Well characteristics

Across the wells Unison Drilling Inc. has drilled, the median depth is 1,014 ft (middle half 418 ft–2,434 ft), median tested yield 200 gpm, and median static water level 193 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

"Records span 2010–2019" refers to the earliest and latest well logs attributed to this company in the TDLR/TWDB database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
