Question 1: An oil well produced 500 bbl/d with a flowing BHP of 2500 psi. If the average reservoir pressure is 3000 psi find the maximum possible rate from the well. Also find the production rate when the producing pressure dropped to 1200 psi. Also find the maximum rate if a linear relationship is assumed. The bubble point pressure is 3000 psi. Question 2: A well is producing from a reservoir having an average reservoir pressure of 2085 psig. A stabilized production test on the well resulted in a producing rate of 282 STB/day when the flowing bottom-hole pressure was 1765 psig. The bubble point pressure is 2100 psig. Using constant PI, Vogel’s, and Fetkovich’s equations, calculate: i) the producing rate if P wf is reduced to zero ii) the producing rate if P wf is reduced to 1485 psig iii) the bottom-hole pressure necessary to obtain an inflow rate of 400 STB/day iv) the complete IPR Question 3: The following data pertain to an under-saturated reservoir: a) Generate an IPR. If the well is retested and b) Generate an IPR using this test data. Question 4: A flow-after-flow test was conducted on a well producing from a reservoir in which . The test results were: q o (STB/day) P wf (psia) 263 3170 383 2897
