Well characteristics

Across the wells Cni has drilled, the median depth is 20 ft (middle half 18 ft–21 ft), median tested yield 19 gpm, and median static water level 13 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

Original drilling logs

Recent well logs filed by Cni, straight from the public MBMG record:

"Records span 1989–1994" 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.
