Geological drilling.

The samples collected in course of drilling are used to prepare geological log or litholog or strata chart. In water wells, logs are likely to give (i) the thickness of the aquifer and (ii) depth to the porous and permeable zones. Drilling time log acts as a supplement to geological log which gives penetration rate and bit behaviour.
