Well logging
Well logging

Well logging, also known as borehole logging is the practice of making a detailed record a well log of the geologic formationsrated by a borehole.The log may be based either on visual inspection of samples brought to the surface geological logs or on physical measurements made by instruments lowered into the hole geophysical logs.Some types of geophysical well logs can be done
