| Resumé≠ | Geophysical inversion is the process of using observed geophysical data to estimate subsurface properties and structures. Formalized by Tikhonov (1963) and expanded by Tarantola (1987), this mathematical framework solves the inverse problem: given measurements (gravity, magnetics, seismic, electrical), what subsurface model produced them? Inversion is central to all quantitative geophysics and enables extraction of detailed subsurface information from surface or borehole measurements. | 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. |
