Definition An exercise on a drilling rig that is supervised by the tool pusher and is designed to make the driller aware of the fluid level in the mud tanks. Without warning to the driller, the float in the mud tank is raised or lowered. The time that the driller takes to notice the pit level change and, if drilling, signals to pull up the kelly is recorded on a Pit-o-Graph. Less than 1/2 minute is acceptable.
