An Investigation on the Effects of Charged Polyacrylamide Injection on Asphaltene Deposition in Porous Media

This study has been investigated, the effects of three different polar polyacrylamides (anionic, cationic, and nonionic) on asphaltene deposition in porous media. All experiments were carried out in various dead oil flow rates (0.2, 0.1 and 0.02 cc/min) and different polymer concentrations (500, 2500, 4000 ppm). The results indicated that asphaltene precipitation was affected by the presence of...

Simulation and Experimental Investigation of the Permeability Reduction due to Asphaltene Deposition in Porous Media

Experimental Investigation on Asphaltene Deposition in Porous Media During Miscible Gas Injection

In this work the likelihood of asphaltene deposition problems during dynamic displacement of oil by natural gas in unconsolidated porous media is experimentally inspected. The two different rock materials, limestone and sandstone, are used as a representative of porous media. Dynamic flow experiments indicate that the increase of natural gas injection inc...
