You are to analyze two core samples from the same reservoir. The core samples are taken from the same well from the same formation. Both of them have the same size. (6cm in length and 1in diamater ). One of the samples is dried and cleaned for porosity analysis. The dry weight of the sample is 67.4g. When saturated with pure water, density of which is 0.99g/cm3 at the laboratory conditions, the weight becomes 72.8g. The weight of the other core that is kept at original saturations is 72.3g. You are given the information that there is no free gas in the system. You need to find the oil and water saturations of the core sample. The density of the reservoir brine is 1.1g/cm3 and the density of the oil is 0.875g/cm3 .
