I am currently taking Petroleum Engineering tech at SAIT and am taking Drilling 3, however my instructor has no idea what he is talking about...
This will be an odd thread, however I have a few questions I need answered about both casing drilling and under balanced drilling.
If there is anyone here who can answer a few questions, and they are technical, please PM me.
If not I will get in contact with a Drilling company directly.
Thank you
