The Liner Tieback Packer is a liner top packer that is most frequently run on drill pipe using a mechanical setting tool and a tie back receptacle liner setting sleeve with tieback extension. The packer is run to the top of an existing liner tieback extension, and the seal stem is inserted until seated and pressure tested down the drill pipe. Additional set-down weight shears the release pins and sets the packer seal. The setting tool is released with right hand rotation. The tieback stem on the Tieback Packer has three sets of glass-filled Teflon Chevron seals for severe pressure and temperature applications. It features ratchet lock in the setting shoulder to prevent premature setting while running in. Maximum seal integrity is assured by a threepiece rubber sealing element contained by metal back-up rings. Hold down slips and an internal body-lock ring maintains seal compression and prevents floating of short liners. The Tieback Packer can be released by cutting the inside mandrel in the designated area. Tieback receptacles are available with this packer in different lengths e.g.: 6 ft, 10 ft, 15 ft, 20 ft etc as per requirements or demand from customers. Available in rotating or non-rotating configuration with retrievable or no cementing bushing profile running and setting, this assembly may be configured with conventional mechanical right hand release running tool, rotating mechanical running tool or hydraulic release running tool. The packer is furnished with higher group of API 5CT standard materials as well as with the end connection in compliance to API standards or any premium threads as per the customer’s requirement/demand. CRA materials suited for H2S or CO2 service are available on request.
Features / Benefits :

• Liner top packer run on drill pipe after the liner is cemented.
• Used to prevent micro-annular gas leak at liner top.
• 3-Piece seal element provides high pressure/temperature.
• Integral body lock ring holds a positive set in the seal elements.
• Ratchet lock feature prevents premature set while running in the
• hole.
• Glass filled Teflon Chevron seals provide high temperature/pressure
• tie-back capabilities.
