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 7):
The system of  claim 6 , further comprising a second actuation member configured for travelling down the borehole in the longitudinal direction, the second actuation member including a second wedged portion and a second groove formed at least partially circumferentially around a second outer face of the second actuation member, the second groove having a fourth length in the longitudinal direction, the fourth length being greater than or equal to the third length of the one or more second inward-facing protrusions, one or both of the one or more second inward-facing protrusions and the second groove configured, upon alignment of the one or more second inward-facing protrusions and the second groove, to move radially toward the other due to a second biasing force so that the one or more second inward-facing protrusions are received within the second groove, whereupon a second radially oriented face of the second groove engages respective radially oriented faces of each of the one or more second inward-facing protrusions to transfer the second predetermined amount of force from the second actuation member to the second sleeve member,\n wherein the second biasing force is generated by one or both of: resilient radial outward deformation of a second deformation region of the second sliding sleeve member, the second deformation region including the one or more second inward-facing protrusions; and resilient radial inward deformation of the second actuation member, said resilient radial outward and inward deformation occurring in response to action of the second wedged portion on the one or more second inward-facing protrusions during downhole motion of the second actuation member past the one or more second inward-facing protrusions.
