Liner Hanger Accessories
Tie-Back Receptacle

Overview

When installing a Liner Hanger the Tie-Back Receptacle attaches to the Liner Top Packer and provides a sealing bore. This polished bore is used to tie the well back to surface, provide a sealing bore for fracturing operations or for landing a second trip packer in case of a liner-top leak.

Features

  • Sized to provide full bore ID for liner
  • Honed/Polished ID for reliable sealing
  • One-piece construction eliminates potential leak paths
  • Junk Cover latch relief for securing latching debris barrier
  • Standard lengths of 6, 10 and 15’. Custom lengths available
  • Standard materials are L-80, P-110, and Q-125.
  • Available in various other custom material grades
 
Tie-Back Seal Assembly

Overview

The Tie-Back Seal Assembly is a liner hanger accessory which allows the well to be tied back to surface. This seal assembly, once landed, forms a seal inside the tie back receptacle (TBR) located on the existing liner top preventing communication between the liner’s internal diameter (ID) and the annular space above the liner top.

Features

  • Multiple seal stacks for sealing within the existing liner top TBR
  • Integral locator positions the seal assembly properly inside the TBR
  • Lead wiper cleans bore minimizing debris on seal surface
  • Standard half mule shoe down
  • One piece mandrel
  • Full casing ID
  • Matching liner connections and material Available in various common lengths
  • 10,000 PSI differential pressure rating
 
2nd Trip Packer

Overview

A second trip packer is used to seal off any leaks in existing liner top. The second trip packer is run down to the liner top utilizing conventional liner running tools. The packer has an integral seal assembly which is stung into the liner top’s Tie Back Receptacle (TBR). Mechanical weight is then applied to compression set the packer’s element and hold down slips. The liner top will then be sealed off and the running string released and retrieved.

Features

  • Provides secondary liner top TBR
  • One piece mandrel
  • Multiple seal stacks for sealing within existing liner top TBR
  • Anti-preset trip nose prevents premature set while running
  • Metal core bonded elastomeric element seal provides anti swabbing while running and circulating down hole
  • Non-swabbing, bonded packing element
  • A premium double threaded locking ring system assures the packer stays firmly set and sealed Integral hold down slips holds tool firmly in place
  • Utilizes Frontier’s standard running tool and accessories
  • 10,000 PSI differential pressure rating for element and seal stacks
  • V3 Rated
 
Liner Wiper Plug

Overview

During the cementing process the liner will have to be wiped clean of leftover cement to prevent cross contamination between the cement and displacement fluid. The Liner Wiper Plug (LWP) is a rubber wiping device used in liner hanger applications. Attached to the end of the liner hanger running tool, the LWP is launched upon receipt of the drill pipe wiper plug. It also serves to wipe the inner diameter (ID) of the liner pipe to prevent sheathing or sticking of hardened cement to the inside of the liner.

Features

  • Ported design allows fluid venting in the annular space
  • ID latching profile receives drill pipe wiper plug
  • OD latching profile securely locks into landing collar. 5,000 psi pressure rating from above and below when plugs are latched
  • Locking feature prevents spinning during drill out
  • PDC drillable aluminum construction
 
Ball Seat Landing Collar

Overview

A Ball Seat Landing Collar is a component used when running hydraulic set Liner Hangers. The Landing collar is installed near the bottom of the liner string. This tool allows for the landing of a ball to hydraulically actuate up-hole tools. The landing collar also has a profile to stop and latch the liner wiper plug during the primary cementing operation, and a mating clutch design that prevents rotation during liner drill-out.

Features

  • Ball seat pressure is field adjustable without disassembly.
    • Adjustable shear up to 5,000 psi
  • Once ball seat is sheared, the ball and seat are contained within the landing collar so no debris flows downhole to foul the float equipment.
  • Aluminum internal parts are PDC drillable
  • Latching liner wiper plug profile:
    • 5,000 psi pressure rating from above and below when plug/s are latched.
    • Clutch profile prevents wiper plug/s from spinning during drill-out
  • Full casing ID after drill-out Matching liner connections and material on outer housing
  • Meets or exceeds liner tensile, burst and collapse ratings
 
Drill Pipe Wiper Plug

Overview

The Drill Pipe Wiper Plug (DWP) is a rubber wiping device used in liner hanger applications. Dropped from the surface, the DWP provides a means of separation between cement and displacement fluid (drilling mud) preventing cross-contamination during liner cementation. It also serves to wipe the internal diameter (ID) of the drill pipe to prevent sheathing or sticking of cement to the inside of the drill pipe.

Features

  • Field-customizable fin configuration
  • Latching nose locks and seals securely into liner wiper plug
  • Allows for proper displacement indication during liner cementation
  • Locking mechanism to prevent rotation during drill out
  • The flexible fins are available in most drill pipe and tubing size combination
