In this work, the precipitation of asphaltene from a Malaysian light oil reservoir was studies. A series of experiments were designed and carried out to examine the effect of CO2 injection on asphaltene precipitation. Different pressures of injections were used in Dynamic flooding experiment in order to investigate the effect of pressure versus injection pore volume of CO2. These dynamic displacement tests simulate reservoir condition. Results show that by increasing the pore volume of injected gas asphaltene precipitation will increases, also rise in injection pressure causes less precipitation. Sandstone core plug was used to represent reservoir formation during displacement test; therefore it made it possible to study the effect of present of asphaltene on formation. It is found out that the precipitated asphaltene can reduce permeability and porosity which is not favorable during oil production.<\/p>\r\n","references":"[1] Inge Harald Auflem, \"Influence of Asphaltene Aggregation and Pressure\r\non Crude Oil Emulsion Stability\", Doctor of Philosophy dissertation,\r\nDepartment of Chemical Engineering Norwegian University of Science\r\nand Technology ,Trondheim, June 2002 , pp. 10.\r\n[2] Sylvain Verdier, \"Experimental Study and Modelling of Asphaltene\r\nPrecipitation Caused by Gas Injection\", Doctor of philosophy\r\ndissertation, Department Of Chemical Engineering Technical University\r\nOf Denmark, 2007.\r\n[3] Faruk Civan , \"Reservoir Formation Damage Fundamentals, Modeling,\r\nAssessment, and Mitigation \", first edition , Gulf Publishing Company,\r\nHustun ,Texas , 2000,chapter 14, pp. 382.\r\n[4] Sunil L.
