There are loads of wells that produce small amounts of helium. Mostly in New Mexico. The problem is the economics of separating and capturing it. This process is spreading, e.g., to Kansas and Oklahoma, as the price increases.
Of course, if you want loads of helium, just build a space elevator.
That is not an inconsequential problem. Using cryogenics to separate out helium require cooling down to below -346°F where the nitrogen condenses out of the gas remaining after the methane condensed out at -260°F
