PGE 312 – FALL 2003 Physical and Chemical Behavior of Petroleum Fluids I Test #3, 50 Minutes Closed Book Note: It will be in your best interest to attempt all the questions. Please budget your time accordingly. Attachment 1 shows part of the report of a laboratory reservoir fluid study for an undersaturated black oil reservoir. The initial reservoir pressure is 4500 psig. A subsurface sample was used for the fluid study. Three-stage separation is used in this field with the separator pressures and temperatures as follows: Stage 1: P = 70 psig, T = 130 ° F Stage 2: P = 15 psig, T = 73 ° F Stage 3: P = 0 psig, T = 73 ° F All the PVT properties for this reservoir are based on these 3-stage separator conditions. Please note that you will not get any credit if you perform the PVT calculations using separator conditions other than those given above. 1. ( 5 points ) What is the bubble point pressure of this oil at reservoir temperature in psig? 2.
