Casing Shoe

In oil drilling and borehole mining, a casing shoe or guide shoe is a bull-nose shaped device which is attached to the bottom of the casing string. A casing hanger, which allows the casing to be suspended from the wellhead, is attached to the top of the casing.

Famous quotes containing the word shoe:

    “one is in a shoe factory cursing the machine,
    one is at the aquarium tending a seal,
    one is dull at the wheel of her Ford,
    one is at the toll gate collecting,
    one is tying the cord of a calf in Arizona,
    one is straddling a cello in Russia....”
    —Anne Sexton (1928–1974)
