Closeable sleeve assembly and method of use

A method for locating a shifting tool in a sleeve, the sleeve being axially moveable within a housing for shifting the sleeve axially therein between uphole and downhole positions, comprising:

• running the shifting tool downhole, through a bore of the sleeve, to below a downhole end of the sleeve;
• pulling the shifting tool uphole, the shifting tool being guided uphole past a downhole housing ramp and into the downhole end of the sleeve by a downhole sleeve ramp formed thereon;
• continuing to pull the shifting tool uphole to engage in the sleeve
• axially moving the locating shifting tool and, sleeve engaged therewith, between the uphole and downhole positions, wherein uphole and downhole stops in an annulus between the sleeve and the housing engage uphole and downhole shoulders therein, the annular stops and annular shoulders acting between the sleeve and the housing to delimit the axial movement of the sleeve;
• pulling the shifting tool uphole out of the bore of the sleeve by disengaging the shifting tool from the sleeve;
• and
• pulling the shifting tool uphole to move from an uphole end of the sleeve by an uphole sleeve ramp and into a bore in the housing guided by an uphole housing ramp formed at an uphole end of the housing.

A sleeve assembly comprising:

• a tubular sleeve housing having a housing bore formed therethrough, the housing having
• one or more ports formed therethrough;
• and
• a shifting profile formed in an inner surface of the housing bore, the shifting profile having an uphole shoulder and a downhole shoulder;
• and
• an axially shiftable tubular sleeve adapted for axial shifting movement by a shifting tool guided therethrough, the sleeve housed within the housing bore and forming a sealed sleeve annulus therebetween, the sleeve having
• a sleeve bore formed therethrough;
• annular uphole and downhole stops formed on an exterior of the sleeve and extending into the sleeve annulus for engaging the uphole and downhole shoulders of the shifting profile for delimiting the axial movement of the sleeve when the shifting tool shifts the sleeve between a closed position, wherein the sleeve blocks the ports, and an open position, wherein the sleeve is shifted axially away from the ports;
• and
• opposing housing and sleeve ramps formed on opposing uphole ends of the sleeve and housing bore and on opposing downhole ends of the sleeve and housing bore, the opposing ramps guiding the shifting tool into and out of the housing bore and the sleeve bore.
