Original drilling logs
Recent well logs filed by Dennis, straight from the public MGS/MDH record:
"Records span 1991–2026" refers to the earliest and latest well logs attributed to this company in the MGS/MDH database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
