System and Method for Detecting Screen-out using a Fracturing Valve for Mitigation |
| 摘要 |
A system and method for detecting screen-out using a fracturing valve for mitigation is disclosed herein. The fracture method can comprise fracturing a well using a fracturing valve, while a downhole pressure is less than a predetermined threshold. The method can also comprise actuating by automated process the fracturing valve from a fracturing position to a nonfracturing position upon detecting by a pressure sensor in the wellbore that the downhole pressure has reached said predetermined threshold. |

1. A method of detecting screen out using a fracturing valve comprising
fracturing a well using a fracturing valve, while a downhole pressure is less than a predetermined threshold; and actuating by automated process said fracturing valve from a fracturing position to a non-fracturing position upon detecting by a pressure sensor in said wellbore that said downhole pressure has reached said predetermined threshold. |
