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 involves performing an enhanced oil recovery (EOR) operation. The method includes injecting a gas stream into a well via a first channel. The method also includes injecting enhanced oil recovery chemicals (EROCs) into the well via a second channel. The second channel is different from the first channel. An end of the first channel and an end of the second channel are positioned to facilitate static mixing of the gas stream with the EROCs to form an enriched gas stream in a subsurface region. The enriched gas stream facilitates the EOR operation.
