Abstract:
The invention relates to a multi-stage hydraulic fracturing tool and system for controllably exposing selected locations along a wellbore to a pressurized fluid. The system comprises an elongated casing (for disposal within the wellbore) defining an internal borehole extending longitudinally, and having one or more ports; an actuation member configured for travelling down the borehole and includes a wedged portion and a groove having a first length in the longitudinal direction, formed at least partially circumferentially around an outer surface of the actuation member, a sliding sleeve member having an aperture for receiving the actuation member, and one or more inward-facing protrusions having a length less than or equal to the first length, connected to the sliding sleeve member and at least initially protruding radially into the aperture.

Claim (Index 6):
The system of  claim 1 , further comprising:\n a second sliding sleeve member for disposal within the borehole uphole of the first sliding sleeve member, the second sliding sleeve member having a second aperture for receiving the actuation member therein, the second sliding sleeve member initially covering a second port extending through the casing and configured, upon application of a second predetermined amount of force applied in the longitudinal direction, to move downhole in the longitudinal direction, thereby uncovering the second port; and one or more second inward-facing protrusions connected to the second sliding sleeve member, the one or more second inward-facing protrusions biased to protrude radially into the second aperture, the one or more second inward-facing protrusions movable radially outward by the wedged portion of the actuation member when the actuation member moves downhole, or the actuation member being radially inwardly compressed by action of the one or more second inward-facing protrusions on the wedge when the actuation member moves downhole, or both, the one or more second inward-facing protrusions having a third length in the longitudinal direction, the third length being greater than the first length, the one or more second inward-facing protrusions and the groove thereby configured to refrain from moving radially toward one another during passage of the actuation member between the one or more second inward-facing protrusions, thereby allowing passage of the actuation member past the second sliding sleeve member without imparting the second predetermined amount of force thereto.
