Good pics by the way (as most of yours are).We've lived in this area now since Fall of 2018 with no drilling rig set up there in that length of time.
I wondered if it was fracking, but when looked at images online for that term, all of them had a "derrick" at the site, thus the reason for supplying pictures. This has been going on here for about 2 weeks (I think).
Are they working around the clock? Most completion work is 24 hr ops, but there are some areas that are “day shift only”.
