Innovative approach to understanding fracture interactions
Parent-child well interactions can lead to compromised frac completions and significantly impact production. While there are several techniques for evaluating pressure communication between active completions and existing wells during or after fracturing treatments (frac hits), greater value comes from the ability to predict and prevent or mitigate these fracture interactions.
D2F is leading the way in predicting frac hits from parent-child interactions The Depleted Fracture Identification (DFI) process identifies where infill wells have crossed existing fractures and, predicts potential frac hits from new completions, and provides actionable recommendations using the same drilling data that creates our OmniLog® lateral profile. The process precisely locates conductive channels between wells through identification of areas of localized depletion. These areas are most often associated with fractures connected to a parent well. The DFI process can therefore be used for frac-hit mitigation, to reduce completion costs, and to understand the fracture growth that occurred in a parent well.
