Question A well produces oil at a rate of 108 STB/D with a bottomhole flowing pressure of 1980 psia. Surface samples were collected and sent to a PVT laboratory, which determined the bubble-point pressure of the recombined reservoir fluid to be 1825 psia at a temperature of 195°F. An initial reservoir pressure of 3620 psia was recorded during the 48-hour buildup flow test. Determine: a) The undersaturated productivity index that is valid if the flowing bottomhole pressure is greater than the bubble point. b) The oil rate if the bottomhole flowing pressure is held at the bubble point to avoid gas blockage in the near-wellbore region. c) Using Equation 2, calculate the maximum oil rate that can be expected from the well. d) Calculate and plot the IPR for the entire range of the wellbore flowing pressures, both above and below the bubble point.

A well produces oil at a rate of 108 STB/D with a bottomhole flowing pressure of 1980 psia.
Surface samples were collected and sent to a PVT laboratory, which determined the bubble-point
pressure of the recombined reservoir fluid to be 1825 psia at a temperature of 195°F. An initial
reservoir pressure of 3620 psia was recorded during the 48-hour buildup flow test. Determine:
a) The undersaturated productivity index that is valid if the flowing bottomhole pressure is
greater than the bubble point.
b) The oil rate if the bottomhole flowing pressure is held at the bubble point to avoid gas
blockage in the near-wellbore region.
c) Using Equation 2, calculate the maximum oil rate that can be expected from the well.
d) Calculate and plot the IPR for the entire range of the wellbore flowing pressures, both
above and below the bubble point.
