Abstract
Abstract Conventional core analysis procedures were investigated to validate data quality and accuracy. In this paper, 23 core samples from wells Q (14 carbonate samples) and N (9 sandstone samples) were tested in the laboratory. The tests include grain density, porosity, and air and brine permeabilities. Factors investigated in this study are:∘Effect of equipment calibration on grain density and porosity measurements,∘Effect of drying time on grain density and porosity measurements,∘Effect of sleeve confining pressure on gas permeability measurement, and∘Comparison between gas and liquid permeabilities. Understanding data acquisition procedures and limitations is very important in core analysis. Therefore, data accuracy in laboratory measurements must be considered. Based on this study, best practices of performing conventional core analysis are recommended.
