A17 Visualization of the Effects of Pressure and Gas CO2 Content on Asphaltene Precipitation while Displacement of Oil Via Gas S. Nejadi (Arvandan Oil and Gas Production) V.A. Sajjadian* (Arvandan Oil and Gas Production) & M. Jahedi (Arvandan Oil and Gas Production) SUMMARY Asphaltene precipitation is a fact that leads to significant problems due to incompatibility of the fluids while gas injection to an oil reservoir for pressure maintenance or EOR purposes. In the current research nine experiments were carried out to study problems which might encounter while that mentioned phenomena. Sample of a gigantic Iranian gas reservoir combined with
