The CM™ series sliding sleeves are high performance, equalizing sliding sleeves which allow communication between the tubing and annulus for circulation or selective-zone production. When desired, the sleeve can be shifted open or closed using standard wireline methods and a B™ type shifting tool. The tool is designed such that any lock profile and compatible seal bores can be specified to accept a wide range of wireline locks, and accessories. The sleeve is available in CMD™ downshift-to-open or CMU™ upshift-to-open versions.

Application

  • Seal bore packers

Features and Benefits

  • A specially designed diffuser ring made of high-strength thermoplastic is critically spaced between the flow ports and the upper packing unit. This prevents damage to the upper packing unit during shifting by controlling the rush of fluid or gas, and lessens the likelihood of tool string damage by providing for slow equalization of high differentials.
  • The seal stack is manufactured from proprietary, high strength, nonelastomeric compounds that are chemically inert and 30% stronger than commercially available materials. Rather than becoming hard and brittle or bonding to the metal, as is the case with elastomeric materials, our seal compound actually behaves as a lubricant, alleviating seal bonding problems.
  • Mill slots replace drill holes as flow ports on both the housing and the insert to allow more flow area, reduce erosion and allow higher torque and tensile strength through the sleeve.
  • Locating the threaded connection inside the primary seal stack eliminates the need for O-ring thread seals and cuts the number of potential leak paths in half.
  • A locking, angled torque shoulder replaces traditional square shoulder to allow higher torques and reduce thread back-off.
  • Modular design permits conversion from a Model CMD™ to Model CMU™ or vice versa by only changing the upper and lower subs.
