The Effect of Fly Ash Nanoparticles on Foam Stability for CO2 Flooding †

Abstract

Foam–CO2 EOR Flooding is not very successful if unaccompanied by foam stabilizers such as nanoparticle fly ash (NFA). This study was conducted to determine the effect of NFA on foam stability by considering particle characteristics using the Bulk Foam Method as an additional condition. The test resulted in half-life times, which showed that in the absence of NFA, when oil was added, it was 211.5 s, and in salinity conditions, it was 232.5 s. This succeeds in improving half-life times to 226 s (with oil) and 241.5 s (with salinity) by adding NFA-Type F. For further research, conducting tests using reservoir conditions is recommended.
