Zusammenfassung:A system and method to predict or detect screen outs by measuring pressure conditions in the well in real-time, and that conducts mitigation of the condition. Pressure responses of the well are detected during a fracture operation. The system processes the pressure responses by removing the effects of non-screen out related factors. A mathematical model is applied to the pressure responses to detect or predict the screen out. In response to the screen out detection or prediction, corrective action may be initiated.
