I need the problem 3 in Handwritten
Problem 3:
For a sandstone reservoir, calculate the water saturation if the porosity (Ø) is (20 %), the resistivity
of the formation water (Rw) is (0.09) and the true resistivity (R.) is (15)?
Problem 4:
Calculate the water saturation for a sandstone reservoir if the porosity (Ø) is (10 %), resistivity of
formation water is (Rw = 0.02 Om) and the resistivity of the formation (Rt= 20 Qm)?
