When milling casing, the intent is to cut a window through the side of the casing or to remove a continuous section of the casing so that the wellbore may be deviated from the original well through the window or section removed. depending on the type of grinding or metal removal required, the shape of the cutting structures of mills varies.

Its advantage over section milling is that less cutting debris needs to be circulated out of the well. the need for a larger casing window. performing a casing exit to create a secondary wellbore involves a whipstock assembly to direct the mill toward the side of the existing casing, where an exit is then milled.
2. consult casing string tally to establish position of casing collars and casing jewellery. the section to be milled should start either 5 ft above or 15 ft below a casing collar to avoid the casing backing off from the coupling. plan to mill as few casing collars as possible and finish the milling above a coupling.
Casing section mill. the positive stop system on the bottom of each section mill blade stabilizes the cutting blades for higher penetration rates. tungsten carbide cutting elements are formed in a polygon shape and incorporate a chip breaker to eliminate stringers. all section mill tools are manufactured using 4145 aircraft quality steel billets.

Some of the key challenges to a successful single or dual string section milling operation are eccentric casing strings, either cemented or uncemented, can result in skimming or troughing of the outer casing, often resulting in a more complex, costly abandonment. inadvertently puncturing the outer casing string thereby compromising the integrity of the wellbore further and introducing more

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 point where milling stops.
