n: The quotient of well total depth divides total time including productive time, nonproductive time, and rig releasing and installing time.

n: 1. the distance to which a well is drilled, stipulated in a drilling contract as contract depth. Total depth is the depth after drilling is finished. 2. on offshore drilling rigs, the distance from the baseline of a rig or a ship to the uppermost continuous deck. 3. the maximum pressure that a diver attains during a dive. expressed in feet (metres) of seawater.

n: The depth of drilling or The position of down hole equipment or operation in the wellbore.
