As unconventional resources mature toward full field developments, parent-child interactions may impact the ultimate recovery of the production units. This session presents case studies from various operators highlighting their approaches toward identifying the potential for fracture driven interactions, diagnostics techniques which can be used to characterize the created fracture geometries during infill completion operations, mathematical methods used to optimize the infill completions and practical methods to minimize fracture driven interactions. Parent-child interactions are also critical in the development of geothermal and carbon capture and storage reservoirs. For this reason, papers on these emerging developments are included in the session.
