  • Publication number: 20160265310
    Abstract: There is provided a flow control apparatus including a housing, a port, a flow control member, a sensor, and a trigger. The housing includes a housing passage. The port extends through the housing. The flow control member includes a fluid responsive surface, and is configured for displacement, relative to the port, such that fluid communication is effected between the port and the housing passage. The sensor is coupled to the housing for sensing an actuating signal. The trigger is configured for effecting fluid communication between the housing passage and the fluid responsive surface, in response to the sensing of an actuating signal by the sensor, for effecting displacement of the flow control member.

  • Publication number: 20160215590
    Abstract: There is provided a method of stimulating a formation within a wellbore that is lined with a wellbore string, the wellbore string including a port and a flow control member, wherein the flow control member is displaceable relative to the port for effecting opening and closing of the port. The port is opened by displacing the flow control member in response to an applied pressure differential across a sealing interface. The port is closed by displacing the flow control member with hydraulic hold down buttons prior to removing the sealing interface and effecting pressure equalization.

  • Publication number: 20160090803
    Abstract: There is provided a locator configured for coupling to a workstring for locating a wellbore feature, The locator includes a protrusible member, a chamber, a hydraulic fluid supplying passage, and a hydraulic fluid supply source. The protrusible member is moveable, relative to the workstring, and biased for disposition, relative to the workstring, in an extended position. In the extended position, the protrusible member is engageable with the wellbore feature. The first chamber is disposed in fluid pressure communication with the protrusible member, and has a volume configured to change correspondingly with a change in position of the protrusible member such that expansion of the first chamber corresponds with an extension of the protrusible member and such that contraction of the first chamber corresponds with a retraction of the protrusible member. The hydraulic fluid supply source is fluidly coupled to the first chamber via the hydraulic fluid supplying passage.
