Abstract:
A method, system, and apparatus required for creating a mixture of dry proppant and liquid carbon dioxide (LCO 2 ) for fracturing oil and gas formations is presented. The operation includes making a mixture of dry proppant and liquid carbon dioxide (LCO 2 ) for use in a fracturing operation by supplying dry proppant that is pressurized to between 75 and 600 psia with a gas; further supplying a stream of sub-cooled LCO 2  having a pressure substantially equal to that of the pressurized dry proppant; and adding dry, pressurized proppant to the stream of sub-cooled LCO 2 , thereby forming a mixed LCO 2  and proppant fracturing slurry.

Claim (Index 11):
The apparatus of  claim 10 , wherein said fracturing fluid is delivered to at least one high pressure pump to further increase the pressure of the fracturing fluid prior to supply to an injection well to carry out the fracturing operation.
