Claim 9:
10. A permeability estimating apparatus, comprising:
a processor configured
to select training data and test data from well logs for which core-analysis-based permeability values are available,
to train two regression algorithms to generate a depth blended model for estimating permeability values, based on well logs included the training data with their corresponding core-analysis-based permeability values being used for calibrating the depth blended model, the depth blended model outputting first values obtained by applying a first regression algorithm among the two regression algorithms when the first values are positive, and outputting second permeability values obtained by applying a second regression algorithm among the two regression algorithms otherwise,
selectively adjusting algorithm parameters of the two regression algorithms depending on an overall consistency check of the first values and the second values obtained for the test data; and
to apply the depth blended model to the well logs for which respective core-analysis-based permeability values are not available for obtaining model-estimated permeability values; and

a communication interface connected to the processor and configured to exchange data with other devices and/or enable interaction with a user,
wherein the model-estimated permeability values are used to plan hydrocarbon production, and the depth blended model selectively outputs values obtained via at least two of the regression algorithms.
