1. A method for determining propped fracture dimensions for a parent well, comprising:
hydraulic fracturing a stage of a child well to form a child well fracture extending into a surrounding formation;
during the hydraulic fracturing of the stage of the child well, measuring, via a parent well, data that are indicative of a formation of a hydraulic connection between the child well and the parent well via an interaction between a wetted front of the child well fracture and a propped region of a corresponding parent well fracture;
measuring at least one of time to first response (TFR) data or volume to first response (VFR) data corresponding to the formation of the hydraulic connection between the child well and the parent well;
estimating a dimension of the child well fracture when the hydraulic connection was formed using the at least one of the TFR data or the VFR data, in combination with at least one fracture growth profile; and
estimating a propped fracture dimension of the parent well fracture based on the estimated dimension of the child well fracture and a distance between the child well and the parent well at the corresponding stage.
