| Popis: | In a CO2 gas displacement process, the injected CO2 can disturb the reservoir fluid stability and induce flocculation and deposition of asphaltenes. Several procedures are used to remove or prevent asphaltene precipitation, but the uses of asphaltene inhibitors provide most practical and economical solution for deposits treatment. In this work, the results obtained on the inhibition effect of one commercial inhibitor namely IR95 and five non-commercial inhibitors namely benzoic acid, nonylphenol, phenanthrene, phthalic acid, and salicylic acid is presented. Static tests indicate that CO2 concentration and temperature are the most important factors on which the asphaltene precipitation depended. Results of inhibitor tests reveal that IR95 with more than 50% precipitation reduction have best efficiency among other inhibitors. |
