Systems and methods for managing flowback fluids produced during a flowback process in a well are provided. The system includes a well formed in a target zone in a hydrocarbon reservoir, where the well also extends to a disposal zone. The system also includes a check valve or zonal isolation systems. The method includes selecting a disposal zone, directing the formation of a well extending through a target zone and a disposal zone, transporting the flowback fluid from the target zone to the disposal zone during the flowback process, and selectively plugging the well near the disposal zone to prevent migration of the flowback fluid.
