Superparamagnetic iron oxide nanoparticles (IONPs), which have been investigated extensively as contrast-enhancing agents in biology, are being explored for subsurface applications such as electromagnetic tomography, fracture mapping, and enhanced oil recovery. However, two key challenges must be addressed: (a) high magnetic susceptibility and (b) colloidal stability and mobility under harsh reservoir conditions of high salinity and temperature. Herein, we synthesize IONPs grafted with poly(2-acrylamido-3-propanesulfonate-co-acrylic acid) poly(AMPS-co-AA) to achieve a high surface grafting density of polymer (49%) with minimal aggregation to yield sub-50 nm IONPs. The IONPs were found to be colloidally stable at 120 °C for a period of one month at pH 8. In crushed Berea sandstone, polymer-grafted IONPs exhibited significantly high mass breakthrough (84%) and low retention (149 μg/g) when used with a sacrificial polymer preflood (0.1% v/v). Intact Berea core experiments showed an 8-fold improvement in mass breakthrough (65%) and a two-thirds reduction in retention (from 433 μg/g to 160 μg/g) when compared to previous studies with IONPs synthesized via coprecipitation. The high grafting density of polymeric stabilizer and small nanoparticle size contribute to the improved mobility in consolidated porous media at high salinity.

“…Hamdi et al prepared functionalized GNPs by two different methods of mixing and grafting with natural gum arabic. 46 Polymer grafted GNPs (PG-GNPs) showed higher resistance to high temperature and salt compared to polymer dispersed GNPs (PD-GNPs) at low concentrations. The overall results of PG-GNPs showed better performance due to their higher stability compared to PD-GNPs.…”

“…Due to the higher fluid density, the efficiency of the well simulation process increases prominently. , The high-density brines modify the viscosity of the oil, which affects its mobility in the reservoir. This feature of HDBs improved the enhanced oil recovery (EOR). − The formation evaluation is done by employing HDBs in the wireline logging and well testing which could be utilized to create a contrast between the formation and the drilling fluid, which helps to easily interpret the data …”

Fluids for drilling and completion operations are essential components in the oil and gas industry. With the advancement of drilling technology, effective drilling fluid for harsh drilling operations is still challenging to exploit hydrocarbons. One of the prominent developments in this area is the application of high-density brines. The high-density brines have shown the capacity to tackle complicated harsh geological conditions. This review paper gives a detailed review of the properties, formulation, application, and importance of high-density brines in drilling and completion processes. The factors affecting the salient features of high-density brines, such as chemical composition, temperature, pH, and pressure, are discussed. Furthermore, the paper investigates the application of high-density brines in the oil and gas industry as drilling fluids, where they play a crucial role in wellbore stability, formation fluid control, and cuttings transport. In addition, this review highlights emerging trends and research to improve the performance of high-density brines. Finally, the review discusses current challenges and outlook, environmental concerns, economic feasibility, and compatibility with wellbore materials. The current ample review serves as beneficial literature for research scientists, engineers, and industry experts looking for a massive knowledge of high-density brines and their diverse applications.
