No, it is not simple, nor are there “hundreds of wells doing it”. (yet)
BTW; the wells are not doing anything, nor is it complicated to drill them.
What is complex, new and costly, is the infrastructure, from the source to the wells.
The people that develop, work and manage these projects are not idiots. They study the problems, find solutions and invent the methods and equipment required to do the job as safely and cheaply as possible.
