Abstract
The apparatus of the present invention provides a top drive supported tool for making up and running casing strings into a borehole. The tool comprises a fill-up and circulation assembly and a launcher assembly that is adapted to cooperate with a connectable cement wiper plug assembly for launching wiper plugs that control cement placement in the annulus between a casing string and a borehole containing the casing string. The tool of the present invention shortens or eliminates delays in well operations, thereby improving integrity of cement liners formed by placing cement slurry in a targeted interval.
