Irradiation produced AMPS/Am copolymers in thickened acid compositions. |
| 摘要 |
<p>Water-soluble thickened acid compositions suitable for matrix or fracture acidizing are provided comprising water, an acid, and an acid thickening amount of a copolymer of sodium 2-acrylamido-2-methylpropane sulfonate and acrylamide produced by irradiation. These compositions are useful without a crosslinking agent. They are also suitable for mud acidizing.</p> |
