They won't reach capacity, and capacity should increase with all these new pipelines etc. When they get close to full, they will just shut down more rigs. These guys know what they are doing. Where do you think all that gas is currently going from those rigs already drilled but not hooked up to the east and north east coast?
The producers keep pumping because they have fixed costs they want to cover. Some revenue is better than no revenue as the fixed costs don't go away. Otherwise they would have cut back last week. Storage is going to be an issue - Perhaps all the way through winter.
