Seismic Inversion Methods: A Practical Approach / Методы сейсмической инверсии: практический подход

Seismic inversion methods in geophysics is a technique used to transform seismic reflection data into quantitative subsurface rock properties. It is methods to integrate seismic reflection data along with well log data to extract a variety of petrophysical parameters. Geophysicists regularly perform seismic surveys to collect subsurface geological information in the exploration project. Such surveys record sound waves that have passed through the earth’s layers of rock and fluid in the form of amplitude and time. The recorded seismic data can be interpreted on its own but this does not provide sufficient information of the subsurface and can be inaccurate under certain circumstances. Because of its efficiency and quality, most oil and gas companies now using seismic inversion methods to increase data resolution and reliability and improve rock properties estimation including porosity and net pay. In this chapter, the basics of forward modeling, convolution model, seismic inversions and their kinds are discussed.<...>
