Original drilling logs

Recent well logs filed by Heersink Drilling, straight from the public DWR record:

"Records span 2002–2026" refers to the earliest and latest well logs attributed to this company in the DWR database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
