What’s the Minimum PSI for Borehole Stability in Mud Rotary?
We have a question this week about mud drilling. What’s the minimum psi you need to keep a stable borehole in a mud rotary hole? It’s Ask Brock 231.
“I think the more important question here is, What do I need to maintain borehole stability?” Brock says. “That is a low-solids drilling fluid that is moving in the right direction, which is up, and is able to facilitate these cuttings to fall out at surface or for a solid control system to separate them out.”
He explains that once you zoom out to the bigger picture in that way, you can understand how to get to (and maintain) a good psi downhole.
