Liner setting sleeves are part of a series of setting tools that provide the physical attachment between a running string and liners. Our liner setting sleeves will increase the efficiency and reliability of our liner-running operations. The liner setting sleeve or liner top packer is run in conjunction with a liner setting tool. Together, they support the weight of the liner, allow liner top packer setting or rotation of the liner and provide a reliable releasing mechanism to detach the running string.
Our C2 liner setting sleeve provides a method with which the C2 setting tool can carry in and set a liner into the wellbore. The C-2 liner setting sleeve consists of a body with a coarse left-hand box thread into which the float nut of a C-2 Setting Tool is engaged, then combined with a honed tieback extension. After reaching setting depth, the setting tool is released with right-hand rotation of the running string. The C-2 Liner Setting Sleeve may be run with all hydraulic and left-hand set mechanical hangers, and is available in materials to match most casing grades.
The HRD-E setting sleeve is used in conjunction with the setting tool to carry the liner to setting depth when a liner top packer is not desired. It is a hydraulic release, collet-type setting sleeve. The HRD-E sleeve has a higher load rating than other hydraulic-release setting sleeves.
The sleeve design provides increased torsional capability when the liner must be aggressively rotated into the hole. The high load-compression shoulder accepts very high compressive loads, and five torque finger slots increase the torsional rating over equivalent hydraulic setting sleeves.
Our HR™ liner setting sleeve provides a method for the HR™ setting tool to carry in and set a liner into the wellbore. The sleeve is run in conjunction with an HR™ liner setting tool to carry the liner to depth. The sleeve has a collet profile that mates with the HR Setting Tool collet. The weight of the liner is carried on the collet, rather than on float nut threads. Slots are provided in the upper end of the setting sleeve body to accept torque transmitted from the torque fingers of the HR setting tool. Because the setting tool does not rely on rotation to release from the setting sleeve, the liner can be pushed, pulled, and rotated into the hole. The shallow entry bevel at the top of the sleeve allows easy passage into the liner. It is ideal for use in high-angle and horizontal applications.
The RH™ liner setting sleeve provides a method for the 2RH™ Setting Tool to carry in and set a liner into the wellbore. The RH Liner Setting Sleeve contains a threaded body into which the float nut of a 2RH Setting Tool is engaged. Slots are provided in the upper end of the setting sleeve body to accept torque transmitted from the torque fingers of the 2RH Setting Tool. Slackoff and right-hand rotation are applied concurrently to release the setting tool from the RH Setting Sleeve. This feature allows the RH Setting Sleeve to be run with hydraulic, left- or right-hand set hangers.
Our Model S sleeve with tieback extension is used when setting a liner and tying back to the surface is planned. When tieback is completed (two-stage long string), using the metal-to-metal tieback stem, the integrity of the liner top will be equal to the liner. Model S Sleeves are available with C-2, RH, and HR profiles, which are located near the top of the sleeve. The carrying profile and honed bore are constructed from one piece. You can select an optional metal-to-metal seal profile at the bottom of the honed bore to land a high-pressure/high-temperature tieback seal assembly.
