Effect of nanosilica injection to oil recovery factor in low porosity and permeability reservoir / Mursyidah Umar ...[et al.]

Porosity and permeability can be affected to oil recovery. Low porosity and permeability problems may cause oil flow from reservoir to wellbore becomes more difficult. A reservoir model has been prepared with 10.82% porosity and 28.8 mD Permeability using 30 mesh of homogenous sandstone. Nanosilica solution in water injection has been conducted in reservoir model. The result showed 5 % recovery factor incremental by injecting continuously 0.1% nano silica solution at 5 psi pressure. This means nanosilica injection has been successfully increase oil recovery.
