As just mentioned, seismic data give us a “fuzzy” picture of the subsurface over a large area, whereas wells give us detailed geological information at a few points. This suggests a general approach to the seismic inversion method, as shown in [[:file:seismic-inversion_fig1.png|Figure 1]]. On the left side of this flowchart, the input is our best reflectivity estimate from the seismic data. On the right side, we introduce geological constraints taken from a sonic log or seismic velocity information and produce a forward model. We then combine the information from the seismic data with controlling information from the seismic model and produce a final inversion result. | As just mentioned, seismic data give us a “fuzzy” picture of the subsurface over a large area, whereas wells give us detailed geological information at a few points.
