VISCOSIFIER FOR ENHANCED OIL RECOVERY |
摘要 |
Various embodiments disclosed relate to methods, compositions, and systems for enhanced oil recovery including a viscosifier polymer. In various embodiments, the present invention provides a method of enhanced oil recovery that can include obtaining or providing a composition that includes a viscosifier polymer. The viscosifier polymer includes an ethylene repeating unit including a -C(O)NH2 group and an ethylene repeating unit including an - S(O)2OR1 group, where the repeating units are in block, alternate, or random configuration. At each occurrence R1 can be independently selected from the group consisting of -H and a counterion. The method can include placing the composition in a subterranean formation downhole via an injection wellbore. The method can also include extracting material comprising petroleum from the subterranean formation downhole via a production wellbore. |
