Original drilling logs
Recent well logs filed by Kouba Drilling LLC, straight from the public WI DNR record:
"Records span 2002–2026" refers to the earliest and latest well logs attributed to this company in the WI DNR database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
