ABSTRACT:
A wellbore mill has been invented having a flexible main body, and at least one milling apparatus secured on the flexible main body. A wellbore mill has been invented having a main body with a top end and a bottom end, at least one milling structure on the mill body, and a stinger projecting down from and releasably secured to the bottom end of the mill body. Methods have been invented for milling wellbore tubulars with such mills. A method for eliminating tubular offset in a wellbore has been invented, and the method includes positioning a wellbore mill in a tubular offset of a tubular string in a wellbore, the wellbore mill comprising a flexible main body and at least one milling apparatus secured on the flexible main body, and rotating the wellbore mill to mill at least part of the tubular offset.
