DETAILED DESCRIPTION

[0014] A detailed description of one or more embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures.

[0015] Referring to Figures 1 - 3, a multi position sleeve valve 10 is illustrated. The valve 10 comprises a housing 12 and a sleeve 14 disposed therein. The housing 12 includes a port 16 extending from an inside diameter surface 18 to an outside diameter surface 20. In embodiments, ports 16 are located circumferentially about the housing 12. The housing 12 further comprises a shoulder 22, the purpose of which will become evident hereunder, and defines a sleeve movement area 24 that is sufficient in length to facilitate sleeve 14 movement from a housing port closed position (Figure 1) to a housing port open position (Figure 2) to a housing port closed position (Figure 3) in a single direction.

[0016] The sleeve 14 comprises a first portion 26 including a radially extending opening 28 therein and a second portion 30, the second portion 30 being releasably attached to the first portion 26 and releasably attached to the housing 12. The releasable attachment to the housing 12 comprises a releaser 32a and the releasable attachment to the first portion 26 comprises a releaser 32b each of which may in an embodiment be a shear screw or screws. The first portion 26 includes an inside diameter profile 34 to support engagement with a bottom hole assembly (BHA) 36 (See Figure 4) that shifts the sleeve 14, when desired. The second portion 30 presents, on an outer surface 38 thereof, a profile 40. Profile 40 is configured to abut shoulder 22 when the valve 10 is in the position illustrated in Figure 2. This position is reached at the beginning of a fracturing operation when the BHA 36 is used to move the sleeve 14 from the run-in closed position of Figure 1 to the open position of Figure 2. The shoulder will give a positive stop feedback to operators so that the uphole direction pull on the BHA 36 may be paused to allow for the fracturing operation to take place through the aligned opening 28 and port 16. In embodiments, there is also a snap ring 42 disposed in the housing 12 that snaps into grooves 44a and 44b in the sleeve 14 depending upon which position the sleeve 14 is in. One particular benefit of the valve disclosed herein is its tolerance to underdisplaced proppant in a fracturing operation. Underdisplacement, means that some of the proppant still remains in the port 16 rather than having been displaced completely out into the formation. The remaining proppant in/near the port 16 tends to cause frictional jamming of sleeves of the prior art. Sleeves of any kind of valve must be closed after the fracture operation to prepare the completion for production. The valve 10 does not suffer this indignity. This is in part due to the single direction actuation of the valve 10 from closed to open to closed again. All of the movement of the sleeve 14 is in a single direction, which may be uphole in an embodiment.

[0017] Once the fracturing operation is completed, the sleeve 14 is subjected to overpull from the BHA 36. The tensile force imparted to the sleeve 14 is initially reacted through the profile 40 against shoulder 22 but when the force grows to above a threshold force required to release releaser 32b, the releaser 32b releases the second portion 30 from the first portion 26. Upon release, the first portion 26 is drawn uphole and closes the ports 16 by misaligning the opening 28 with port 16. The second portion 30, however, stays in place, engaged with shoulder 22.

[0018] Referring to Figure 5, a borehole system 50 is illustrated. The system 50 comprises a borehole 52 in a subsurface formation 54. A string 56 is disposed within the borehole 52. A valve 10 as disclosed herein is disposed within or as a part of the string 56.

[0019] In use, the valve 10 is run into the borehole 52 to a target location with the sleeve 14 in a first closed position. When fracturing is desired, the BHA 36 is moved into engagement with the profile 34 and the sleeve 14 is pulled in an uphole direction to release releaser 32a, align the opening 28 and port 16, and engage the profile 40 of the second portion 30 with the shoulder 22 of the housing 12. This is the opened position. In this position proppant may be forcibly expelled through the port 16 into a surrounding formation 46. Before full displacement is achieved, the fracturing operation is halted, leaving proppant in the formation 46, in an annulus 48 and the port 16. The sleeve 14 is then subjected to overpull from an uphole location, like a surface location, through the BHA 36 until the releaser 32b releases. Once release is achieved, the first portion 26 is moved uphole to misalign the opening 28 and the port 16 to close the port 16 and prepare the valve for later production. This is the second closed position, The snap ring 42 will snap into groove 44b when the sleeve 14 is drawn fully uphole to retain the sleeve 14 in the closed position against unintended movement, until later opened for production. The sleeve 14 is configured to cycle between the opened position and the second closed position with reciprocal movement relative to the housing by using the profile 34.
