“…Lan et al (2007) have investigated the synergistic effect of silica nanoparticles and CTAB on the stabilization of O/W emulsions and concluded that nanoparticles can improve the emulsion stability with the appropriate concentration of CTAB. Wu et al (2017) have indicated that silica nanoparticles can reduce the static and dynamic SDS surfactant absorption and thus enhance oil recovery. (Nwidee et al 2017) have concluded that the nanoparticle/ surfactant system can improve the wettability of the system and favors enhancing oil recovery.…”

Recently, nanoparticles have been used along with surfactants for enhancing oil recovery. Although the recent studies show that oil recovery is enhanced using nanoparticle/surfactant solutions, some effective parameters and mechanisms involved in the oil recovery have not yet been investigated. Therefore, the temperature effect on the stability of nanoparticle/surfactant solutions and ultimate oil recovery has been studied in this work, and the optimal concentrations of both SiO 2 nanoparticle and surfactant (sodium dodecyl sulfate) have been determined by the Central Composite Design method. In addition, the simultaneous effects of parameters and their interactions have been investigated. Study of the stability of the injected solutions indicates that the nanoparticle concentration is the most important factor affecting the solution stability. The surfactant makes the solution more stable if used in appropriate concentrations below the CMC. According to the micromodel flooding results, the most effective factor for enhancing oil recovery is temperature compared to the nanoparticle and surfactant concentrations. Therefore, in floodings with higher porous medium temperature, the oil viscosity reduction is considerable, and more oil is recovered. In addition, the surfactant concentration plays a more effective role in reservoirs with higher temperatures. In other words, at a surfactant concentration of 250 ppm, the ultimate oil recovery is improved about 20% with a temperature increase of 20 °C. However, when the surfactant concentration is equal to 750 ppm, the temperature increase enhances the ultimate oil recovery by only about 7%. Finally, the nanoparticle and surfactant optimum concentrations determined by Design-Expert software were equal to 46 and 159 ppm, respectively. It is worthy to note that obtained results are validated by the confirmation test.

“…Stable foams ensure fluid diversion from thief zones to lower permeability regions in the reservoir, while emulsions ensure conformance efficiency of the injectant [27,28]. Furthermore, surfactant nanofluids have been reported to have lower adsorption onto rock surface compared to ordinary surfactant solutions [29,30].…”

“…The addition of 0.3 wt.% SiO 2 nanoparticle concentration reduced the adsorption and dynamic retention of the surfactant by 43.6% to 0.66 and 0.06 mg/g, respectively. Furthermore, oil recovery displacement experiments in sand packs using a nanosurfactant solution showed a 4.68% incremental oil recovery factor over the oil recovery attained by the injection of conventional surfactant solution [29]. Suresh et al extended the adsorption studies on nanosurfactant to higher salinity and elevated temperature (80°C) conditions using thermogravimetric analysis (TGA) to determine the surfactant concentration in the produced fluids.…”

Chemical enhanced oil recovery (EOR) has been adjudged as an efficient oil recovery technique to recover bypassed oil and residual oil trapped in the reservoir. This EOR method relies on the injection of chemicals to boost oil recovery. Recently, due to the limitations of the application of chemical EOR methods to reservoirs having elevated temperatures and high salinity and hardness concentrations, nanotechnology have been applied to enhance its efficiency and improve oil productivity. The synergistic combination of nanoparticles and conventional EOR chemicals has opened new routes for the synthesis and application of novel materials with sterling and fascinating properties. In this chapter, an up-to-date synopsis of nanotechnology applications in chemical EOR is discussed. A detailed explanation of the mechanism and applications of these novel methods for oil recovery are appraised and analyzed. Finally, experimental and laboratory results were outlined. This overview presents extensive information about new frontiers in chemical EOR applications for sustainable energy production.

“…As for the kinetic, the mixture was shaken and sample collected at the designated time interval until concentration of lignosulfonate achieved constant. Depletion method (Wu et al, 2017) using UV-Vis to measure the lignosulfonates concentration before and after adsorption. The difference between the initial and after adsorption gave the amount of lignosulfonate adsorbed in mg/g.…”

Lignosulfonates adsorption onto clay as sacrificial agent â€“ benchmarking for Enhanced Oil Recovery

This study is to investigate the adsorption capability onto kaolinite for different types of lignosulfonates in various salinity environment. Depletion method using the UV-Vis were used for measuring the concentration of lignosulfonate before and after the adsorption process in equilibrium and kinetic conditions. The highest amount of lignosulfonate adsorbed potrayed the best sacrificial agent that can be used in enhanced oil recovery application. The highest amount adsorbed of lignosulfonate onto kaolinite can prevent the surfactant lost into the formation. Among the four tested lignosulfonates, sodium lignosulfonate appeared the best in terms of adsorption capability in the presence of NaCl and CaCl2 salt in the system. Freundlich isotherm model was the best to describe the equilibrium adsorption data of sodium lignosulfonate. On the other hand, pseudo-second order model was the best to describe the kinetic adsorption data of sodium lignosulfonate.
