| Zusammenfassung≠ | Petrographic analysis is the microscopic examination of rock thin sections to determine mineral composition, grain size, texture, and diagenetic alteration. Pioneered by Sorby in 1858, this method remains the gold standard for understanding lithology and has evolved to include quantitative image analysis and cathodoluminescence. Petrographic data anchor well-log interpretation, validate seismic velocity models, and constrain paleoenvironmental and diagenetic histories. | 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. |
