概要	Geomechanical modeling is the numerical simulation of stress and deformation in rock masses, integrating rock properties, pressure conditions, and geometric constraints. Rooted in classical mechanics (Coulomb, Mohr) but modernized by finite element and finite difference methods, this approach is essential for well integrity assessment, reservoir compaction prediction, and stability evaluation of slopes and excavations. Models link subsurface geology to rock mechanical behavior.	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.
