Abstract:
This paper presents results of a study conducted to evaluate changes in oil properties of an oilfield due to gas injection and their effects on production from this field while under gas injection. In this work, effects of gas injection on reservoir fluid phase behavior of a fractured oil reservoir have been investigated. For this purpose, first, the properties of primary reservoir fluid have been studied. Then, by using software, a suitable equation of state for prediction the behavior of reservoir fluid was selected. Then, properties of current reservoir fluid which were achieved by PVT tests have been studied. Phase behavior of current reservoir fluid was compared with phase behavior of primary reservoir fluid. It was found that phase behavior of reservoir fluid has been changed due to gas injection into this reservoir. After evaluating oil properties of this field, we describe how these properties affect reservoir quality and EOR strategy.
