Solutions

1. Determine the specific gravity of the oil:

SG, = 141.5 - - 141e5 -0.763
131.5 + API 131.5 + 54

2. Find the weight associated with 1 bbl of stock-tank liquid

m = SG,(350)( l+$0R)+SG0(350)( 1 + WoR WOR )+(0.0764)(GLR)(!3Gg)

1 1
= 0.763(350)(%) + 0.763(S50)(lco) +0.0764(3393)(0.752)
= 462 IWstb of oil

3. Determine the specific weight of the liquid phase:
