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:

    “Wynken and Blynken are two little eyes,
    And Nod is a little head,
    And the wooden shoe that sailed the skies
    Is a wee one’s trundle-bed.”
    —Eugene Field (1850–1895)
