Physicochemical Characterization of Zirconia Nanoparticle-Based Sodium Alginate Polymer Suspension for Enhanced Oil Recovery

Abstract

Biopolymers have been employed in enhanced oil recovery (EOR) due to their high viscosity and significant effects on waterflooding performance. Sodium alginate (NaAlg) is an excellent biopolymer that is extracted primarily from brown algae. It has been used in the biotechnology industry as a thickening agent, colloidal stabilizer, and oil recovery application. In the present study, a series of sodium alginate/zirconium oxide nanoparticle suspensions were prepared via solution mixing, and the effect of nanoparticle content, polymer concentration, temperature, salinity was investigated on the rheological behavior using a concentric cylinder dynamic rheometer. The rheology results revealed that the lower concentration of sodium alginates (0.01 to 0.06 wt %) and sodium alginate/nanoparticle suspensions (0.02 to 0.06 wt %) displayed shear thinning behavior for the whole range of shear rate from 0.1 to 100 s–1. It was noticed that the aging of the polymer/nanoparticle suspension at 25 °C for 7 days did not significantly affect the rheological characteristics. It was moreover observed that enhancing salinity from 0.015 to 0.1 wt % in the 0.04 wt % ZrO2 nanoparticle suspension comprising 0.1 wt % sodium alginate showed a progressive decrease in viscosity under the temperature range from 25 to 50 °C. The proposed sodium alginate/zirconium oxide nanoparticles from the mentioned results indicate their potential for enhanced oil recovery applications.

Toward Improvement of Water-Based Drilling Mud via Zirconia Nanoparticle/API Bentonite Material

“…Nevertheless, these polymer-based drilling mud additives could be degraded at elevated reservoir conditions. 37,38 The metal oxide nanoparticles (NPs) can increase heat transfer properties and the viscosity of the drilling mud system. Therefore, the rheological characteristics of muds were modified using NPs because the high surface-to-volume ratio of NPs augments the colloidal behavior in the drilling mud system.…”

“…Recently, various synthetic polymers, such as polyanionic cellulose, guar gum, polyacrylates, starch, carboxymethyl cellulose, rice husk, xanthan gum, amphoteric cellulose, and polyacrylamide, have been employed as rheological modifiers and fluid-loss reducers in WBM.
