Petrographic and Petrophysical Characterization of Sandstones from Rio Bonito Formation, Paraná Basin (Southern Brazil).

This study focuses on the laboratory-scale petrophysical characterization of sandstones from the Rio Bonito Formation (Lower Permian), Paraná Basin, carried out from drill core samples from well PN-14-SC.02 obtained by CPRM-Brazilian Geological Service in the 1980s on the eastern edge of the Basin. This study includes integrating experimental data from routine petrophysics, sedimentary petrography, and nuclear magnetic resonance (NMR) obtained from 6 samples arranged in the normal direction of the stratification, present between 40 and 200 m deep.
