A miscellaneous gas well were tested using a three-point conventional deliverability test. Data recorded during the test are given below: Use Simplified back-pressure equation and answer the following: A. Generate the current IPR and B. Generate the future IPR when 80% of reservoir pressure is remain, Specific gravity of gas =0.70 and reservoir temperature = 200F, assume constant gas viscosity is equal to 0.016 C. Determine the AOF for both conditions of reservoir pressure, discuss your results
