Can we use pressurised CO2 to do fracking?

NISKAYUNA, New York, April 7 (Reuters) - Carbon dioxide, used for years to force crude oil out of old wells, likely will not replace water in fracking ... 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. read more

Yes, you can use carbon dioxide and other gasses, such as nitrogen, for hydraulic fracturing operations. This is known as water-less fracking (or dry fracking). It has one major downfall however and that is the cost compared with other methods. read more

Adding CO2 instead of water to the cocktail used in fracking, could boost oil and gas extraction and help fight global warming at the same time, scientists said Tuesday.

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. read more

We don't always use fresh water for drilling and fracking but, as Ryan said, the water issue is mostly propaganda. Fracking hasn't depleted the Ogallala, tens of thousands of irrigation pumps have. We have salt water gels so, we can suspend sand in salt water and use it in fracks. read more
