1. A method of influencing behavior of a subterranean formation, comprising:

  • (a) injecting a pressurized fluid comprising a gas into at least two injection wells to pressurize pre-existing fractures of the subterranean formation adjacent to the at least two injection wells, the at least two injection wells being spatially proximate to a target well of the subterranean formation, and increase a pressure of the at least two injection wells; and

    (b) maintaining, for a suitable injected fluid dwell time, the pressurized fluid in the pressurized pre-existing fractures while a carrier liquid is introduced into the target well to induce hydraulic fracturing in the target well,wherein the target well and the injection wells are not all collinear, andwherein the pressurized fluid is maintained at an injection pressure below a fracture gradient of the subterranean formation during the duration of steps (a) and (b), and wherein the carrier liquid is injected into the target well at a sufficient pressure above the fracture gradient to fracture the subterranean formation.
