...Data-Driven Methodology This section outlines the process of developing machine learning (ML) models for predicting three key targets from open-hole logs: bulk density (RHOB), neutron porosity (NPHI), and compressional sonic travel time (DTC). Figure 1 present the flowchart to conduct...

... desired diameter. In this research, we acquired approximately thirty virtual plug samples (1-inch diameter) from 15-meter sandstone cores. Porosity of the virtual plugs was calculated through the correlation between bulk density and the CT numbers, and these values were compared with laboratory-measured...
