Abstract

[Display omitted] • The two-step method is best suited for designing bionanomaterials for oil recovery. • Bionanomaterials crystal phase, size, morphology, hydrophobicity and charge controls EOR mechanisms. • Designed bionanofluid can increase oil recovery and are stable at reservoir condition. • Lack of knowledge sharing between academia and industry has limited field application. To minimize environmental impact and costs, bionanomaterials have been proffered. However, their performance hinges on material and intensification of synthesis methods. Herein, design of bionanomaterials towards oil recovery applications are presented. Methods of synthesizing bionanomaterials were discussed. Process intensification of synthesis methods was elucidated and basic driving force during synthesis were identified. Challenges prevalent during design and application of bionanomaterials have opened new opportunities for research and are incorporated with proposed solutions. In absence of Ostwald ripening, nucleation rate and growth processes can control size and shape of nanocrystal. Hence, designing bionanomaterials, nucleation rate should be determined alongside supersaturation. [ABSTRACT FROM AUTHOR] more...

Abstract

Iron oxide nanoparticles (IONPs) are of particular interest in multiple fields and in enhanced oil recovery (EOR) due to their unique advantages and characteristics. Albeit several laboratory research articles on IONPs in EOR are available, a critical review is still elusive in literature. Herein, critical information on the properties, formulation and application of IONPs in oil recovery is depicted. The basic physical, structural and physicochemical properties of IONPs were introduced. Thereafter, the preparation of iron oxide nanofluids (IONFs) was discussed. Likewise, potential application of IONPs, in petroleum industry was elucidated. Subsequently, effectiveness of IONPs in EOR was compared with other nanoparticles and the efficacy of surface coatings were reviewed. Finally, the main challenges hindering the applications of IONPs in oil field reservoir were identified and solutions proffered. Experimental results from the literature indicate that the effectiveness of IONPs in reservoir applications is directly related to their surface coatings. The coatings are used to enhance stability and transportation, minimise rock adsorption, and target specific oil recovery mechanisms, resulting in incremental oil recovery. Hence, surface treatment is a necessity for reservoir condition applications. [Display omitted] • The bottom-up approach offers superior control and flexibility. • Growth process determines the final size, particle distribution and shape of the IONPs. • Salinity has the most devastating effect on the transport, retention and oil recovery system of IONFs. • IONPs are very economical, ecologically benign and has potentials for oil field applications.
