Oil producers are locked in mutual assured bankruptcy. As it is in the poverty trap, when price goes down, quantity must go up. Producers are locked in a death spiral - the lower oil prices go, the more is produced. The marginal cost of producing an incremental barrel of oil for existing wells is the limit approaching zero...
