Abstract
Methods and a system for determining a composition of a fluid from a reservoir are provided. An exemplary method includes depressurizing a single-phase fluid to atmospheric pressure to separate a gas phase from a liquid phase, recording the volume of the gas phase, determining the weight of the liquid phase, and determining an atmospheric gas-oil ratio (GOR) from the volume of the gas phase and the weight of the liquid phase. The method also includes determining the composition of the gas phase to C9+, measuring the density of the liquid phase, determining the molecular weight of the liquid phase, and determining the composition of the liquid phase to C45+. The total hydrocarbon composition of the fluid is calculated from the amount of the gas phase, the amount of the liquid phase, the composition of gas phase, the composition liquid phase, and the atmospheric GOR.
