    摘要: A wellbore mill has been invented that has a body having a top and a bottom and a first fluid flow channel extending longitudinally therethrough from top to bottom, the first fluid flow channel having an upper end and a lower end, the lower end of the first fluid flow channel having an opening sized for receiving a core of material from a tubular member milled by the mill, and at least a portion of the first fluid flow channel offset from the remainder thereof to facilitate separation of the core from the tubular member. 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 a mill on a working string into the wellbore at a selected desired point for milling the opening in the tubular, the mill comprising a body having a top and a bottom and a first fluid flow channel extending longitudinally therethrough from top to bottom, the first fluid flow channel having an upper end and a lower end, the lower end of the first fluid flow channel having an opening sized for receiving a core of material from a tubular member milled by the mill, and at least a portion of the first fluid flow channel offset from the remainder thereof to facilitate separation of the core from the tubular member, and rotating the mill to mill the selected tubular, create the core by thus milling the tubular and separating the core from the tubular being milled.

    摘要: An apparatus and method for guiding a fish into engagement with a latch mechanism on a fishing tool, by expanding the ends of a set of fingers into contact with a bore hole. The ends of the fingers surround the fish and guide the fish and the latch mechanism together, as the tool is lowered, until the latch mechanism latches onto the fish.
