7. A cylindrical core, of 2.5 cm in diameter and 5 cm in length, has a porosity of 23%. The retort distillation method was used to find the fluid saturation inside the core. Using this method, 3.2 cm3 of water and 1.9 cm3 of oil were extracted from the core. a. What are the fluid saturations in the core? b. If the formation factor is given by F = 1.09-2, the resistivity index is given by I r = Sw -2, and the water resistivity is 7.5 Q.cm, calculate the true resistivity of the core which we would expect to have it measured before fluid extraction.
