482:, sliding is used to describe a drilling interval in which rotary drilling (i.e., turning the entire drill string) is ceased and a mud motor is engaged to drive the drill bit and provide directional control. Because sliding significantly decreases rate of penetration, increases bit wear, and increases tortuosity, it is normally limited to drilling lateral sections of a horizontal well.
365:
Hitch: Rig employees refer to their work period as a 'hitch.' A common hitch is 20 days on, followed by 10 days off.
