摘要：
A statistical correlation to provide reasonable estimates of crude oils SARA compositions,(saturates, aromatics, resins, asphaltenes) from bubblepoint pressure and light-ends compositional data is presented. In developing the correlation, we collected experimental SARA compositions of 341 crude oils of different origin. The most-probable SARA compositions are then obtained by seeking the maximum probability according to its oil type, in line with the measured values of bubblepoint pressures. Results show that the proposed method is simple and provides reasonable values of SARA compositions of an oil in cases in which only the light-ends compositions and a few bubblepoint pressures are available.
