چکیده
In Ecuador, heavy crude oil represents 20% of the proven reserves at national level. However, producing them has been challenging because their low recovery factor due to characteristics, high viscosities, and mobility, among others. This makes developing implementing improved or tertiary methods technologies necessary; therefore, aim is produce maximum available resources in an environmentally friendly way. New advances hydrocarbon extraction recent years have tested one them, on which this research focuses, using chemical solvents are injected modify viscosity aqueous solutions. Thus, displacing generates very interfacial tensions between water by adsorption liquid-liquid phase. Therefore, selection a reservoir that meets required characteristics for respective application method was carried out. Furthermore, increasing sweep efficiency will optimize mobility bank toward wells, thus improving factor. Consequently, upon running simulation, results show continuous surfactant flooding resulted 84.5% recovery, SP 89.4%, ASP with highest 90.13%. synergistic contribution IFT reduction ratio per polymer reduction, overall better margin. At same time, alkali responsible decreasing amount active used as it lower-cost agent [1].

Microbial Enhanced Oil Recovery Using Biosurfactant Produced by Alcaligenes faecalis
A bacterial strain (designated as Alcaligenes sp. MS-103) isolated from oil sample of the Aghajari oilfield in the south of Iran, was able to produce an effective extracellular lipopolysaccharide biosurfactant (1.2±0.05 g/l) on molasses as a sole carbon source. The highest surface tension reduction to level 20 mN/m was achieved by biosurfactant produced by cells grown on molasses under optimum ...
متن کاملNumerical Simulation of Chemical Enhanced Oil Recovery Processes
In this paper we develop a new mathematical formulation for chemical compositional reservoir simulation, and provide a comparison of its results on alkaline-surfactant-polymer flooding with those of UTCHEM simulator. Our research has found that the existing chemical compositional model estimates the adsorption effect on the transport of a component reasonably well but it does not satisfy the pr...
متن کاملEffect of polysilicon nanoparticles on enhanced oil recovery in Iranian oil reservoir
Recovery Factor is an important parameter in determining commercial viability of the oil Reservoirs. Wettability is a major factor that affects oil Recovery. Therefore, changing rock wettability may enhance oil recovery. In this paper, the effect of polysilicon nanoparticles on wettability change of Iranian carbonate reservoir is investigated. To assess this, hydrophilic changes of carbonate ro...
