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 24):
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 a first actuation member configured for travelling down the borehole; a first sliding sleeve member for disposal within the borehole, the first sliding sleeve member configured to initially cover one of the one or more ports, the first sliding sleeve member further configured to engage with the first actuation member and to move downhole to uncover said one of the one or more ports in response to said engagement, the first sliding sleeve having an aperture having a first diameter for receiving the first actuation member; and a second actuation member configured for travelling down the borehole, the second actuation member having a second diameter smaller than the first diameter to allow the second actuation member to travel through the aperture of the first sliding sleeve member without engagement.
