“…Therefore, if the formations have sand problems, they need sand handling to prevent more severe production and reservoir problems. Tibbles, et al (2020) introduces several case studies of failures that occurred during sand control installations and details the investigative process and techniques used to identify the root causes. Examples include events such as screen/wash-pipe damage, bridging, hole collapse, and packer seal failure.…”

These paper contains a highlight of laboratory experiment to evaluate the work of chemical for sand consolidation to strengthen the bonding between grains of rock while do not cause permeability reduction significantly. This experiment used reservoir rock and fluids to understand the interaction between the chemical solution and the reservoir rock and fluid. Firstly, the reservoir rock and fluid were analyzed their properties. The rock has been analyzed using CT Scan to drill the best representative core plug for the experiments, using SEM to identify the pore throat and pore geometry of the rock, using XRD to determine the minerals composition which mostly quartz. While the fluids have been analyzed for the anions and cations content, viscosity and other important properties. The brine particle content and also particle size distribution of the rock have been also over lied in the graph in order to know the possibility of bridging particle in the pore throat, but the graph looks good that no problem may arise from the bridging particle. Chemical for Sand Consolidation has been used in this experiment. Sand consolidation chemical normally contain plastic resin that has a property of bonding between solid materials. It sticks on the surface of solid materials and bonding together.The core flooding experiments have been run for 4 times, 2 times using synthetic cores and the other two using native cores. The experiments used synthetic cores reduce the permeability significantly. However, after cutting both ends of the core the permeability has indicated improvement. The other 2 experiments using native cores have reduced the permeability approximately 4 times down. The last two experiments have no cutting the ends of core for further experiments, so they cannot be compared to the first two experiment. So, the experiment procedures must be improved for the next evaluation, such as during curing time the rate of injected oil may be increased to reduce the adsorption of chemical to the surface area of the pore and also to hinder the flocculation of chemical in the pore space.

Sand, or fines as some may call it, entering currently producing wells is one of the earliest problems faced by the Oil and Gas Industry in hydrocarbon recovery [Rogers, 1954; Carlson et al. 1992; McLeod 1994; JPT Staff 1995; Barrilleaux et al. 1996], and one of the toughest to solve in general [McLeod 1997]. Every year the petroleum industry spends significant capitol in cleaning and disposal costs, repair problems related to sand production, and lost revenues due to lower production rates due to mitigation efforts [Mathis 2003; Palmer et al. 2003]. Thus, sand control is, and should be, an integral part of well planning [Guerrero 2014] in unconsolidated reservoirs [Willson et al 2002; Chang 2006; Jaimes 2012], i.e., reservoirs where the rock has little or no natural inter-grain cementation. Sand production [Veeken et al. 1991; Subbiah et al. 2021] is caused by structural failure of the borehole wall rock due to drilling, degree of consolidation (very low compressive strength), the interaction between the rock and flowing fluids (production creates pressure differential and frictional drag forces that can combine to exceed the formation compressive strength), excessive drawdown causing fines and sand grain movement to the wellbore, or reduction of reservoir pressure. Sand production leads to adverse effects on various components in the wellbore and near wellbore area [Zamberi et al. 2014], such as tubing, casing, flowlines, and pumps, as well as surface equipment [Peden et al. 1984; Lidwin et al. 2013]. In addition, sand production may allow for the creation of downhole cavities [Peden et al. 1985] resulting in loss of structural integrity of the reservoir around the wellbore and ultimately possible collapse of the wellbore. Along with these possible issues, there is an additional economic impact in that sand must be separated out and disposed of at the surface and can be a few liters to several hundred cubic meters [Lidwin et al. 2013]. Decisions around sand production are not purely economic these days because regulatory and environmental restrictions have come to play a significant role in the decisions of how sand production will be handled. In general, what constitutes an acceptable level of sand production depends on operational constraints such as the ability to use erosion resistant materials, fluid separator capacity, sand disposal capability, and artificial lift equipment's capability to remove slurry from the well, but with that said, sand control methods that allow unconsolidated reservoirs to be exploited often reduce production efficiency. Thus, an effective design is always a balance between keeping formation sand in place without unduly restricting current and future productivity [Saucier 1974; Mathis 2003; Palmer et al. 2003; Lastre et al. 2013]. There are two primary methods of sand control these days, namely passive and active, where passive sand control uses perforation orientation and placement to try and mitigate sand production, while active sand control uses a more intrusive approach utilizing downhole filters [Tibbles et al. 2020]. Currently, the most popular and successful method of negating sand production is gravel packing around a downhole filter. In this method, gravel is deposited downhole by pure beta wave deposition in slightly deviated wellbores, i.e., wellbores having a deviation angle in the screen section less than about 50 degrees, or by what is normally referred to as alpha/beta wave deposition in highly deviated wellbores, i.e., wellbores where the screen section maximum deviation is greater than 50 degrees.
