Study correlates asphaltene precipitation to reservoir pressure

08/02/2004
Modeling of asphaltene precipitation in Bangestan reservoir of Kupal field in southwest Iran estimated the pressure at which asphaltenes precipitate under reservoir conditions. The reservoir-engineering department has plans to inject gas into the reservoir to increase the reservoir pressure above this estimated precipitation pressure.The modeling technique assumed the precipitated asphaltene was a pure dense phase and divided the heaviest component in the oil into nonprecipitating and precipitating components.In the study, a set of dummy experimental data tuned an equation-of-state based model that represents the asphaltene as pure component solid. Results of the work show that the select...
