Fig. 1.31-Unit block of porous medium of Problem 1.2 1.2 A rock is made up of several blocks, as shown in Fig. 1.31. The unit block is a rectangular prism of nonporous, noncon- ductor material of length L and square cross section with side length d. A cylindrical hole of diameter d is drilled through the block and filled with brine. a. Determine the formation resistivity factor of this rock block. b. What relationship exists between the formation factor, F...
3. A 3.33g rock sample containing iron was dissolved in sulfuric acid with the formation of a solution of FeSO4. This solution of FeSO4 was then titrated with 16.9mL of a 0.250M K2Cr207 solution. + K2SO4 (aq) 6FESO4 (aq) + K2Cr2O7 (aq) + 7H2SO4 (aq) 3Fe2(SO4)3 (aq) + Cr2(SO4)3 (aq)+7H20 (D) Calculate the percentage of iron (Fe) in the 3.33g rock sample.
#2. Calculate the porosity of the core sample and the density of the matrix material from the following data: Weight of cleaned and dried sample=37.25g Weight of sample, saturated with oil =41.39g Weight of saturated sample, immersed in saturating oil =25.65g Density of oil = 41 39 0.80 g/cm Is your value of calculated porosity total or effective? Briefly explain why or why not. What is the probable lithology of the core sample?
A 1.130 g sample of limestone rock is pulverized and then treated with 30.00 mL of 1.035 M HCl solution. The excess acid then requires 11.56 mL of 1.010 M NaOH for neutralization. Calculate the percent by mass of calcium carbonate in the rock, assuming that it is the only substance reacting with the HCl solution. Express your answer using four significant figures.
