The rock column here is what drillers wrote down, layer by layer, in their own words — 5,345,462 layers across 707,856 wells. It is not a geological survey: two drillers may call the same clay by two names, and this site does not correct them.

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.
