>>the USA does not have enough gas wells anyways to supply Europe

The US has the output - but lacks liquefaction facilities and pipelines run from shale oil wells to any of those facilities, or if liquefaction is co-located with the wells, a way to transport LNG to the coast and a way to get that onto LNG transport vessels.

As it is, there's so much methane being 'flared off' in the Permian and Bakkan fields that the flares are visible from the ISS at night. (flaring is done because the byproducts CO2 and H2O are less climate damaging than methane - and, as it is, there's too much methane leaking past that).

That said, production from shale oil has a much shorter lifetime than that of conventional wells, so investment in pipelines may or may not make any sense. And I'd much prefer to see the world (including Europe) move away from burning things for energy.

TL;DR: yeah, but... it's complicated. :-)
