Abstract. Section milling and pilot milling are similar in that both operations mill away large sections of casing or pipe, but they are not the same. 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 ...
