America is now the world's swing producer, because our drillers are more sensitive to market pressure than the sovereign producers of OPEC or Russia. If supply becomes tight, American producers can very quickly ramp up production and then shut it in again when demand falls. There's also no reason to believe that further technological innovation won't further reduce the costs of American production, especially in tight oil. Nobody thought that was even possible 15 years ago, today everyone in the country has an opinion on fracking.
Domestic producers have already shown tremendous resiliency in the face of the current glut—the smart ones have learned to cut costs in the same way the Seven Sisters did during previous oil crises. The fortress balance sheets of the majors will also shield the industry and allow continued R&D investment.
Furthermore, America's mature capital markets will ensure that capital is available to the new industry of independent producers driving the surge in domestic production. They can quickly respond to market signals and demand rises and falls.
Higher cost drillers will go bankrupt, the smart ones will survive and buy up the assets of the fallen.
