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 1):
A system for controllably exposing selected locations along a wellbore to a pressurized fluid, the wellbore including an elongated casing disposed therein, the casing defining an internal borehole extending longitudinally with the wellbore, the casing having one or more ports extending through the casing, the system comprising:\n an actuation member configured for travelling down the borehole in a longitudinal direction, the actuation member including a wedged portion and a groove formed at least partially circumferentially around an outer surface of the actuation member, the groove having a first length in the longitudinal direction; a sliding sleeve member for disposal within the borehole and having an aperture for receiving the actuation member therein, the sliding sleeve member configured to initially cover the port, and further configured to move downhole in response to force in the longitudinal direction to uncover the port; and one or more inward-facing protrusions connected to the sliding sleeve member, the protrusions at least initially protruding radially into the aperture, the protrusions having a second length in the longitudinal direction, the second length being less than or equal to the first length, one or both of the protrusions and the groove configured, upon alignment of the protrusions and the groove, to move radially toward the other due to a biasing force so that the protrusions are received within the groove, whereupon the predetermined amount of force is transferred from the actuation member to the sleeve member, wherein one or both of the actuation member and the sliding sleeve have a deformation region, wherein the deformation region of the sliding sleeve has the one or more inward facing protrusions; wherein the biasing force is generated by one or both of: resilient radial outward deformation of the deformation region of the sliding sleeve member, and resilient radial inward deformation of the actuation member, said resilient radial outward and inward deformation occurring in response to action of the wedged portion on the protrusions during downhole motion of the actuation member past the protrusions.
