Ключевой момент (керн через 1.5 дюйма сопоставляется с каротажем)

Data Description: In this study, the well log data and
corresponding core data of three wells were employed for
training and examining the validation of the proposed
method. Firstly, the data sets were processed and bad-
hole intervals, in which the derivation between the caliper
and bit-size logs is larger than 1.5 inch, were removed. To
ensure the correct reading of well-log data against core
permeability, a depth-matching procedure was carried
out.Normalization of data is another task, which could
be done for better prediction of outputs. In the training
data, permeability range changes from 0.007 to 271 md.

This wide range causes low performance of the
model in permeability prediction; therefore, the
normalized data have been used to enhance the
performance of prediction. A total of 301 core samples
were available for this research, among them 218 samples
were from Well A and B (train wells) and 83 samples were
used for validating purposes. The train and test wells
should be located in a suitable distance from each
other. In a suitable distance, the geological and
petrophysical rock properties that affect the reservoir
characteristics are consistent. The available well log data
for this study were gamma ray (GR), sonic (DT), bulk
density (RHOB), deep laterolog (LLD), photo electric
factor (PEFZ) and corrected neutron porosity (NPHI).
