In this study, the authors present a method to monitor inter-well communication and drainage frac height through time based on unique geochemical fingerprint data collected from oils. This method does not require expensive instruments or interfere with production and its results were integrated with independent pressure gauge and well performance data to enable data-driven decisions on well spacing, well stacking and completion designs with different subsurface configurations. 

Their data showed that a three-targets scenario generated significantly more overlapped drainage vertically and vertical well communication than the two-targets scenario.  Geochemical data in the produced oils carry significant information to reveal subsurface fluid flow and well interaction through time. 

This presentation is from the 2022 SPE Hydraulic Fracturing Technology Conference and Exhibition.
