Do not stop the downward movement of the drill stem with the slips. This can cause crushing or necking down of the drill pipe tube. The drill pipe can also be damaged by allowing the slips to ride the pipe on trips out of the hole. Good rig practices will help eliminate time consuming trips in the future, looking for washouts or fishing for drill pipe lost in the hole. For more
