Original drilling logs

Recent well logs filed by ED Nelson, straight from the public Ecology record:

"Records span 1993–2007" refers to the earliest and latest well logs attributed to this company in the Ecology database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
