Diverting agents for well stimulation |
| abstract |
The present application provides expandable chemical diverting agents, such as flexible polyurethanes and swellable hydrogels, or chemical precursors thereof. Methods of using these expandable diverting agents for treating a subterranean formation are also provided. An example of subterranean formation treatment process described in the present application is wellbore stimulation, such as hydraulic fracturing or matrix acid treatment. |
