Abstract

Official abstract text for this publication.

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 carbon dioxide (CO2) with at least one friction reducing polymer that is a fluoropolymer dissolved in the CO2 at a concentration of about 0.001 to 0.4 weight percent.

First claim

Opening claim text (preview).

We claim: 1. A fracturing fluid composition, comprising: (i) carbon dioxide (CO 2 ) in combination with (ii) a friction-reducing polymer in an amount of at least 0.001 to less than 0.1 weight percent of the fluid composition, wherein the friction reducing polymer has a weight average molecular weight greater than 100,000 grams per mole and comprising of at least fluoroacrylate monomers, wherein said friction reducing polymer is at least partially soluble in the CO 2 . 2. A fracturing fluid composition of claim 1 , wherein the friction reducing polymer reduces friction of said fracturing fluid at least 10% lower than that of pure carbon dioxide. 3. A fracturing fluid composition of claim 1 , wherein the friction reducing polymer is a copolymer where one of the said monomers is styrene. 4. A fracturing fluid composition of claim 1 , wherein the friction reducing polymer is a copolymer where one of the said monomers is vinyl acetate.
