New polymer composition for oil and gas recovery |
| abstract |
A composition for preparing an injection fluid in oil and gas recovery comprising an inverse emulsion of a water-soluble polymer A comprising cationic monomer units, and solid particles of a water-soluble polymer B comprising cationic monomer units, and wherein water-soluble polymer A comprises between 10 and 40 mol% of a cationic monomer units based on the total amount of monomer units; and wherein the cationicity in mol% of polymer A is superior or equal to the cationicity in mol% of polymer B. Method of treating a portion of subterranean formation comprising providing said composition, preparing an injection fluid with at least said composition, introducing the injection fluid into portion of the subterranean formation. The composition is particularly useful to prepare fracturing fluid in fracturing operations. |
