Reevaluate of Gas lift system for a heavy oil well case study Fula north

Abstract

Gas lift is one of the best method of artificial lift which achieves the economic goals which achieve the country and company policies. The aim of the study is minimizing the viscosity of the oil by reaching the dilution stage for the well fula north 66 that located in Block 6,by using PIPESIM software to design the gas lift model. The data has been collected and the model has been designed , several injection rates are entered to accomplish the dilution stage (1, 1.5 ,2 ,2.5 ,3,4,5 mmscf/day) and the highest viscosity diminution is happened with the injection rate (3 mmscf/day) as the suitable one ,therefore, the production rate will increase as a result of viscosity diminution. The study shows that the viscosity has been decreased from (3863.63 cp) to (1700 cp) which means the study is successful.
