FRACTURING FLUID COMPOSITION AND METHOD UTILIZING SAME |
摘要 |
The present disclosure is directed to a composition and method of fracturing a formation penetrated by a well-bore. The composition and method comprises providing a fracturing fluid that is liquefied carbon dioxide (LCO2) with at least one friction reducing polymer that is a polysiloxane dissolved in the LCO2 at a concentration of about 0.001 to 1.0 weight percent, and a first at least one co-solvent, and optionally a second at least one co-solvent that has a closed cup flash point greater than the first at least one co-solvent, in order to enable dissolution of the polymer in order to effect friction reduction. |

1. A fracturing fluid composition, comprising: (i) liquid carbon dioxide (LCO2) in a quantity of at least 80 wt % of the fluid composition in combination with (ii) 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, and (iii) at least one co-solvent in an amount of 1-19 wt % of the fracturing fluid composition, wherein said friction reducing polymer is soluble in the at least one co-solvent and LCO2 mixture. |
