Everyone calm down. I can guarantee the reason the rig was evacuated was that gas was on the rig floor so they shut down what they could and got everyone out in case the gas hit an ignition source. It looks like the gas has ignited so what happens next?
For one, it's gas... Last time I heard gas can't "spill" so everyone asking if it has the potential of being a Macondo can be relieved. It's lighter than air!
Second, while a large portion of gas wells on the shelf are low pressure, the current A-3 well is producing in the 11500' Sand. Current Bottomhole Pressure reported is approx. 7600 psia (Initial Res. Pressure is around 9200 psia) so abnormally pressured reservoir. Best case scenario here is the pressure drops to the normal pressure range, the rock grains contact each other again and fines move into the wellbore and sand the well up.
Third, it seems like the Hercules and Walter crews did their job as best they could to minimize damage and loss of life. Let's be thankful everyone got off alive.
ST 220 is in Federal Waters for anyone trying to look for well and field data on SONRIS (you won't find it on Sonris which is a state website).
