In some ways it is, but probably not at who you think.
Saudi Arabia, UAE, Kuwait, Qatar have had better control of their spending and building up cash reserves compared to the other members of OPEC. Saudi in particular is no longer interested in cutting their production and loosing revenue and market share, to support the over spending of the other members.
Saudi is a massive spender, hard to believe they could criticize others of too much government spending. But they also built up their cash reserves to prepare for this time. Iran, Venezuela, Nigeria are in a far bigger world of hurt than US oil producers in general.
In fact, Qatar and the UAE now realize they need to be more than just big oil producers to be prosperous. That’s why both countries are positioning themselves to be major players in trans-Eurasian world trade—in fact, the UAE has been planning for a post-petroleum age for a couple of decades, as noted by major expansions of air cargo operations at several airports in the UAE.
Think about it, an F-150 Ford Truck is approaching 30 MPG Highway, the future is consumption will continue to go down.
OPEC will die a slow death, run out of money and back to camels and sand!
