Abstract
This research contains about the search for petrophysical parameters in digital Core samples as well as modelling in the form of 3D from synthesis sandstone samples that have a pixel size of 5123, which aims to determine porosity value, absolute & relative permeability (krw), krw vs Sw result curve, for the calculation method used is the Corey-Exponent method, as well as Core-logs. The results of this study show similarities in simulation and calculation results, as well as by comparing the results of simulations with existing laboratory results resulting in a value close to the laboratory results, the difference in results can be caused by various things both due to human factors and factors of the application, so that a good ability is needed in the application to minimize errors that occur. It is also worth noting that the computer device used also affects how the application runs, so it is better if the computer used has above average specifications.
Keywords: Digital Core, Porosity, Relative Permeability, Sandstone, Simulation.
