How blind drilling is done at a rig?

In: Mechanical Engineering [Edit categories]

Answer:

If you are drilling with no returns it is imperative to watch pressure, torque and hookload. Before every connection ream the pipe at least half way to make sure you are free. Connection time is imperative, any sign that pressure cannot be maintained or that the string is not free pull out of the hole until pipe is free and try to regain pressure. If TD is reached on the hole and casing is run cement tools such as a cement basket, ecp or acp will need to be figured based on estimated geological data.
