Abstract:
Oil viscosity is veryimportant property in oil industry, it’s very important in the designing of production equipment, testing wells, EOR methods selection and pipelines.
And for that a new correlation has been developed to measure viscosity at different temperatures for a set of heavy oils from the Sudanese oil fields (FNE and FN) using least approximation method (logarithmic form) using excel , covering a viscosity range from 3000 to 39412 mPa.s. A good relationship emerges between temperature and viscosity for a corresponding viscosity temperature correlation with a high confident was obtained for every oil sample. Detailed investigations showed that (viscosity values at temperature T°C) shows a strong function of (viscosity value at 29°C).
Therefore, this correlation is used for predicting oil viscosity with only two input parameters: temperature and viscosity at 29°C and it can be used to provide an alternative method to predict the viscosity for heavy oils in Sudanese oil fields.
