shutin

With natural gas prices hanging at numbers around $2.50/MMbtu and possibly headed lower, there is a lot of talk about shut-ins.  Presumably going out to the wellhead and turning off the valve.  A couple of weeks ago, Jim Hackett, Anadarko CEO told a Rice University audience that “at current gas prices, gas operators can't sustain profitable domestic operations. By shutting in some of their wells, prices quickly would rebound.”  Is that true?  Is it a good idea?
