Claim 18:
19. A non-transitory computer-readable medium storing instructions that, when executed by at least one processor, cause the at least one processor to perform operations comprising:
receiving, from a first seismometer, seismic data for a first region of a subterranean formation, seismic data representing a propagation of seismic waves within the first region;
receiving, from a well log instrument, well log data of one or more wells located at the first region;
determining, based on the received seismic data of the first region, one or more relative layer attributes of the first region, the one or more relative layer attributes representing one or more relative elastic properties of one or more formation layers of the first region;
determining, based on the one or more relative layer attributes of the first region, one or more first input values for a machine learning model;
determining, based on the received well log data, one or more second input values for the machine learning model;
generating, based on the one or more first input values and the one or more second input values, by executing the machine learning model, a relative low frequency model for the first region;
extrapolating, by executing the machine learning model, the relative low frequency model to a second region of the subterranean formation, the second region being distinct from the first region;
updating, based on the extrapolating, by executing the machine learning model, the relative low frequency model to span the first region and the second region;
scaling, based on the well log data of the first region, the relative low frequency model;
generating, based on the scaling, a scaled low frequency model representing one or more scaled elastic properties of the one or more formation layers of the first region and one or more formation layers of the second region; and
performing, based on the scaled low frequency model, seismic waveform inversion.
