Exact excerpt

This study uses data from 12 cored wells in the Chang 8 Member, Jiyuan Oilfield (western Ordos Basin) to develop a permeability-driven integrated workflow for reservoir evaluation. We first build an SE-ResNet18 model with one-dimensional convolution and residual learning to capture vertical continuity in well logs, achieving R² = 0.86 and RMSE = 0.287 mD for permeability regression.
