Well drilling is a crucial process that involves creating a pathway to access underground water sources. Whether you are considering drilling a well for residential, commercial, or agricultural purposes, one of the primary concerns is the c...Drilling progress should be recorded while drilling; recovery can be improved by relating recovery to optimum pressures and speeds, as well as providing data for interpretation. For each run, the driller should record the time when starting to drill and when stopping to come out of the hole. Most of these drilling progress data are qualitative ... 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.
