Patent abstract
The present invention relates to a diverter tool used in a pipe string to lower a liner into a partially cased wellbore. The diverter tool has a diverter body that defines a longitudinal central flow passage and has diverter ports defined therethrough to communicate and redirect fluids received in the liner to an annulus between the diverter tool in casing previously set in the wellbore. The diverter tool has first and second closure members. The first closure member is movable between open and closed positions on the diverter body. The second closure member is detachably connected in the diverter body in its open position and is movable to its closed position to prevent flow through the diverter ports.
