Claim 0:
1. A geological exploration method comprising:
obtaining measurements and calculating property values associated with depth values along boreholes in an area of interest to generate log data including plural curves;
detecting anomalies along at least one curve among the plural curves, the at least one curve corresponding to a first borehole among of the boreholes;
training 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;
blending the synthetic curve into the at least one curve to obtain a blended curve;
obtaining seismic data for the area of interest; and
applying an inversion method to the seismic data to generate a three-dimensional image of underground formation in the area of interest, the inversion method being calibrated using the blended curve, the three-dimensional image being usable to plan hydrocarbon extraction.
