The Moose limbs want more market share. They feel that they have carried our water for so many years that they are owed it. They cant survive with $22 oil. They think by bankrupting a few fracers in the Permian that they will succeed. The only problem is that the companies that ride the storm out will just buy up the assets. Barring a world wide collapse, this will be short-lived. IMHO.
Bankrupt China would be best.
Saudis need higher oil price than US, Russia or Nigeria because there are thousands of nobles who love their golden toilets and diamond-plated Lambos. And they have no sources of income besides oil, no matter how much more affordable the actual extraction is.
The problem with killing frackers is the low cost of conserving the source and bringing it back online. You might very well bankrupt the current owner with $22 oil but once it back to $60 another one would be pumping off the same site in no time.
