“…These methods consist of screens, slotted liners, gravel packs, and screenless completion methods. Slotted liners are cylindrical screens installed on the wellhead blocking the passage of sand particles, similar to a filter, while not occluding the oil flow. − The second categorysurface methodsincludes some screens such as a strainer to separate the sand in the oil. Desanders are then used to apply a kinetic energy difference, such as centrifuge, and finally, membranes are used to remove very fine sand particles. − …”

This review aims to bring together the studies on petroleum reservoirs’ sand production control in a comprehensive guide for the researcher to compare various methods for the chemical consolidation of sand. Sand production can be considered one of the major challenges in the petroleum production industry, causing severe operational issues. This study introduces various methods to control and prevent sand production in petroleum wells and evaluates their advantages and performance in tabular form. The use of chemical procedures is considered to be more efficient in counteracting the production and migration of sand. Various chemicals and polymers have been proposed for this purpose. These chemicals should increase the consolidation of the formation rock while not reducing its permeability. The complexity and simplicity of the substances will be the two main factors. Novelties are generally tied with complex chemical structures. Conversely, simplicity makes them affordable, which is essential for industrialization. Success is obtained when the two are combined. This Review is expected to allow individual experts to compare various methods and be a handbook guiding them in the pursuit of finding the appropriate method of sand control for each reservoir.

“…Ojo et al [22,23] established a three-dimensional mathematical model of gravel packing in horizontal wells under the influence of multiple factors and predicted the balanced height of sand bed during gravel packing process in horizontal wells. When Dong et al [24][25][26] conducted a numerical simulation study on the gravel packing process in horizontal wells, they took into account the influences of sand-carrying fluid filtration to the formation and fluid mass exchange between wellbore annulus and scrubber annulus on gravel packing. They not only set up the mass conservation equation and momentum conservation equation of the gravel and sand-carrying fluid for two independent flow systems of wellbore annulus and scour annulus, but also set up the flow coupling equation of each system.…”

The gravel packing completion method for horizontal wells has the advantages of maintaining high oil production for a long time, maintaining wellbore stability, and preventing sand production, so it has become the preferred completion method for horizontal wells. At present, this technology still faces the problems of high sand bed height and poor gravel migration. In order to improve the efficiency of gravel packing in horizontal wells, pulsed gravel packing technology for horizontal wells is proposed for the first time. Based on the mechanism of hydraulic pulse, the Eulerian–Eulerian model, k-ε model based on the renormalization group theory (RNG k-ε model), and Fluent are used to simulate the solid-liquid two-phase flow. By optimizing the parameters such as frequency and amplitude of pulse waveform, the optimal pulse waveform of pulsed gravel packing in horizontal wells is determined. The effects of parameters such as sand-carrying fluid displacement, sand-carrying fluid viscosity, sand-carrying ratio, gravel particle size, and string eccentricity on pulsed gravel packing in horizontal wells are studied, and the distribution law of gravel migration velocity and volume fraction in horizontal wells is obtained. According to the results, it can be seen that with the increase of displacement and viscosity of carrier fluid, the volume fraction of fixed bed and moving bed decreases gradually, while that of suspension bed increases gradually. With the increase of sand-carrying ratio, gravel particle size, and string eccentricity, the volume fraction of fixed bed and moving bed increases gradually, while that of suspended bed decreases gradually. Comparing the effects of conventional gravel packing and pulsed gravel packing in horizontal wells, it can be concluded that the efficiency of pulsed gravel packing in horizontal wells is higher. The volume fraction of fixed bed and moving bed decreased by 30% and 40% respectively, while the volume fraction of suspended bed increased by 20%. The migration velocity of moving bed and suspended bed increased by 40% and 25%, respectively, and the migration ability of gravel improved obviously.
