Abstract:
Asphaltene deposition is one of the main challenges during CO 2 injection (miscible or immiscible) into reservoirs. Asphaltene deposition reduces the porosity and permeability of reservoir rock and changes its wettability to strongly oil‐wet. In this article, to control the asphaltene deposition during CO 2 injection the use of direct asphaltene inhibitors (Al 2 O 3 and Fe 3 O 4 ) in reservoir conditions. In this research, nanoparticle screening (to investigate its significance in reducing asphaltene precipitation) has been done and it can be stated that Al 2 O 3 nanoparticle will perform better effectivity than Fe 3 O 4 nanoparticle. After that, by using effective nanoparticles (Al 2 O 3 ) in different concentrations (1000 and 2000 ppm), the amount of asphaltene deposition during CO 2 injection has been investigated. The obtained results show that increasing the injection pressure (from immiscible to miscible) causes an increase in asphaltene deposition and the use of nanoparticles will reduce the amount of asphaltene deposition.
