Original drilling logs
Recent well logs filed by Krass Drilling & Pump Service, straight from the public MBMG record:
"Records span 1960–2013" refers to the earliest and latest well logs attributed to this company in the MBMG database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
