Summary:
Seismic inversion is a geophysical workflow that is routinely used by geoscientists in many basins around the world in Exploration & Production companies. The higher quality well logs (especially p- and s-wave sonic data) can be obtained for the inversion, the better the results. Oil and gas companies compile large rock property databases to aid inversion in exploration, when only few or no wells are available to support a new hydrocarbon play in an undrilled geological setting. The paper describes how seismic inversion was applied in brownfield exploration in the West Siberian Basin. Here, the operator tried to stop or better reverse the oil production decline.
