Comparison of Log and Empirical High Function Saturation and It’s Effect on Volumetric Calculations
Downloads
This paper discusses the comparison of the Saturation Height Function between the saturation calculation method based on log data using various equations such as Archie, Indonesia and Dual Water with the empirical method which is popularly used in the oil and gas industry, namely the Cuddy method. The advantages and disadvantages of each method will be discussed. Each method of calculating saturation with log data is compared with the Cuddy method to get an idea of which geological conditions are most suitable for the Cuddy method. This study was carried out by modeling the well oil saturation height profile from an Oligocene well from the North West Java Basin of Indonesia. This well was chosen because it did not have complete data, only a series of Electrical logs and no conventional core and SCAL data. Apart from comparing each method on the well, this paper also compares volumetric calculations based on the resulting oil saturation height profile model.By comparing the results of each volumetric calculation, we can find out which method gives better results so that without core data we can still make STOIIP predictions quite validly.
