Renown’s ‘RPOB’ or Retrievable Packoff Bushing creates a seal between the setting tool and the liner. All RPOB’s can be dressed for most well applications including thermal and sour. With locking and self releasing lugs, the bushing is removed with the liner running tool. The ‘RPOB’ is compatible with Renown’s ‘RDS’ running tool, ‘AP’ running tool and J-run tool.
