A 1.0” diameter by 1.5” long core was cleaned. The measured dry and saturated densities are 2.160 gm/cc and 2.311 gm/cc. The measured porosity is 15.85%. In the process, the following fluid volumes were removed: 1.84 ml of water and 1.22 ml of oil. The oil has a measured density of 0.77 gm/cc and based on salinity measurements, the water corresponds to a brine having a density of 1.05 gm/cc. Calculate fluid saturations and determine the lithology.
