There’s at least 50 plus years before gas will run out. 

Only true with significant caveats. The stuff that flowed out of the North sea with minimal engineering effort from large salt caverns and made us rich in the 1980s is pretty much all gone.  We can push the remainder of it out now by injecting seawater under pressure but it is slower and an expensive and energy intense game.   There may be gas for sale from other countries whose politics we do not like who will probably have the easy to extract stuff for some decades to come, but they may not sell it to us so cheap when we have none of our own. 

Tightly trapped gas in small pockets that require fracking and other tricks to get it to the surface we have plenty of, but that is not so cheap as it needs a larger number of small holes,  and there are concerns about risks like contaminating ground water to consider.

Yes, there will be gas, but it may not be at a price we are so happy to pay as we have been used to. In fact I thing there will be some methane underground pretty much for ever, as it will be in places or deposit sizes that make it simply too hard to bother with, though as price rises that threshold of what is worth it also moves with it.

 edit some figures to back that up shale gas in the UK.. a report from 2018.

The break-even price at which shale gas can be sold varies between 0.95 and 114.44 pence/MJ, averaging at 9.47 pence/MJ, depending on the volume of gas produced by a shale gas well. The latter is two times higher than imported liquefied natural gas, around 30% more expensive than UK natural gas and three times greater than the price of US shale gas.

Not as clear as I would have stated it, and of course that was at 2018 prices. But back then it meant  that something like all but the bottom 10% or so of the larger and most  easy to extract deposits of  shale gas in the UK would cost more to extract than you could sell it for.

food for thought?
