A well that produces 1 barrel of oil per week, and 20 gallons of water per day is going to be shut down. It is a constant expense, the disposal cost will exceed the oil production cost.
It isn’t about making oil, it is about making money.
But a barrel of oil a week leaking into your drinking supply is a really bad thing.
Still doesn’t answer my question. Why cap a well that requires mechanical action to lift the oil to the surface? It it has a valve head on it. Just shut it and wait for oil prices to go up.
