3.A core sample is saturated with an oil (po = 35°API), gas and water. The initial weight of the sample is 224.14 g. After the gas is displaced by water (pw = 1 g/cm'), the weight is increased to 225.90 g. The sample is the placed in a Soxhlet distillation apparatus, and 4.4 cm' water is extracted. After drying the core sample, the weight is now 209.75 g. The sample bulk volume, 95 cm3 is measured in a mercury pycnometer. Find the porosity, water saturation, oil saturation, gas saturation and lithology of the core sample.
