Reamer Family

Guiding casing and liner strings to total depth (TD) in openhole wellbores can be complicated by obstructions, such as ledges and bridges, and by unstable, sloughing, or swelling formations.

Reamer shoes use cutters to smooth the wellbore ahead of the casing and liner string, which reduces the risk of a short landing.


New DB Reamer Nose

Weatherford reamer shoes provide fullbore coverage in both rotating and reciprocating applications, which enables the easy passage of casing and liner strings to TD despite challenging hole conditions.

The tungsten-carbide cutting structures have a 360° cutting radius that clears wellbore restrictions and overcomes openhole bridges and well sloughing. Meanwhile, the rigid stabilizer blades keep the hole open and clear a path for the tubular string and centralizers to pass through.

The nose of the reamer shoe withstands impact loading and high set-down weight. Large, flow-directed ports in the nose circulate debris past the shoe and prevent channeling while pumping cement. The reamer shoe can be drilled out quickly using polycrystalline diamond compact (PDC) or tricone bits.

From our comprehensive portfolio, we select the right reamer to meet client needs. Weatherford reamer shoes include features that suit a range of formation types and applications: 

  • Noses can be composite or aluminum, eccentric or concentric, and free-rotating or fixed.
  • Reamer shoes can be built with baffle plates, single valves, double valves, or no valves.
  • Most noses contain internal drillout slots to avoid bird-nesting of material during drillout.
  • Large, multidirectional flow ports enable fullbore flow while running casing and liner strings in hole and during cementing.
  • A range of set-down weights and temperature ratings are available.
  • A range of body materials and threads are available.
  • Welded and nonwelded cutting structures and stabilizer blades are available.
  • Reamer shoes enable rotation and reciprocation.
     

Weatherford reamer shoes enable casing and liner strings to reach TD efficiently in challenging formations that would otherwise cause tubular strings to become stuck.
