สรุป	Hydrogeological survey is the systematic characterization of groundwater systems, including aquifer geometry, water quality, flow paths, and recharge-discharge dynamics. Rooted in Darcy's law (1856) and quantified by Theis (1935), this method is essential for water resource management, contaminant remediation, and hazard assessment. Modern surveys integrate geology, geophysics, geochemistry, and numerical modeling to understand complex subsurface flow systems.	Well log analysis is the systematic examination of measurements recorded by instruments lowered into a borehole to characterize subsurface lithology, fluid content, and petrophysical properties. Originating in the 1940s, this method has become indispensable for petroleum exploration, groundwater assessment, and engineering geology. Well logs provide direct depth-correlated data that anchor interpretation of seismic surveys and constrain reservoir models.
