Past simulation work demonstrates how depletion and fracture communication between parent and child wells can lead to child well underperformance. However, as completion designs evolve and more state-of-the-art horizontal wells are completed in these basins, it is necessary to revisit this analysis and adjust and add to the previous body of work.  In this study, parent-child well pairs for wells completed within the last seven years in nine different unconventional basins are identified using a Python code applied to Enverus public data. The study confirms that child well performance increases with spacing and decreases with infill timing. These assessments can help operators manage child well underperformance and can help them understand the effects of differing well spacing and infill timing on child well performance in US unconventional basins.
