2. The oil sands of Alberta, Canada contain commercially viable quantities of oil. The average properties of the oil sands are as follows: - Initial bulk density = 2.06 Mg/m3 - Initial porosity = 0.35 - Oil saturation = 70% of pore volume - Specific gravity of soil solids = 2.68 - Specific gravity of oil = 0.86 - Note: assume pore contain only oil and water (no air)
