You seem to interpret this as a problem. However, I've read many times that it's basically a solution, because what it means is that production is responsive to demand in a far shorter timeframe than conventional oil. On top of that, supposedly you can drill a well and not complete it until a price war is over.
So I'm not sure why you think "non conventional oil industry is [doomed] to go bankrupt" when not only do people in the industry say it is relatively easy and cheap to put resources on hold, but obviously the sources of conventional cheap oil tried their best to kill the newcomers and failed, only a few years ago. According to both theory and recent history, your prediction doesn't make sense to me.
However, I have no experience whatsoever in the industry, so maybe you have some expertise?
- demand is destroyed by coronavirus - prices go down (maybe as low as $10 a barrel according to some analysts) - existing wells maybe kept pumping, or not - new drilling stops, ditto exploration, etc. - cash flow in tight oil industry falls to about zero - huge debt (trillions) can't be paid back, companies go belly up, banks must be rescued by the Fed...
several scenarii open up from there: would the Fed rescue the oil companies? may the government nationalise the oil industry? What can be the impact on US$? On US debt? financial markets? Who knows, all bets are off at this point.
The crucial moment will be there: in the few months between this moment when the shale oil industry defaults on its debt, and when it's bought back (debt free, therefore in a sane situation), there may be a large gap in production, that could kill world oil demand by sending prices through the ceiling ($100 barrel? $120? $150?) because normal demand can't be fulfilled by conventional production anymore.

I myself have no particular expertise, but I've been following quite closely oil and energy since 2005.
However shale oil requires constant drilling because production rises then falls very quickly (18 months to 2 years). With low oil prices, drilling will dry out and oil will dry out soon, too. Plus total oil production (conventional + non conventional) will probably peak anyway in the next decade (see WEO 2018, once again), and this may be quickened by the coming lack of investment due to low oil prices.
What could happen? With low demand and low price, the non conventional oil industry is deemed to go bankrupt, and the US banks will have to part with trillions of debt. That won't be pretty. Until this industry is rescued and starts pumping again, there could be a severe crunch of oil production, initiating an oil shock and a huge recession, sometimes in the coming next few years.
