The time at which gas pressure drops below its initial value everywhere in the rock between hydrofractures is called its interference time.

Diverting more gas from the domestic energy market would exert even more upward pressure on fuel gas prices, and with gas prices on the rise you're going to start setting more pushback from consumers and less support for fracking (short for hydrofracturing), the shale drilling method that has been causing so many problems in local communities.
