CL Sliding Sleeve / Circulating Sleeve

CL Sliding Sleeve / Circulating Sleeve  

Model CL Sliding Sleeve or Circulating Sleeve is a downhole flow control device mounted in the production tubing. It provides a way to establish or shut off communication between the tubing and the annulus. It features a comparable Baker “F” profile in the top sub and sealing bore in the bottom sub. Any number of sleeves may be run in a tubing string and any or all of them may be opened or closed with Model D-2 Shifting Tool. The CL inner sleeve functions as UP to OPEN and DOWN to CLOSE.

APPLICATIONS

• Circulating inhibitors or methanol
• Allow multiple zones to produce up one tubing string
• Selective Testing or Stimulation of individual zones
• Circulating to kill the well
• Gas lifting the well
• Landing a blanking plug in the profile to shut in the well, test the tubing, or test the sleeve itself

FEATURES

• Comparable Baker “F” Profile
• Bonded rubber on inner sleeve
• Internal sealing bore in both top and bottom sub for maximum sealing capacities
• Model D-2 shifting tool is used to OPEN (shifting UP) or CLOSE (shifting DOWN) the inner sleeve
• Communication Ports can be closed without leaving any obstruction in the tubing once the shifting operation is complete
