24. Figure below is for one dimensional linear flooding of a specific reservoir. The only difference in the cases is the ratio of injected water to oil viscosities as shown in the figure. According to this figure: (6) a) Which case has higher front velocity? Case 1) Case 2, Case 3 b) Which case has the earliest breakthrough time C Case 1 Case 2, Case 3 c) In which case the total water injected at breakthrough is higher? Case 1, Case 2. Case 3. d) In which case the microscopic displacement efficiency is higher? Case 1, Case 2, Case 3
