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.

Latch mechanism guide

Wellbore apparatus has been invented which, in at least certain aspects, includes a wellbore apparatus having a tubular member with a top end, a bottom end, a hollow portion, and a window therethrough, a sleeve positioned within the hollow portion of the tubular member, the sleeve having a top end and a bottom end, a diverter apparatus within or outside the tubular member and, optionally, below the bottom end of the sleeve, the sleeve movable so that the diverter, and the diverter directs the sleeve to the window and through the window into a bore extending beyond the window, and the window having an edge therearound to which the top end of the sleeve is weldable to sealingly secure the sleeve at the window.

Wellbore liner system

Wellbore liner apparatus has been invented which, in one aspect, includes at least one tubular member for lining at least part of a lateral wellbore extending from a primary wellbore in the earth, at least one coupling bushing connected to the at least one tubular member and disposed in the primary wellbore, the coupling bushing having a bore therethrough from a top to a bottom thereof. In one aspect, the wellbore liner apparatus has two coupling bushings and a first tubular member and a second tubular member, the first tubular member secured to and extending down from the first coupling bushing to the second coupling bushing which is secured thereto, the second tubular member secured to and extending down from the second coupling bushing, with part of the second tubular member lining the lateral wellbore. Such systems are combinable with a wellbore milling system so that communication between the primary wellbore and the interior of the liner may be reestablished.

Wellbore milling

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.
