PGE 312 – Spring 2004 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. 1. ( 15 points ) Sketch fully labeled diagrams to show how the following properties of an undersaturated reservoir oil will vary with the reservoir pressure as the reservoir is depleted from the initial reservoir pressure (P i ) to 0 psig at the fixed reservoir temperature. Please mark P i , P b and 0 psig on the pressure axis of your sketch, where P b is the bubble point pressure of the oil. Be sure to state the units of what is being sketched. a) Oil formation volume factor. b) Solution gas oil ratio. c) Oil viscosity. 2. ( 85 points ) Attachment 1 shows part of the report of a laboratory reservoir fluid study for an undersaturated black oil reservoir (Low shrinkage oil). Two-stage separation is used in this field with the separator pressures and temperatures as follows: Stage 1:
