Pump Out Reamer Shoe

A custom made Pump Out Reamer Shoe has been designed and manufactured for one of WEP’s Salt producing clients. This shoe was part of a 5” liner which was run in after drilling a 300m sidetrack into an existing live cavern with a pressure of 400 bar @ 2420m measured depth. The special design features are that the shoe can be remotely disconnected. For rotational actions the shoe and bottom sub are machined with a torque arresting geometry. The shoe has a weld-on tungsten carbide hardfacing for wear reduction and possible reaming functionality. To prevent backflow the shoe contains a  off the shelf double barrier. The shoe has successfully been run with a HWU unit into the pressurized cavern.
