Abstract
Embodiments of the subject technology provide for predicting seismic impedance. The subject technology generates a corridor stack based on vertical seismic profile (VSP) data of a wellbore in a subterranean formation. The subject technology generates an initial estimate of a velocity model for the subterranean formation below the wellbore. The subject technology generating a density model for the subterranean formation below the wellbore based on information from nearby wells. The subject technology inverts, based on a global inversion algorithm and the initial estimate of the velocity model, the generated corridor stack to determine a set of velocity models. The subject technology generates impedance models in a depth domain based on the generated density model and the set of velocity models. Further, the subject technology stores the generated impedance models.
