Bandlimited seismic inversion free
Seismic inversion is a technique that has been in use by geophysicists for over forty years. Early inversion techniques transformed the seismic data into Pimpedance (the product of density and Pwave velocity), from which we were able to make predictions about lithology and porosity.
How can the answer be improved?

Seismic inversion, in geophysics, is the process of transforming seismic reflection data into a quantitative rockproperty description of a reservoir. Seismic inversion may be pre or poststack, deterministic, random or geostatistical; it typically includes other reservoir measurements such as
Seismic inversion. The object of seismic inversion is to convert the seismic interpreter's view of the earth reflections as a function of time to the geologist's view of the earth velocity as a function of depth. This is not as easy as it may seem. The reason for this is that seismic data measurements are taken at the earth's surface
inversion in red are compared with the bandlimited log data in black. Also shown are the seismic traces at four angles, the inversion synthetics and res iduals. The inversion that produced the results in the upper plot only differs from the lower plot inversion through the strength of the rock physics constraint applied.
Seismic Inversion for Reservoir Characterization. CGG GeoConsulting utilizes a variety of different seismic inversion techniques. The appropriate technique is determined by the complexity of the geologic conditions, the customers reservoir characterization goals and the data available.
