Patent ID: 8863850

Claim:
A method for stimulating a formation comprising: providing a tubular member in a wellbore of a subterranean formation, the tubular member having a bore formed therethrough capable of fluid flow and at least one burst disk, each burst disk comprising: a burstable disk positioned within a wall of the tubular member and in communication with the bore, the burstable disk blocking the flow of fluid therethrough when intact and having a rupture threshold; and a cap sealed within the wall, between the burstable disk and the wellbore, and spaced from the burstable disk for forming a chamber therebetween, the chamber containing a compressible fluid, having a chamber pressure and being pressure isolated from the wellbore, the cap preventing fluid outside the tubular accessing the chamber; running a treatment tubing having isolation elements thereon and a treatment port therebetween into the bore of the tubular member, forming an annular space between the treatment tubing and the tubular member; positioning the isolation elements in the annular space above and below at least one burst disk of the at least one burst disks; pumping fluid through the treatment tubing through the treatment port to the isolated interval for increasing the pressure in the isolated interval until the pressure reaches the rupture threshold; rupturing the burstable disk of the at least one burst disk in the isolated interval; moving the treatment tubing and isolation elements downhole from the ruptured burst disks for isolating the tubular bore therebelow; and flowing the treatment fluid through the annular space for exiting the ruptured burst disk for treating the subterranean formation.
