Pro-ESI’s ProFrac Liner Top Packers are engineered with one piece mandrels complete with integral PBR, allowing the operator to tie-back the liner by utilizing Pro-ESI’s ProFrac Tieback Nipple Line. Eliminating the need to tie-back to a setting sleeve of a liner top mechanism dramatically decreases potential leak paths. The ProFrac Tie-Back Nipples guarantee a high quality seal, are ultra short and snap, lock or locate directly into the mandrel of the ProFrac Liner Top Packer.
There are three basic configurations of the ProFrac Tie-Back Nipples:
- Locator Type: Set down to enter PBR with seal and over pull to exit seal from PBR. (No rotation required)
- Snap Locator Type: Set down to enter PBR with seal and over pull by predetermined amount to ‘snap’ seal from PBR. (No rotation required). Note: release force has to be predetermined and pre ordered.
- Latch Locator Type: Set down to enter and latch Seal into PBR and over pull with ¼ turn of right hand rotation at the tool releases Latch Locator from PBR
- Note: only used when being run with jointed work string as rotation torque is required.
