High Quality Content by WIKIPEDIA articles! Seismic inversion is the process of transforming seismic reflection data into a quantitative rock property description of a reservoir. Seismic inversion may be pre-or post-stack, deterministic, stochastic or geostatistical, and typically includes other reservoir measurements such as well logs and cores. Seismic surveys are routinely performed to gather information about the geology of an oil or gas field. These surveys record sound waves that have traveled through the layers of rock and fluid in the earth. The amplitude and frequency of these sound waves can be estimated so that any side-lobe and tuning effects introduced by the wavelet can be removed.
