This article from 2 days ago says they have a test rig that is drilling outside. They don't say exactly how deep they have drilled but mentions they have another site where they will attempt to drill up to 100 feet.

So sounds like they are at the very beginning of piloting. I'm not going to listen to an hour podcast to see if it is claiming anything different, if you have a text source I'd be interested.
