Apparatus, systems and methods for completion operations

A method for treating a wellbore completed with a completion string having a plurality of sleeve valves therealong, each sleeve valve having a sleeve housing and an axially shiftable sleeve, each sleeve having an annular profile intermediate the sleeve, comprising:

• selecting a target sleeve valve for treatment, the target sleeve valve being closed;
• running a shifting tool downhole in a run-in-hole (RIH) mode by actuating a mandrel axially relative to a housing portion, the housing portion supporting one or more radially pivotable arms, each arm bearing a sleeve engaging member, and a drag block connected to the housing portion and adapted for resisting axial movement of the housing portion in the wellbore, the one or more pivotable arms shifted to a radially inward position and positioning the shifting tool downhole of the selected sleeve valve;
• shifting the shifting tool uphole to a pull-to-locate (PTL) mode, the one or more pivotable arms shifted to a radially outward biased position, locating the annular profile of the sleeve of the target sleeve valve and engaging the sleeve engaging elements therewith, and shifting the target sleeve valve uphole to an open position;
• shifting the shifting tool downhole to a SET-FRAC mode, the housing portion actuated to position one or more sealing elements of the shifting tool downhole of the target sleeve valve for treating the wellbore;
• shifting the shifting tool uphole to a pull-to-relocate (PTR) mode, the one or more pivotable arms shifted to the radially outward biased position, and pulling the shifting tool uphole for locating the annular profile of the sleeve of the target sleeve valve and engaging the sleeve engaging elements therewith;
• shifting the shifting tool downhole to a SOFT-SET-CLOSE mode, the one or more sealing elements partially activated and the sleeve-engaging elements locked in engagement with the target sleeve;
• applying fluid pressure in an annulus between the shifting tool and the completion string to apply a downhole force on the shifting tool to shift the target sleeve valve to a closed position;
• and
• shifting the tool to a pull-out-of-hole (POOH), the one or more arms in the radially inward collapsed position for pulling the shifting tool out of hole to a subsequent uphole sleeve valve.

A treatment system comprising:

• a completion string having a plurality of sleeve valves therealong, each sleeve valve having a sleeve housing having one or more ports and a bore fit with an axially shiftable sleeve, each sleeve having an annular profile formed intermediate the sleeve;
• and
• a shifting tool having:
• a first housing portion having a first shifting mechanism;
• a second housing portion having a second shifting mechanism, the second housing portion telescopically connected to the first housing portion and adapted for axially telescoping between a collapsed position and an extended position;
• a drag block connected to the second housing portion and adapted for resisting axial movement the second housing portion in the wellbore;
• a mandrel having a first shifting member adapted to cooperate with the first shifting mechanism, a second shifting member adapted to selectably cooperate with the second shifting mechanism, a retaining member, one or more sealing elements, and a cone;
• and
• one or more sleeve engagement members supported on one or more pivotable arms, the one or more arms supported by the first housing portion, each of the one or more pivotable arms being radially actuable by the retaining member between at least a radially outward position and a radially inward position.
