Infill well completion technologies, including far-field diverter, near-wellbore diverter, and real-time pressure monitoring, have been used to mitigate negative FDI (Fracture Driven Interactions) between parent and child wells in the Bakken, Wolfcamp, and Barnett formations. Negative FDI’s can cause decreased production in parent wells, as well as other negative effects such as wellbore sanding, casing damage, and reduced production performance from infill wells. The main goal for all the pads in this study was to maintain production of the parent wells, decrease the frequency and severity of frac hits to parent wells, and avoid wellbore sanding, which would require wellbore cleanouts.

Real-time pressure monitoring allowed acquisition of parent well pressure data to identify pressure communication or lack of communication and implement mitigation and contingency procedures, as necessary. Real-time pressure monitoring was also used to optimize and validate the performance of far-field diverters. Applying the infill well completion technologies consistently on multiple wells helped mitigate frac hits, as evidenced by real-time pressure monitoring. Overall, about 85% of the parent wells protected showed positive uplift in production, maintained for at least 6 months, and fewer, costly wellbore cleanouts. In summary, fracture diagnostics, along with production data evaluation, can be highly beneficial in understanding the role of production depletion, completion design, and well spacing in fracture-driven interactions.
