There is provided a fluid communication-interference body, such as a frac ball, for deployment downhole within a wellbore for effecting interference to fluid communication between the wellbore and the subterranean formation. The body may include a shall and an inner core. The shell includes shell material which may include metal-comprising material, such as titanium. The core includes core material. The core material may include composite material such as microspheres distributed within a polymer material-comprising matrix.

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.

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.

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. The hydraulic fluid supply source is configured to supply hydraulic fluid to the first chamber in response to an expansion in volume of the first chamber that is effected by the extension of the protrusible member.
