Field Transfer Question in Texas

Apologies if this is a simple question, but I just saw that one of our operators submitted a field transfer for one of our producing wells. It’s been a lackluster well that was drilled in 2013. It was originally drilled for the “Wolfcamp (Trend Area)” but is now “Phantom (Wolfcamp).” Does this indicate any new drilling/activity, or is this merely a legal formality?

Thanks for any insight!
