Tiivistelmä	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.	Seismic reflection interpretation is the process of extracting meaningful geological information from seismic survey data, which is collected by recording elastic waves reflected from rock layers beneath the surface. Developed and systematized in the mid-20th century, this method is foundational in petroleum exploration and engineering geology. It enables geoscientists to image subsurface structures, identify hydrocarbon prospects, and assess hazards without drilling.
