... in the carbonate formation porosity measurements by conventional and NMR logging methods compared to stress core porosity by graphical means. Results of this study showed that a clear criterion to divide the formations into dolomitic and clean formation (pure limestone) should be established to get more accurate...

... hole logs data. The developed NN models use the NMR T2 pin values, and density and resistivity logs to predict porosity, and permeability for two test wells. The NN trained models displayed good correlation with core porosity and permeability values, and with the NMR derived porosity and permeability...
