The Well Log is a Bore Hole Image. It is record of a continuous in-situ down hole measurement of the physical and structural properties of a penetrated formation.
Modern day technology in oil/gas/mineral exploration utilizes a variety of probes (instruments) either singularly or in combination (stacked). Each of these well log types is utilized based on the objective selected for solving the exploration and development problem.
Learning Objectives
