Les, Just came in off of a rig doing underbalanced drilling. What UB drilling is actually IMO is a controlled blowout. But it's nice because it does not jam overweighted muds downhole into potentially producing formations and drills rapidly.

What does that mean moving forward. Drilling wells underbalanced will lower the cost of drilling a new well, and maybe on the negative side make frac jobs less necessary if you do not plug up the producing formation whilst drilling with heavier drilling muds....

Sincerely,

Doug F.
