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:
“I was put into jail as I was going to the shoemaker’s to get a shoe which was mended. When I was let out the next morning, I proceeded to finish my errand, and, having put on my mended shoe, joined a huckleberry party, who were impatient to put themselves under my conduct; and in half an hour ... was in the midst of a huckleberry field, on one of our highest hills, two miles off, and then the State was nowhere to be seen.”
—Henry David Thoreau (1817–1862)
