Dynamic stabilization of formation fines to enhance oil recovery of a medium permeability sandstone core at reservoir conditions

摘要: Fines migration has impacted the efficiency of low salinity water flooding at reservoir condition. However, previous studies on the use of nanoparticles to combat this problem were not done at reservoir condition and the effect of porous media length was neglected. Hence, the objective of this study is to use mesoporous silica (SiO2) nanoparticles (MSNP) to stabilize formation fines to increase oil recovery during low salinity water flooding at reservoir condition. Likewise, effect of porous media length on dynamic retention of fines at high temperature high pressure (HTHP) reservoir condition was investigated. The breakthrough curves of reservoir fines adsorption by mesoporous SiO2 nanofluid (MSNF) were described using the Thomas and Yoon-Nelson models. Subsequently, the effect of reservoir fines stabilization on oil recovery was evaluated using a HTHP core flooding equipment. Also, the formation damage …
