What's The Word On CO2 (Waterless) Fracturing ? ?
Praxair does it.
They say it works great.
Since it's already in the atmosphere wondering if there is a way to filter it out, capture it and to then use it in waterless fracturing applications (for instance) instead of generating more ? ?
Read of a process that uses 'amines' to capture free atmospheric CO2.
Economics ? ?
Trees use CO2 and expel oxygen for our life sustaining use.
What's up with not using it more often ? ?
Why don't we hear about / read about / see more about it's application ? ?
Could 'politics' be delaying the game as far as it's use is concerned ? ?
Lots of 'politics' in the media these days - no ? ?
Maybe it's a case of not using it 'just for right now' ? ?

Thinking a sequence along the lines of 1) Capturing atmospheric CO2, 2) Using it to develop Natural Gas / CO2 Fracture new Wells, 3) Recovering as much as would be possible from such a production process, 4) Maximizing the use of Natural Gas instead of less clean burning fuels (such as Coal / Diesel / Gasoline); and all thereby not adding additional CO2 to the atmosphere but, rather reducing the amount currently being dispersed.
Have read the emissions rate has already been reduced by about 30% due to Power Plant conversions (from Coal to Natural Gas) in some area(s) (I think) in Pennsylvania.
How feasible a scenario would that work out to be I'm wondering

Fracking with CO2 to replace water a distant goal, GE says
NISKAYUNA, New York, April 7 |NISKAYUNA, New York, April 7 Carbon dioxide, used for years to force crude oil out of old wells, likely will not replace water in fracking anytime soon because of technical challenges and limited infrastructure, says General Electric Co , which is studying the issue under a $10 billion research program.
The delay means energy companies will continue to use more than 2 million gallons of water for each fracked well, equal to baths for some 40,000 people, stressing water supplies in arid American states and likely delaying fracking's expansion to western China and other water-stressed regions.
GE, which is making a push into oilfield technology, is studying how a chilled form of CO2 known as a "super-critical fluid" - neither a liquid nor a solid - could be used as the new industry standard for hydraulic fracturing, the process commonly known as fracking.
The conglomerate is working on the project with Statoil ASA , the Norwegian oil and gas producer, as part of its ecomagination program, which also is focusing on gas turbine efficiency, wind blade design and other energy projects.
"Our ultimate vision is to have a fracking process that uses no water, but we're a ways off from that," Andrew Gorton, a GE mechanical engineer leading the project, said during a tour of the company's research facilities in upstate New York.
The hydraulic fracturing of rock, or fracking, has allowed the global energy industry to access vast new supplies of oil and gas. Fracking opponents see a range of potential environmental damage from the process but are cautiously optimistic that using CO2 instead of water could reduce those risks.
CO2 fracking was used on a small scale in the 1990s by the company Canadian FracMaster before it filed for bankruptcy protection. Engineers say they want to figure out how to widely replicate the process across many different geologies.
Researchers are also trying to find the best viscosity, or thickness, for the CO2 at its chilled state to carry proppant, a type of sand that holds open cracks in rock so oil and natural gas can escape, much like water does in current methods.
"The hope is we can find a way to do it," said Mark Little, GE's chief technology officer.
Studies have shown wells fracked with CO2 tend to produce more oil or natural gas from the outset because CO2 fracks tend occur at a higher pressure than ones that use water.
Safely and cheaply transporting CO2, a compressible gas, on trucks to remote wells is also a concern where pipelines lag.
GE is separately studying with the U.S. Department of Energy how coal-fired power plants could best capture CO2 emissions and use the gas in fracking and other uses. GE and Statoil currently get CO2 from industrial gas suppliers such as Linde and Air Liquide.
Collecting CO2 as a power generation byproduct and using it to frack would reduce greenhouse gas emissions. But fracking would turn CO2 from a chilled fluid into a gas, and GE says it needs to devise a way to trap that gas back at the wellhead.
Ideally, a well's owner would be able to re-use CO2 at the next well it fracks, since nearly all CO2 injected would return to the surface. By contrast, energy companies cannot re-use most of the water today used to frack, though some recycling projects are trying to address that.
For years CO2 has been injected into old, conventional wells in places like California to boost pressure and increase the amount of oil that can be pumped out. This process is much less complex than using CO2 for fracking, as it doesn't require the CO2 to carry sand or other chemicals.

DOES THIS ANSWER YOUR QUESTION.......I little research will get you your answer but some people don't know how to use the net.... but live on a hope a prayer and a dream
propane gel fracking has not proven profitable either at a cost of 20 million per well in southern ohio

For information and in reply :
I use the internet regularly - GMS / this resource is for the most part a means to use the internet very efficiently - I tend to visit these pages and employ this sites efficiency most regularly in matters of oil and natural gas development as it is an ever changing continuously updating specialty field and in recognition that none of us can know everything - I intend to continue using it and sharing thoughts with those that are also interested in doing so - however the efficiency of this site is many times undermined by wise cracking wiseguy know-it-alls who I think actually do think they do know it all - I believe in this very exchange I'm conversing with one of those wiseguy wise cracking individuals.

so did the info answer your question ????????

For a goodly portion.
Still want to know more about the technique's application and possible future improvements - such as free atmospheric CO2 collection which would in no way contribute to the amount of free atmospheric CO2 - which many site as a pollutant greenhouse gas - but, which we all also should know is necessary for plant life / photosynthesis.
BTW - me and mine have lived this long by working for it.
There are hopes and dreams too.
Do you have any ?
I would bet you do.

CO2 is not a "greenhouse" gas. It is a natural element of nature necessary for life on the planet.

Natural element it is but there are those that have been labeling it a greenhouse gas pollutant.
Guess I fell into their trap.
Don't think I'm the 1st one however.
It's the anti carbon bunch.
Carbon is representative of life as we've come to know it in the many forms that abound on our planet.
Not a dirty word in my books.

Joseph,
I wasn't being critical of you or your statement.
I wanted the leftist environmentalists that read these posts to see my comment.
If these nut jobs were serious about the issue then they would all stop breathing, we (humans) exhale CO2.

Do you know of anyone other than GE working on using CO2 to fracture O & G wells ?
Have you read or have you learned of any R & D pertaining to the capture of (free) atmospheric CO2 for use ?

Still say Giddyup on Waterless Fracturing whatever the inert medium - but Free CO2 capture and use seems like a great place to develop efficiencies and find a way to more / most economical application.
Plenty of inert Nitrogen around in the atmosphere to capture and use too.
Giddyup on all that.
