Texbanker, I know very little about drilling except it's very expensive and very amazing what they can do down hole be it directional drilling, fishing, or whatever. And I imagine the rig service companies are pretty responsive (if you pay your bills) considering 1000's of dollars for down-time.
Cash is King until further notice!!!
My comments on companies are usually my opinion of long term success (years). The PPS may go up or down greatly in the meantime depending on the number of greedy suckers with money.
