  14. Differential Liberation Expansion Gravity of residual oil = 35.1 °API @ 60 °F 1 Volume of gas at the standard conditions per volume of residual oil. 2 Volume of oil at indicated pressure and temperature per volume of oil at the standard conditions. 3 Volume of oil plus liberated gas at indicated pressure and temperature per volume of residual oil at the standard conditions. 4 Volume of gas at indicated pressure and temperature per volume at the standard conditions. PETE 216

  15. Multistage Separation Test PETE 216

  16. Multistage Separation Test 1 GOR per barrel of oil at indicated pressure and temperature. 2 GOR per barrel of stock-tank oil at 60 °F. 3 FVF per barrel of stock-tank oil at 60 °F. 4 Separator oil volume factor per barrel of stock-tank oil at 60 °F. PETE 216
