A clean sandstone core sample with diameter of 3.8 cm and length of 5.6 cm is saturated with a brine. The core was desaturated in several steps, and the resistance was measured at each saturation. The results are as follows: Water Saturation (Fraction) Resistance (kS) 1.000 1.302 0.900 1.695 0.800 2.283 0.730 2.878 0.640 3.775 0.560 5.637 0.480 7.838 0.375 13.175 0.350 17.050 0.300 26 Brine resistivity= 0.74 2m Archie coefficient 1.03 Cementation factor= 2.2147 (1) Estimate the rock porosity. (2) Determine the saturation exponent. (3) Estimate the amount of oil and brine (in cc) in the core sample when resistivity index is 5. All steps of the calculations should be shown.
A clay layer 5 m thick has double drainage. It was consolidated under a load of 127.5 kN/m2. The load is increased to 197.5 kN/m2. The coefficient of volume compressibility is 5.79 x 10^-4 m2/Kn and value of k = 1.6 x 10^-8 m/min. If the test sample is 2 cm thick and attains 100% consolidation in 24 hours, what is the time in days taken for 100% consolidation in the actual layer? a. 62,500 b. 60,000 c. 65,000 d.67,500

There are 2 samples of granite rock from similar sampling site. However, its dimension height and diameter are different, i.e. for sample A is 104mm : 52mm (height : diameter) and sample B 52mm : 52mm. Between sample A and B, which is expected give a higher rock strength. Justify your answer?
