Wellbore liner system

A wellbore apparatus comprising

• 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,
• the sleeve movable so the bottom end thereof contacts the diverter, and the diverter directs the sleeve to the window and through the window into a bore extending beyond the window,
• the window having an edge therearound to which the top end of the sleeve is weldable to effect sealing securement of the sleeve at the window,
• wherein the sleeve is welded to the window's edge by a welding apparatus, and
• anchor apparatus for anchoring the tubular member in the bore.

A method for installing a sleeve in an area extending from a main earth bore, the method comprising

• introducing a wellbore apparatus into the main earth bore adjacent an opening of an area extending from the main earth bore, the wellbore apparatus comprising a tubular member with a top end, a bottom end, a hollow portion, and a window therethrough, a movable sleeve positioned within the hollow portion of the tubular member, the sleeve having a top end and a bottom end, a diverter for directing the sleeve to the window and through the window into an area extending beyond the window, and the window having an edge therearound to which the top end of the sleeve is weldable to effect sealing securement of the sleeve at the window,
• moving the sleeve to co-act with the diverter,
• moving the sleeve into the lateral bore, and
• effecting a seal around the edge of the window by welding the top end of the sleeve to the edge of the window.

A wellbore apparatus comprising

• 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,
• the sleeve movable so 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 and activatable sealing material disposed around the edge to effect sealing securement of the sleeve at the window,
• wherein the activatable sealing material is a stored energy medium,
• an initiation device for activating the stored energy medium, and
• anchor apparatus for anchoring the tubular member in a bore.

A method for installing a sleeve in a lateral bore extending from a main bore, the method comprising

• introducing a wellbore apparatus with a window into the main bore so that the window is adjacent an opening of the lateral bore, the wellbore apparatus comprising 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, the sleeve movable so 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 and activatable sealing material disposed around the edge to effect sealing securement of the sleeve at the window,
• moving the sleeve to co-act with the diverter,
• moving the sleeve into the lateral bore, and
• effecting a seal around the edge of the window by activating the activatable sealing material.
