Formation Damage Induced by Water-Based Alumina Nanofluids during Enhanced Oil Recovery: Influence of Postflush Salinity

Abstract: Injecting nanofluids (NFs) has been proven to be a potential method to enhance oil recovery. Stranded oil is produced by wettability alteration where nanoparticles form a wedge film on pore wall surfaces, which is thought to shrink the pore space of the reservoir. Furthermore, ensuring the stability of the injected NF during the application is a major challenge. A low permeability reservoir and salinity of water make the response of NF injection to the formation damage more difficult. This article, therefore, … Show more

“…However, combing both the sonication and the magnetic stirring could prolong the stability of the nanofluid. Furthermore, Nguele et al [43] and later Ngo et al [47] reported that bubbling gas during the preparation could further enhance the stability regardless the type of base fluid (Figure 5).…”

“…With the presence of salt at the interface, the excess surface concentration turns positive from which results a low contact angle (Figure 7a) and higher IFT (Figure 7b). An oil production scenario in which the salt concentration is large, the salting-out effect seems to prevail [47].…”
