Reduce drill out time, improve casing shoe ability.

Rubicon’s BridgeBUSTER® offers a range of options for increased drilling efficiencies and reduced NPT. The shoes protect casing integrity, make it possible to ream to planned TD and facilitate casing runs and cementing. The BridgeBUSTER® is a reamer shoe designed to be run on the bottom of the casing or liner to enable strings to be washed, rotated and reamed to planned TD. The BridgeBUSTER® fitted with the FastDRILL nose reduces the time required to drill out while still maintaining high compressive strength.

Making it better

The BridgeBUSTER® increases probability of casings and liners reaching planned TD.

Can be run in conjunction with a NaviGATOR to provide end of casing rotation when the full string cannot be rotated. Minimizes the risk to BHA. Improves casing shoe ability. Reduces the risk of damage to the casing shoe integrity with its fast drill out time. Provides low cost improvement in operational efficiency. Improves bit performance.
