There are a lot of fine particles in sandstone reservoirs that are not strongly bonded to the rock's surface. These fine particles move with the fluid flow and cause formation damage and facilities' erosion. An effective method for preventing fine migration is using nanoparticles (NPs). In this study, modelling and experimental methods were utilized to investigate NPs' effect on fine migration. The Derjaguin–Landau–Verwey–Overbeek (DLVO) theory was used to model NPs' effect on the stability of fines on the rock's surface. Long sand packs were utilized to study the silicon dioxide NPs' effect on fine migration and location distribution of blockage in experiments at different pH and temperatures. Modelling results showed that the presence of NPs reduces the zeta potential of fine surfaces from −27.6 and −35.6 mV to −1.8 and −6.7 mV at pH = 8 and pH = 12, respectively. Based on the DLVO theory, it was concluded that NPs increase the particles' stability on the rock's surface. The experimental results showed that although fine migration increases with an increase in pH and temperature, the presence of SiO2 decreases it by 58% and 38% at pH = 8 and 12, respectively. The results showed that the performance of NPs reduced with an increase in pH and temperature. It was shown that the presence of NPs influences the location distribution of pressure drop and leads to permeability being more homogeneous in porous media during low salinity water injection.

The installation of sand screens in open-hole completions in the wellbore is crucial for managing sand production. The main reason for using standalone screens in open-hole completions is their relatively reduced operational complexity compared to other sand control technologies. However, directly applying the screen to the bottom of the hole can lead to an incorrect screen type selection, resulting in an unreliable sand control method. To address this issue, a sand retention test is conducted to evaluate the performance of a standalone screen before field installation. Nevertheless, current sand retention test setups encounter several challenges. These include difficulties in identifying minimum retention requirements, interpreting results in the context of field conditions, and replicating field-specific parameters. The existing sand retention test introduces uncertainties, such as inaccurately replicating field requirements, inconsistent selection of wetting fluids, flow rates, and channel formation, leading to variations in the choice of the optimal screen using this test. In response to these challenges, this study aims to review the sand retention test and propose an improved sand retention method to overcome these problems. The focus of this article is to provide an in-depth analysis of previous sand retention test setups, their contributions to characterizing sand screens, and the parameters utilized in determining test outcomes. Additionally, this review outlines a procedure to investigate the impact of different particle sizes on screen erosion. Key findings emphasize the importance of using high-quality materials, proper screen design to resist damage and erosion, achieving acceptable natural packing behind the screen, and considering factors such as geology, wellbore conditions, and installation techniques. The analysis reveals that a high quantity of finer and poorly sorted sand increases sand production. The study recommends performing a sand pack test closer to reservoir conditions for better evaluation. Premium sand screens demonstrate the highest retention capacity, followed by metal mesh and wire-wrapped screens. Additionally, geotextiles show potential for enhancing sand retention, and screen design affects erosion resistance and service life.
