“…The systems presented low viscosity values, however, polymer systems showed higher viscosity than water and brine used in EOR processes (KCl 2%). In this case, these systems are expected to have greater mechanical displacement power, avoiding preferred paths, "fingers," and, consequently, the increase in the oil displacement efficiency (Teixeira, 2012;Viana et al, 2015;Castro Dantas et al, 2017;Dantas et al, 2019).…”

“…The co-surfactant consists of a short-chain alcohol, such as butan-1-ol, used to act directly on the packaging factor and its function is to reduce the repulsion of the polar "heads" of the surfactants, stabilizing the micelle (Castro Dantas et al, 2017;Garnica et al, 2020;Curbelo et al, 2021). Microemulsions differ from conventional emulsions because they allow the stabilization of immiscible, thermodynamically stable, translucent, isotropic mixtures and have much smaller structural units (Gurgel, 2004;Gradzielski, 2008;Soares, 2011;Viana et al, 2015;Castro Dantas et al, 2019). According to Rossi et al, (2006), Castro Dantas et al (2017 and Curbelo et al (2021), in the microemulsion, with ionic aggregates, the phases are organized similarly to the emulsion.…”

“…Source: Rossi et al (2006) Due to these characteristics, microemulsion systems have a great potential for application in the oil industry. They are used, in the solubilization of oil sludge (Viana, 2013;Silva et al, 2019), and the treatment of produced water (Castro Dantas et al, 2018;Silva et al, 2020). They also work as, fracturing fluids (Ribeiro et al, 2016) and in advanced oil recovery (Hendraningrat et al, 2013;Castro Dantas, 2014;Shafiee et al, 2017;Sharma et al, 2017;Oliveira et al 2017, Castro Dantas et al, 2017Dantas et al, 2019).…”

Fluids in terms of rheological behavior can be classified into Newtonians and non-Newtonians. Newtonians are fluids that have unique and absolute viscosities, because the ratio between shear stress and shear rate is constant. In the oil industry, most fluids, such as microemulsions, oil and polymeric solutions, do not exhibit Newtonian behavior. To understand the behavior of chemical fluids, it is necessary to analyze some parameters to interpret their properties and applicability. In this context, the present work aims to obtain and characterize microemulsion systems containing Alkali, Surfactant, and Polymer, and verify their applicability in advanced oil recovery. Thus, we obtained five microemulsion systems consisting of saponified coconut oil (surfactant), Butan-1-ol (co-surfactant), kerosene (oil phase), Na2CO3 (alkali), water and different percentages of the polymer. The systems were characterized by analyzes of particle diameter, surface tension, viscosity and rheological behavior using mathematical models. Droplet sizes showed characteristic values of micellar aggregates. Surface tension presented a slight elevation when the percentage of polymer in the microemulsion increased. Through the rheological study, it was possible to observe that experimental values were better adjusted to the Ostwald-de Waele “power-law” model. As the percentage of polymer in the system increased, we calculated the apparent viscosity of the systems and observed an increasing change in viscosity values, a result of great interest to enhanced oil recovery studies.

“…There are different techniques for the treatment of oily sludge, and the choice depends on the desired aim to be achieved [ 8 ]. Various oily sludge treatment methods include centrifugation, froth flotation, solidification/stabilization, solvent extraction, surfactant EOR (enhanced oil recovery), landfarming, pyrolysis, biodegradation, photocatalysis, ultrasonic treatment, and incineration [ 9 , 10 , 11 , 12 , 13 ]. Researchers have concluded that it is ineffective to implement a typical method to fully remove the dangers of the oily sludge without any side-effects, and these methods may either partially or fully decrease the harmful substances in petroleum sludge to a minimum acceptable level [ 14 ].…”

In the industries of petroleum extraction, a large volume of oily sludge is being generated. This waste is usually considered difficult to dispose of, causing environmental and economic issues. This study presented the novel experimental method of manufacturing mortar used in civil construction by cement and oily sludge ash (OSA). The defined method was described with a logical experimental study conducted to examine a feasible manufacturing method for casting cement-based mortars by partially replacing cement with OSA. Replacement concentrations for OSA ranged from 0 to 20 percent by cement weight, while the water-to-cement (w/c) ratio was varied from 0.4 to 0.8, and the amount of sand was kept constant. The strengths and absorption rate of the mortar were monitored for 28 days. The OSA contains a crystalline structure with packs of angular grains. Because of OSA in the cement-based mortar mixtures and water-to-cement ratios, the mechanical strength was improved significantly. However, the water absorption trend increased linearly. Using variance analysis, the influence of OSA and w/c ratio on the behavior of mortar was acquired. The developed models were significant for all p-value reactions of <5%. Numerical optimization results showed that the best mixture can be obtained by replacing 8.19 percent cement with OSA and 0.52 as a ratio of w/c.

“…There are different techniques for the treatment of petroleum sludge, and the choice depends on the desired aim to achieve (Ramirez and Collins, 2018). The removal methods of oil from the petroleum sludge can be done by froth flotation, surfactant EOR (enhanced oil recovery), microwave irradiation, ultrasonic radiation, solvent extraction, freeze/thaw, centrifugation, pyrolysis and electro-kinetic (Hu et al, 2017;Nazem and Tavakoli, 2017;Shen et al, 2016;Silva et al, 2019;Pazoki and Hasanidarabadi, 2017). These methods may either partially or totally decrease the harmful substances in petroleum sludge to a minimum acceptable level (Gong et al, 2017).…”

Oil companies are largely responsible for producing a huge amount of petroleum sludge (PS), which is a major source of pollution in the environment. It is generated during oil extraction, processing, transportation, and cleaning activities. Environment Protection Act and Hazardous Wastes Handling Rules categorized petroleum sludge as hazardous waste because it consists of spent chemicals, wastewater, waste oil, mineral matter, and contaminated sand. This PS cannot be disposed of in a landfill, even after it is effectively de-oiled. However, PS treatment and disposal are serious threats for most refineries. Thus, the treatment became crucial. In this paper, a comprehensive review of PS sources, characteristics, environmental effects along with the comparative analyses of available thermal and disposal methods of PS treatment are presented. This review paper could enhance the essential knowledge and future guide for PS thermal and disposal techniques.
