Resistivity, sonic, and density logs can be used to construct [[synthetic seismogram]]s which, in turn, can be used to calibrate and refine seismic profiles. Hence, there is a tie-in with geophysical [[modeling]] (directly in the case of sonic–density transforms, indirectly in the case of resistivity transforms). | Resistivity, sonic, and density logs can be used to construct [[synthetic seismogram]]s which, in turn, can be used to calibrate and refine seismic profiles.
