The following data pertain to a carbonate formation: forma- tion thickness =15 ft; formation water salinity=95,000 ppm; formation temperature=200°F; and cementation factor=2.2. The vertical resistivity profile of the formation is shown by Fig. 1.33. a. If Zone B is water-bearing, estimate its porosity. 5. If Zone A is an oil zone, estimate the oil saturation. c. Using qualitative and quantitative reasoning, give a com- plete explanation of the relatively high resistivity displayed by Zone C of the formation. ||
