Liner Hanger - an overview ScienceDirect Topics

3.4.1 The liner hanger. A liner hanger, as the name suggests, secures and supports the liner. It uses mechanical slips to grip the inside of the casing a pre-determined distance above the casing shoe. The space between the liner hanger and the casing shoe is called the liner lap. Liner hangers can be set hydraulically, mechanically, or a mixture of the two. Most liners are cemented back to the liner hanger.

Pilot Mill - DrillingForGas

On most liner milling jobs, a pilot mill is used to mill the liner hanger, or adapter, and then the liner. In some cases the liner hanger, or adapter, is milled with a junk mill, and then the liner is milled with a pilot mill. This latter method is preferred if there is hard cement behind the liner or if the hanger has numerous bow-springs, slips, etc. A pilot mill with blades that will cut just over the pipe couplings
