Qatar makes 95% of their revenue on LNG. These are long-term contracts at fixed prices. Kuwait and Qatar also have the fewest amount of actual citizens that it would need to "pay off".

Ex: During the Arab Spring, Kuwait handed out $500k checks to all Kuwaiti males above 18 years old. He also told the citizenry that he would forgive all car loans - population went and bought ferraris, range rovers, etc. and got the loans all forgiven by the government.

I worry more about the Arab countries that have high populations and cannot afford to pay everyone off - Saudi is on that list.
