Claim 1:
2. The method of claim 1, further comprising:
validating the model, wherein validating the model includes:
inputting into the model, as the three main inputs, the neutron log data, total gamma ray log data, and density log data measured for a test well among the wells, and
predicting, by the model based on the three main inputs, synthetic spectral gamma ray log data representing levels of potassium, thorium, and uranium, respectively, for the test well;
comparing the synthetic spectral gamma ray log data for the test well to actual spectral gamma ray log data measured for the test well, and
determining, based on the comparison, whether the synthetic spectral gamma ray log data matches the actual spectral gamma ray log data to a prescribed degree of accuracy, and
in response to determining that the synthetic spectral gamma ray log data for the test well matches the actual spectral gamma ray log data for the test well to the prescribed degree of accuracy, validating the model, and
in response to determining that the synthetic spectral gamma ray log data matches the actual spectral gamma ray log data to the prescribed degree of accuracy, repeating the filtering, training and validating step until the synthetic spectral gamma ray log data for the test well matches the actual spectral gamma ray log data for the test well to the prescribed degree of accuracy.
