- Abstract:
- Water-cut crude oil has a great influence on crude oil trade measurement. The accuracy of oil volume in water-cut crude oil is closely related to the interests of both buyers and sellers. In this paper, the computation procedure based on API20.1 is analyzed in order to assure one more accurate metering method for the volume of oil. This paper uses the data from one metering skid to discuss the influence effect of different factors involved in the computation procedure. The analyzed factors include the density of crude oil/water mixture at metering conditions, volume fraction of water in the crude oil/water mixture at metering conditions, shrinkage correction factor of crude oil, and temperature at metering conditions. Analysis results show that the factors did not have an equal effect on the calculated volume of oil. The density has the least influence range on the oil volume of water-cut crude oil. The temperature is the least sensitive factor. The volume fraction and shrinkage correction factor need to pay more attention to because the calculated volume of oil is highly sensitive to these two factors.
