Prospecting for oil and gas using exploration seismology, a geophysical method of determining geologic structure by means of prospector-induced elastic waves. By studying body waves such as compressional and shear waves propagating through the Earth's interior, the constituent and elastic properties of its solid and liquid core, its solid mantle, and its thin crust are defined.
