COPOLYMER AND Aqueous Preparation Containing the Copolymer. |
| abstract |
A hydrophobe associative composition of an ethylenically unsaturated, water-soluble monomer such as acrylamide and an ethylenically unsaturated amphiphilic monomer such as dodecyl poly(oxyethylene)10 methacrylate which is particularly effective for increasing the viscosity of brines or other aqueous media contaning salts or other electrolytes. Such copolymers are therefor useful in mobility control fluids and fracturing fluids for enhanced oil recovery and as drag reduction agents. |
