Every figure on this site is a **median**, never an average. On reported yield the average is twice the median, because a handful of entries are typing errors — the largest reads 2,200,100 gallons per minute against 30,078 for the next one. Yields above 3,000 gpm (136 wells, 0.045%) and depths beyond 5,000 ft (103 wells, 0.016%) are kept in the file, marked, and left out of the medians.

### Drilling a well in Hill County?

Depth is only half the quote. What it costs depends on the rock, the casing and the pump. Tell us where and we pass the request to licensed Texas drillers.
