Claim:
1. A fracturing fluid composition, comprising: (i) liquid carbon dioxide (LCO 2 ) in a quantity of at least 80 wt % of the fluid composition in combination with (ii) at least one friction-reducing polydimethylsiloxane polymer, having a molecular weight greater than 597,000 g/mol, and a kinematic viscosity greater than 20,000,000 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 LCO 2 mixture.
