Liner Top Test Tools

Tools run as part of the main wellbore clean-up string which are used to test (negatively) one or more liners/liner packers all the way to the shoe track. Some tools are used to scrape the casing to below the integral packer setting area as well as to dress off the PBR (Polished Bore Receptacle) at the top of the liner. Some tools also effectively cross over one size of pipe to a smaller pipe size inside the liner.
