Well Drillers Near Shelby, Michigan

A geological estimate for the Shelby area.

Detailed Summary

A representative geological profile for the Shelby region (Oceana County, MI) consists of an upper sequence of sand (sometimes interbedded or overlain slightly by topsoil), underlain by alternating sand-and-clay or sand-and-gravel layers. Most wells transition through 1–2 significant clay or clay-rich horizons, followed by thick, laterally extensive sand or sand-with-gravel units that are the principal water-bearing formations and main residential supply aquifers. The most common well construction practices involve rotary mud drilling with casing set typically to ~45–60 ft, and screened intervals located in the deepest sand layers. Typical static water levels range from 5–35 ft below grade depending on elevation and season. Residential wells (5–15+ GPM) are usually 35–65 ft deep; high-capacity wells and those in clayier settings may require depths up to 110 ft to reliably intersect productive sand aquifers. Outlier values or unusual lithologies were omitted to reflect the general stratigraphy found in the majority of sampled logs.
