Question 1 a b C d CLO CLOI CLOI CLOI CLOI Marks 7.5 7 7.5 An oil production well was tested at multiple rates and the result is as in Table 1. The reservoir pressure from the pressure build-up test is recorded at 1200 psig. Table 1: Production test data Oil flow rate (BOPD) Test 1 2 3 4 70 147 280 292 Flowing Bottom hole pressure (psig) 1147 1023 612 530 Base on the test data, determine the following. a) The flow coefficient, flow exponent, and the inflow performance equation. b) Calculate and plot the IPR (inflow performance relationship). c) Assuming that the flow exponent remained constant, calculate and plot the future IPR when the reservoir pressure declines to 900 psig. d) From the plots, how many percent of well capacity reduction is expected due to the pressure decline
