The application of nanoparticles for enhanced oil recovery (EOR) has been shown to be advantageous over conventional methods. Wettability alteration reservoir rock from oil-wet water-wet is one the main factors in improving matured reservoirs. sandstone reservoirs are generally negatively charged, and hence, a proper selection surface charge important. In this work, novel nanofluid prepared usi...

Abstract This study is a continuation of our previous work, which focused on near-wellbore water blockage alleviation by applying thermally cured silane-functionalized benzoxazine to modify rock wettability. In this new analysis, we have demonstrated that the resin can be applied in low-permeability sandstones (approximately 15 mD as opposed 100 200 study) change surface wettability from water-...

A network model that investigates electrical resistivity and capillary pressure curves of oil/water/rock systems for a full̄ooded cycle (primary drainage, imbibition and secondary drainage) is presented. This model uses a realistic pore geometry in the form of a grain boundary pore (GBP) shape and pore constrictions. The model also incorporates pore-scale displacement mechanisms and pore-scale w...

Chelating agents’ application for well stimulation is gaining more and interest, as they can perform under harsh conditions. However, the mutual influence of surfactants chelating agents on wettability alteration hydrophobic carbonate rock conditions high-temperature relatively unexplored. This paper aims to study interfacial processes surface in presence EDTA-based agent different classes. Cat...

We present a three-dimensional network model to simulate two- and three-phase capillary dominated processes at the pore level. The displacement mechanisms incorporated in the model are based on the physics of multiphase flow observed in micromodel experiments. All the important features of immiscible fluid flow at the pore scale, such as wetting layers, spreading layers of the intermediate-wet ...

This study introduces a zeta potential-based model which connects low salinity water flooding oil recovery to the reservoir wettability. The assumed that wettability is controlled by electrostatic forces exist between rock-brine and oil-brine interfaces. Therefore, it links potentials present at corresponding Using model, various literature data were simulated then statistically compared trend ...
