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 5):
A method of setting a hydraulic open hole packer comprising:\n a. injecting fluid into a mandrel of the packer; b. actuating a piston of the packer from an unset to a set position by pressure from the injected fluid; c. setting a ratchet of the packer by pressure from the injection fluid to to maintain the packer in the set position once actuated, wherein both a setting stroke for actuating the piston and a setting stroke for setting the ratchet profile are combined into one stroke.
