Microbial Enhanced Oil Recovery (MEOR) is a potential technology for residual heavy oil recovery. Many heavy oil fields in Oman and elsewhere have difficulty in crude oil recovery because it is expensive due to its high viscosity. Indigenous microbes are capable of improving the fluidity of heavy oil, by changing its high viscosity and producing lighter oil fractions. Many spore-forming bacteri...
in the present study, the potential of a bacterial consortium of enterobacter cloacae and pseudomonas sp. (ercppi-2) for microbial enhanced oil recovery was investigated. various mechanisms of enhanced oil recovery (eor) as a result of using ercppi-2 and its metabolic products were studied in detail. the obtained results showed that under simulated reservoir conditions, interfacial tension redu...
Unconventional oils mainly heavy oils, extra heavy oils and bitumens represent a significant share of the total oil world reserves. Oil companies have expressed interest in unconventional oil as alternative resources for the energy supply. These resources are composed usually of viscous oils and, for this reason, their use requires additional efforts to guarantee the viability of the oil recove...
In this study, nanoparticle stabilized foam experiments were performed in bulk tests, micromodels, and sandpacks at elevated temperatures and pressures to investigate the flow behavior and displacement mechanisms for enhanced heavy oil recovery. The results from the bulk tests showed that the stability of the foam and oil in water (O/W) emulsion improved when silica nanoparticles (SiO2) were ad...
Introduction EOR This word literally means enhanced oil recovery and in the oil industry area used as extraction of oil reservoir that deals by advanced industrial techniques to harvest of reservoir heavy and semi-heavy oil [1]. In Canada 1.2 million barrels a day, Venezuela's 600,000 barrels per day and in China 150,000 barrels per day produced oil of heavy oil reservoirs. Canada, America, Ven...
since the pressure of hydrocarbon reservoirs drops due to production, in order to keep the production rate constant or increase enhanced recovery, few methods are used. one of which is gas injection to the reservoir. on the other hand, due to reduction in oil production potential of aghajari oil field, gas injection is highly required to pressurize and enhance oil recovery. there is a possibili...
This study examines the effects of change in the concentrations of monovalent and divalent ions in the polymer-contained surfactant solution on the macroscopic behavior of viscous-modified surfactant waterflooding in heavy oil reservoirs. Salts that are used in this set of floods were sodium chloride, magnesium chloride, and calcium chloride. The results indicate that four different ranges ...
