Claim 14:
15. An underground exploration apparatus comprising:
an interface configured to obtain measurements and to calculate property values associated with depth values along boreholes in an area of interest to generate log data including plural curves, and to obtain seismic data for the area of interest; and
a data processing module connected to the interface, including at least one processor and configured
to detect anomalies along at least one curve among the plural curves, the at least one curve corresponding to a first borehole among of the boreholes,
to train a machine learning regressor using the at least one curve without anomaly values and/or another curve among the plural curves, the other curve corresponding to a second borehole among the boreholes, the second borehole being similar with the first borehole, to predict a synthetic curve corresponding to the at least one curve,
to blend the synthetic curve into the at least one curve to obtain a blended curve, and
to apply an inversion method to the seismic data to generate a three-dimensional image of underground formation in the area of interest, wherein the inversion method is calibrated using the blended curve, the three-dimensional image being usable to plan hydrocarbon extraction.
