Abstract
The present invention relates to a process of supplying a proppant-containing fracturing fluid to a wellhead, wherein the proppant-containing fracturing fluid can be continuously supplied during the fracture treatment.
Claims8
1-14. (canceled)
A process of continuously supplying a proppant-containing fracturing fluid utilized in a fracturing operation, comprising:
- (a) pressurizing a stream of liquid CO2, and routing it through a first conduit;
- (b) continuously providing an additive slurry stream of proppant and at least one co-solvent;
- and
- (c) pressurizing the slurry stream of step (b) and adding it to the pressurized stream of liquid CO2 thereby forming a proppant-containing fracture fluid which is continuously supplied to the wellhead.
1 more element
A fracturing apparatus, utilized in a continuous fracturing operation, comprising:
- (a) at least one tank for storing and supplying a liquid CO2 through a main conduit to a high pressure fracturing pump;
- and
- (b) second conduit for supplying a slurry of proppant and at least one co-solvent through at least one second high pressure pump, wherein the slurry is injected into the main conduit downstream of the at least one first high pressure pump.
