AERATED & FOAM DRILLING MUD
Objective: Air, Aerated, and Foam Drilling Mud Applications Aerated fluids used in drilling operations include air, natural gas, mist, foam, or aerated muds. These fluids allow high penetration rates because of the reduced hydrostatic pressure, thus allowing the drilled rock fragment to explode into the wellbore. Lost circulation problems are minimized when using aerated fluids. …
