“…The presence of silica NP can substantially increase the surface charge, which can effectively suppress scale formation. Another study investigated the application of silica NP to control calcite sulfate scale at high temperature during water injection with high and low salinity (Moghadasi et al, 2019). It shows that the effectiveness of silica NP in controlling calcium sulfate scale is more pronounced at a higher salinity condition.…”

Oilfield flow assurance is the subject to study the impact on the flow of production fluids due to physicochemical changes in the production system. Mineral scale deposition is among the top 3 water-related flow assurance challenges in petroleum industry, particularly for offshore and shale operations. Scale deposition can lead to serious operational risks and significant financial loss. The most commonly adopted strategy in oilfield scale control is the deployment of chemical inhibitors. Although conventional chemical inhibitors are effective in inhibiting scale threat, they have the drawbacks of short transport distance and limited squeeze lifetime due to their intrinsic chemical properties. In the past decade, as an alternative to conventional chemical inhibition, research efforts have been made to prepare functional nanomaterials with different chemical compositions to overcome the drawbacks of conventional chemical inhibitors. These synthesized nanomaterials can serve as delivery vehicles to deploy inhibitors into the target location in the production system. These nanomaterials are reported to have multiple advantages over the conventional inhibitors in terms of transportability, controlled release, and functionality, evidenced by a series of experimental studies. This review presents an overview of scale inhibitor nanomaterial development and the current methods to synthesize and to evaluate these nanomaterials in a systematic and comprehensive manner. This review focuses on the chemistry principles and methodologies underlying inhibitor nanomaterial synthesis and also the chemical instrument and strategies in evaluating the physiochemical properties of these materials in terms of inhibition effectiveness, transportability, and inhibitor return. The scale inhibitor nanomaterials (SINMs) presented in this review exemplify the continuous development in our capabilities in adopting novel nanotechnology in combating actual engineering challenges in petroleum industry.

“…Carbonate reservoirs contain a substantial amount of the world’s oil reserves 1 , but unfortunately, their recoveries are not as high as enough 2 . Laboratory experiments and field trials have shown that enhanced oil recovery from carbonate reservoirs can be obtained by modifying the injected brine composition in a process called low-salinity water flooding (LSWF) 3 , 4 . LSWF is mostly adopted due to its relative simplicity, low cost 1 , easy implementation, and avoidance complexity of chemical additives such as polymers or surfactants 5 .…”

“…Due to the existence of some complicated processes in LSWFs, the mechanism by which low salinity water flooding improves oil recovery is not yet well understood, which results in uncertainties in the prediction of optimized low salinity water composition. There have been significant studies to understand the underlying mechanisms controlling LSWF, and several mechanisms have been proposed, including calcite dissolution 8 , the presence of sulfate (and/or dissolution of anhydrite) 4 , and changes in the carbonate mineral surface charge 9 . However, no mechanism has yet been shown to yield improved oil recovery 8 in all crude oil/brine/rock (COBR) systems; moreover, most fail to explain why published results (and much more unpublished) show no IOR with the dilution of injection brine 3 .…”

In low-salinity water flooding (LSWF), modifying the injected brine composition leads to greater oil recovery from carbonate reservoirs. The processes that control improved recovery during LSWF are not totally clear, which could lead to ambiguities in finding optimum brine composition regarding wettability alteration (WA) toward water wetness. One of the methods to determine WA is bound product sum (BPS) calculation using geochemical tools. In the case of wettability improvement, the BPS value of a crude oil-brine-rock (COBR) system should be at its minimum value. In this study, an improved geochemical model is developed, which includes the effects of oil composition (i.e., acid number, base number, and weight percent of nonhydrocarbon components) and physical properties of oil (i.e., density, viscosity, and solution gas-oil ratio) on COBR interactions. The proposed method generates BPS as a function of temperature, pressure, oil and brine composition, and pH for carbonate rocks. The model applicability was validated using several experimental data sets available in the literature. The results of the improved BPS model were in line with the results of contact angle and zeta potential measurements as the major indices of rock wettability. BPS calculations using the available geochemical tools sometimes failed to predict the correct WA trend since they overlooked the impact of oil properties on COBR interactions. The model predictability was also compared with the results of an available geochemical tool, PHREEQC, and the results demonstrate just how important the effect of oil properties and composition inclusion on wettability determination is. The improved BPS approach could be successfully utilized as an optimization tool to optimize the water composition during LSWF for a given COBR system.

Hydraulic fracturing has emerged as one of the best and most economical methods for enhancing oil recovery from low permeability reservoirs. However, its performance will be negatively affected by fines migration due to the hydraulic fracturing process. In the present study, it has been tried to experimentally investigate the efficiency of synthesized nanosilica particles in reducing fines migration. To this end, two sets of static and dynamic experiments, namely glass bead funnel test and core displacement analysis, were implemented, respectively. In the static test, increasing the soaking time and addition of nanosilica led to the clearer effluent fluid, resulting in fewer concentrations of clay particles in solution. When the mixture of nanosilica and glass beads was available in the solution, a higher differential pressure was obtained during a dynamic condition in comparison to only glass beads, which means the lower permeability of the porous media. Moreover, Derjaguin-Landau-Verwey-Overbeek theory was applied to demonstrate the clay particles absorption on the sand proppants surfaces. Consequently, it was observed that the use of nanosilica particles mixed with sand proppant can effectively reduce fines migration; thereby, it can enhance the hydraulic performance of the fracturing operation.
