A process for fracturing a selected region of a formation including: introducing a supply of fracturing fluid to the region of the formation until a first threshold is reached, adjusting the flow of the fracturing fluid to the region of the formation to reach a second threshold, adjusting the flow of the fracturing fluid to the region of the formation to reach a third threshold and ceasing flow of the fracturing fluid to region of the formation, the fracturing fluid being a non-participating gas and including a proppant in at least one of the stages of flow of the fracturing fluid.

Well product recovery process

A well may intersect a mineral bearing stratum. A fracturing fluid in the nature of a non-participating gas may be injected into the stratum at high rates of flow, to yield a high down hole pressure, and a time v. pressure pulse extending over a period of time. A second pulse may follow the first pulse in relatively quick succession. There may be pauses, or period of relative relaxation between the pulses.
