Operation
The B Shifting Tool is used to open or close all Sliding Sleeve and is run with a standard string of wireline tools. The Keys are shaped so that when traveling in one direction the sloped surface at one end will allow them to pass through the Sliding Sleeve. In the opposite direction, the square shoulder near the center of the Keys will engage a corresponding shoulder inside the Closing Sleeve. Further movement of the B Shifting Tool will move the Closing Sleeve to full Open, Closed or equalizing position depending upon the operation being performed. When either open or closed position is reached, Standard Keys are release by means of an inclined shoulder inside the Sliding Sleeve which forces the Keys inward and disengages them from the Closing Sleeve. The fact that the Shear Pin does not shear is a positive indication that the Closing Sleeve has been fully positioned.
