That's what they do. If a well isn't producing enough to make it worthwhile, they shut it down. Or if there is a huge surplus of oil on the market, that drives prices down, and they shut off some flow to bring it back up.

Those multi-million dollar salaries and bonuses don't grow on trees ya know.
