Prediction Of Stability Of The Asphaltene Fraction In Crudes Del Campo Pacoa (Ecuador)

Abstract

The present study will evaluate the concentration and stability of the asphaltenes of 5 crudes obtained from the different producing levels of the Pacoa field as well as the mixture of all of them in the central tank at static surface conditions (1 atm) and 60ºF from the methods of "Stability index (IE)", "Colloidal stability index (IEC)",  "Stankiewiez stability criterion (CES)", culminated with the "Sepulveda stability criterion (ACC: qualitative and quantitative analysis)" and La Mancha method.
