Method of making a fracturing fluid composition and utilization thereof |
| 摘要 |
The present disclosure is directed to a method of making a fracturing fluid and system of fracturing a formation penetrated by a well-bore. The method includes providing a fracturing fluid that is liquefied carbon dioxide (LCO2) and a co-solvent in a quantity of 1-19 wt %, and at least one friction-reducing polymer in a quantity of 0.001-1.0 wt % of the fracturing fluid composition, wherein the friction-reducing polymer is initially disposed in an emulsion, and is at least partially soluble in the co-solvent and LCO2 mixture. |

1. A method of making a fracturing fluid, comprising: (i) providing liquid carbon dioxide (LCO2) in a quantity of at least 80 wt % of the fracturing fluid from a storage tank and routing it through a fracturing pump disposed in a main conduit; (ii) adding a co-solvent in a quantity of 1-19 wt % of the fracturing fluid composition downstream of the fracturing pump; and (iii) adding at least one friction-reducing polymer having a kinematic viscosity greater than 10,000,000 cSt in a quantity of 0.001-1.0 wt % of the fracturing fluid composition downstream of the fracturing pump, wherein said friction-reducing polymer is initially disposed in an emulsion, and is at least partially soluble in the co-solvent and LCO2 mixture. |
