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:

    “There was an old woman and she lived in a shoe,
    She had so many children, she didn’t know what to do.
    She crumm’d ‘em some porridge without any bread
    And she borrowed a beetle, and she knocked ‘em all on the head.
    Then out went the old woman to bespeak ‘em a coffin
    And when she came back she found’ em all a-loffing.”
    —Mother Goose (fl. 17th–18th century. There was an old woman who lived in a shoe (l. 1–6)
