How to plan for drill bit jet nozzles size

For many years, drilling engineers have known that hydraulics play an important role in cleaning the face of the formation so that a bit can drill faster. This first became evident when larger pumps increased the drill rate because more mud was being pumped through the large throat of the regular circulation bit. Jet bits were developed to improve on the jetting action of the high mud velocities at the bit.
