Q2: A well is producing from a saturated oil reservoir with a reservoir pressure of 2000 psi. A resent flowing test of the well indicated a producing rate of 100 bopd with a flowing bottomhole pressure of 1500 psi .Assuming the reservoir pressure will decline by 500 psi in two years, what the rate will the well produce with 1000 psi bottomhole pressure?
