Abstract:
1. A method of fracturing a formation through a wellbore, comprising the steps of: injecting a gas into the formation at a rate and pressure sufficient to fracture the formation; adding a solid particulate to the gas whereby the solid particulate flows with the gas through the wellbore and into fractures in the formation; ceasing the addition of solid particulate while continuing the injection of gas to place the solid particulate into the fractures; and ceasing of the injection of gas thereby allowing the fractures to close on the solid particulate; where the solid particulate is injected at a concentration ranging from 800 to 1200 kilograms of the solid particulate per cubic meter of dry gas at surface temperature and pressure, and 40 to 60 kilograms of the solid particulate per cubic meter of gas at downhole temperature and pressure.
