Milling Casing Method

The Guide to Oilwell Fishing Operations | ScienceDirect

Section milling creates an exit point in a string of casing that is equal to the bit size of the casing being milled. Pilot milling completely removes an entire casing string from the top to the point where milling stops. The resulting hole is larger than the outside diameter (OD) of the casing being milled.
