Unformatted text preview: HOMEWORK# 3 SOLUTION KEY 5-1. The initial and final reservoir conditions and the separatoe conditions are plotted on figure 2-37 (shown above). a. The reservoir fluid would be classified as dry gas . No liquid will be formed either in the reservoir or on the surface. b. The reservoir fluid would be classified as wet gas . It will exist solely as gas in the reservoir throughout the reduction of pressure, however at the separator conditions lie within the phase envelope, which will cause some liquid to form. c. The reservoir fluid would be classified as retrograde gas . As the pressure is reduced it will exhibit a dew point at the reservoir temperature. d. The reservoir fluid would be classified as volatile oi l. The critical point of the fluid is close to the initial reservoir conditions. e. The reservoir fluid would be classified as Black oil . 5-2. For the first reservoir, gas oil ratio = 50,000scf/ 10 STB = 5,000 scf/ STB The reservoir fluid is probably retrograde gas, since retrograde gas has a GOR over 3300 scf/ STB. For the second reservoir, the GOR =...
