Abstract: A method for controlling the growth of a hydraulic fracture using a stress shadow generated during a hydraulic fracturing operation includes selecting a stage pair including a first stage and a second stage for which hydraulic fractures are to be generated via a hydraulic fracturing operation. The method also includes hydraulic fracturing the first stage to generate a corresponding first hydraulic fracture and controlling a magnitude of a stress shadow originating from the first hydraulic fracture by varying at least one parameter of the hydraulic fracturing operation, where the stress shadow is controlled so as to provide a second hydraulic fracture of a target fracture shape for the second stage. The method further includes hydraulic fracturing the second stage to generate the second hydraulic fracture with the target fracture shape.

Abstract: A method for adjusting the treatment schedule for a hydraulic fracturing operation corresponding to a hydrocarbon well to limit one or more pumping parameters (e.g., the pump time, pump volume, and/or pump rate) includes analyzing fracture diagnostic data and/or fracture model data to estimate the pumping parameter(s) at which the maximum number of hydraulic fractures will approximate a target fracture dimension during the hydraulic fracturing operation. The method also includes adjusting the treatment schedule for the hydraulic fracturing operation based on the estimated pumping parameter(s) and then hydraulic fracturing the hydrocarbon well according to the adjusted treatment schedule.
