a. Given the following water oil relative permeability curves,you are asked to explain how we can reach the conclusion that almost 10% percent of the pore space contributes noting to the permeability and that approximately %15 percent of the pore space contribute 40% percent of the permeability. (Hint the base permeability in the figure is absolute permeability.) 10 Water 02 04 10 Water saturation, fraction of pore space State if the following statements are correct or false and tell why if you decide that it is false: b. The flow of natural gas through a rectangular sand body is always linear, compressible and unsteady state flow. c. Expressing the MBE in a straight line form is advantageous because it allows considering all data points simultaneously and hence avoids random errors in individual point calculations d. Injection of water into a volumetric reservoir is an immiscible displacement, but relative pemeability has no role in the displacement. e. Muskat, Shiulteous and Tamer methods are the well known methods of estimating oil recovery by intemal gas drive. They all consider that the free gas in the reservoir is immobile. f. The purpose of history matching is basically to tune the parameters of our model so that we can use it confidently for future performance predictions Wi Relative premeability.
