Problem 2. (3!) points) You are hired by an oil company to estimate the maximum oil and gas saturations [5?\" and Sitar} of a reservoir with the openhole log shown in Figure 2. From the log header. we know that the surface temperature is T2F, the geothermal gradient is 1.15 \"F me It . and the resistivity of mud filtrate measured at the surface conditions is 1 m. 1} 2} 3} 4} 5} 5} Identify the hydrocarbon reservoir and gas-oil contact on the log. Identify the aquifer and water-oil contact on the log. Calculate the average resistivity of water at the bottom of the hydrocarbon reservoir using SP log. The formation resistivity factor of this interval can be modeled by F = i. Calculate the value of a by using the log data. Calculate average R0 for the hydrocarbon reservoir. Calculate 531\" and ngx by using the data obtained in the previous steps and if saturation exponent1 n = 2. 2. 500 _RHGAG/C37...-. 3.000 0. 6000 0.0 RFA (OHMM> DPHIC S.
