ABSTRACT:
Methods and apparatus are provided to extract oil and brine fluids from a representative porous sample. The petrophysical properties of these extracted oil and brine fluids may be determined by conventional or other testing methods. The oil fluids and brine fluids are separated from each other by separate distillation and condensation, and by removing the solvent from the oil fluids. The amounts of oil and brine fluids from the sample may then be separately determined. The apparatus uses a desiccant container at the top of a soxhlet tower beneath the cold finger (which condenses the solvent gases that have been evaporated) in a pressure soxhlet extractor to capture any brine or water and thus, separate the brine or water from the oil and/or solvent which remain in the soxhlet extraction chamber at the bottom of the soxhlet tower.
