  • Oil Drilling
  • Boring and Drilling (Mines)

A measure of the speed with which the bit drills into formations; usually expressed in terms of feet per hour.


Drilling rates can often be increased by using water to circulate the cuttings from the hole; when feasible, the use of gas as a drilling fluid can lead to drilling rates as much as 10 times those attained with mud.


Improved lubricity by addition of oil and special proprietary additives can contribute to longer bit-life and increased rate of penetration.
