Abstract: A wellbore mill has been invented that, in certain aspects, has a body having a top and a bottom and, optionally, a fluid flow channel extending therethrough from top to bottom with, optionally, one or more fluid jetting ports in fluid communication with the fluid flow channel, milling apparatus on the body including a plurality of milling inserts, each insert mechanically secured in a corresponding recess in the body, said mechanical securement sufficient for effective milling in a wellbore. A wellbore milling method for milling an opening in a selected tubular of a tubular string in a wellbore has been invented that includes installing and using such a mill.

Abstract: A wellbore tubular patch for patching a hole in a wellbore has been invented, the tubular patch in certain aspects having an expandable top member having a hollow tubular body and a top end and a bottom end, an expandable bottom member having a hollow tubular body and a top end and a bottom end, an expandable outer sleeve in which is secured a portion of the bottom end of the expandable top member, and a portion of the top end of the expandable bottom member inserted into and held within expandable outer sleeve. A method for making a tubular patch for patching a hole in a tubular in an earth wellbore has been invented, the method in certain aspects including securing a portion of a bottom end of an expandable top member in an expandable outer sleeve, the expandable top member having a hollow tubular body and a top end, and securing a portion of a top end of an expandable bottom member within the expandable outer sleeve, the expandable bottom emmber having a hollow tubular body.
