What is the primary function of a well log?

The primary function of a well log is to record important details about well construction. This log documents various aspects of the well, including its depth, the types of materials used in its construction, the geological formations encountered, and any significant events that happen during drilling. This information is crucial for future reference, maintenance, and understanding the hydrogeology of the area.

Well logs serve as vital records that can help assess the well's capacity, the integrity of its construction, and whether it meets regulatory standards. By having detailed records, water well professionals can make informed decisions regarding the well's operation, any required repairs, and the overall management of groundwater resources. The emphasis on well construction details in a well log helps ensure that wells are safe and efficient for water extraction.
