Type B Cementing Shoe

Type B Cementing Shoe

The IRI Type B Basket Cementing Shoe of casing is employed two ways. First, as both a Shoe to protect the Running-in String even through irregular and deviated holes. Second, a Basket to protect the formations below the shoe from cement contamination in the open hole, in washed out sections, in under-reamed and bell holes and/or in zones determined too weak to support the weight of the cement column alone.

  • Economical
  • The Shoe permits circulation through the guide nose while running in.
  • The Basket is held tightly against the core mandrel by a petal retainer for running in clearance.
  • After the setting depth is reached, the ball is dropped to release the basket petal retainer.
  • The ball gravitates to the seat, stopping circulation through the shoe. This diverts all the pressure to expanding the basket.
  • IRI Type B Shoe Baskets are made of Spring Steel Ribs reinforced with overlapping rubber Liners, which allow the expanded tool to better conform to the shape of the hole.
  • All internal parts of the shoe are drillable.
