Abstract A sliding sleeve assembly for opening the setting port of a hydraulically set well packer which may be reversibly positioned for actuation in either an upwardly or downwardly direction. A shearable plug initially blocking the setting port and positioned in an elongate recess in the packer which extends equal distances on either side of the setting port with a shoulder at each end of the recess and a sliding sleeve telescopically positioned in the recess and in engagement with the plug whereby when the sleeve is longitudinally moved the plug is sheared. One end of the sleeve extending from the axis of the port a distance equal to one-half the length of the recess whereby the one end will engage one of the shoulders at the end of the recess and said sleeve may be positioned in the recess for actuation in either the upwardly or downwardly direction. The sleeve including an actuation shoulder positioned on one side of the plug when the sleeve is in engagement with the plug and including a wedge-shaped shoulder on the second side of the plug protecting the plug but allowing passage of a setting tool. The shoulders at the ends of the recess being tapered for retracting a setting tool after the sleeve is shifted in the recess.
In a hydraulically set well packer having a setting port in communication with an internal passageway the improvement in a sliding sleeve assembly for opening the port comprising, means initially blocking the setting port, said internal passageway including an elongate recess extending equidistance on either side of the setting port, a shoulder at each end of the recess, a sliding sleeve telescopically positioned in the recess and in engagement with the initially blocking means whereby when the sleeve is longitudinally moved the initially blocking means is opened, said sleeve including an actuating shoulder facing in one direction for engagement by a shifting tool for moving the sleeve in the second direction, one end of the sleeve extending from the axis of the port a distance equal to one-half the length of recess whereby said end will engage one of the shoulders at the end of the recess when the sleeve is in engagement with the initially blocking means and said sleeve may be positioned in the recess for actuation of the sleeve in either the first or second direction.
