摘要
A method, system, and apparatus required for creating a mixture of dry proppant and liquid carbon dioxide (LCO2) for fracturing oil and gas formations is presented. The operation includes making a mixture of dry proppant and liquid carbon dioxide (LCO2) 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 LCO2 having a pressure substantially equal to that of the pressurized dry proppant; and adding dry, pressurized proppant to the stream of sub-cooled LCO2, thereby forming a mixed LCO2 and proppant fracturing slurry.
