with further work on fuel cells, ethanol, renewable sources and you can begin to see a future world out there where dependency is reduced," said Jim McNerney, Boeing chairman.
As Aero-News reported in December 2006, Branson lobbied Chicago Mayor Richard Daley to allow tugs to take planes from their gates to the runway and back at O'Hare. Pilots would only throttle up their engines for takeoff.
The tug system is currently being tested in San Francisco and London Heathrow. O'Hare currently uses tugs to move aircraft from gate to gate or from a terminal to a maintenance hangar.
A spokesperson for the Chicago Aviation Department denied any "serious" discussions about expanding the use of tugs.
"The footprint to the environment around those airports will be something like 90-percent better than it is today, a dramatic improvement. All the noise of those engines running all day will disappear," said Branson.

As I said. It's a culture thing - and here is the evidence 
..
Jeremy Clarkson (TopGear) testing the Humvee H1 and H2 on European roads ..

- madman
NB: Hummer H2 just went from 110.000 dollars to 150.000 dollars in Denmark last night. New taxsystem on vehicles just enforced, smacking huge gaseaters and lowering tax on small long mileage cars (for American, VERY small cars) ..
And the Hummer here is still only a 2 seater on yellow plates for that price, that is VAN's plates. Want all the seats in it (white plates like a normal car), you are probably gonna pay more than 200.000 dollars for it ..
And for those who would love to see 3 British funny aristocratic TopGear-men, driving some 800 miles out of Miami going north on a roadtrip in cars that cost no more than 1000 dollars, this is a great great laugh : http://www.youtube.com/watch?v=Na36aiBjmHQ

Fuel alternative
I am doing my bit, not for the CO2 lobby, because Im not buying the CO2 leading the global warming thing, but the reverse.
Its the cost of fuel , I am running a 2 ltr perkins on 55% rape oil £0.52 per litre for 57 mpg no mods to the vehicle, when it goes for MOT it is nearly off the bottom of the gas analyser reading. AS for taking food product away, seen how many fields are kept empty by EEC subsidies
The only downside is you keep getting a strange desire for a burger or fish and chips
