Flowing Fracturing Fluids to Subterranean Zones |
| 摘要 |
Implementations provide flowing of fracturing fluids to subterranean zones. Actions can include In some examples, a method includes actions of flowing a mixture of a first quantity of acid and a second quantity of a polymer diverting agent (PDA) having a viscosity that changes with acid concentration to a first portion of a subterranean zone, wherein the first quantity decreases as the acid reacts with metal in the first portion, and wherein the viscosity of the PDA increases as the first quantity decreases to form a PDA gel and flowing a third quantity of acid through the subterranean zone, wherein the PDA gel diverts the acid from the first portion to a second portion of the subterranean zone. |

1. A method comprising:
flowing a mixture of a first quantity of acid and a second quantity of a polymer diverting agent (PDA) having a viscosity that changes with acid concentration to a first portion of a subterranean zone, wherein the first quantity decreases as the acid reacts with metal in the first portion, and wherein the viscosity of the PDA increases as the first quantity decreases to form a PDA gel; and flowing a third quantity of acid through the subterranean zone, wherein the PDA gel diverts the acid from the first portion to a second portion of the subterranean zone. |
