Abstract:
A method is provided for multistage isolation and fluid treatment of a borehole, in which a first frac valve tool and a second frac valve tool are provided, a first packer is mounted downstream from the first frac valve tool, a second packer is mounted between the first frac valve tool and the second frac valve tool, a third packer is mounted upstream from the second frac valve tool, at least one of the first, second and third packers being a hydraulic set packer having a single packing element, the first frac valve tool being moveable between a closed and an open position, the second frac valve tool moveable between a closed and an open position; running the liner into a wellbore; hydraulically setting the single element packers; conveying means for moving the first frac valve tool to the open position; and forcing stimulation fluid out through the first frac sleeve tool.

Claim (Index 1):
A method for multistage isolation and fluid treatment of a borehole, the method comprising:\n a. providing an apparatus for wellbore treatment including a liner, a first frac valve tool, a second frac valve tool upstream from the first frac valve tool along the liner, a first packer operable to seal about the liner and mounted on the liner downstream from the first frac valve tool, a second packer operable to seal about the liner and mounted on the liner between the first frac valve tool and the second frac valve tool, a third packer operable to seal about the liner and mounted on the liner upstream from the second frac valve tool, at least one of the first, second and third packers being a hydraulic set packer and at least one of the first, second and third packers having a single packing element, the first frac valve tool being moveable between a closed position and an open position permitting fluid flow through the first frac valve tool, the second frac valve tool moveable between a closed position and an open position permitting fluid flow through the second frac valve tool; b. running the liner into a wellbore in a desired position for treating the wellbore; c. hydraulically setting the single element packers; d. conveying means for moving the first frac valve tool to the open position; and e. forcing stimulation fluid out through the first frac sleeve tool.
