ice plug |

|
An ice obstruction formed by a circulation medium freezing inside the
drill-rod couplings while the rods are racked up or standing in the drill
derrick or tripod in extremely cold weather. Such plugs may loosen when
rods are lowered into the borehole and may be ejected from the open end of
the rod with enough force to injure drill crewmembers severely.
