“…According to American Petroleum Institute (API), crude oils are classified by relative density classified in 4 groups light (API > 31.1), medium (API from 22.3 to 31.1), heavy (API < 22.3) and extra heavy (API < 10.0). Regarding crude oil production, the underground pressure in well is used as drive force for oil recovery -primary technique -that recoveries ≈ 5-10% of original oil in well [4]. The secondary technique of oil recovery is very often accomplish by water-flooding (injection of water at top of well), that recoveries ≈ 10-40% [1][2]4].…”

Therefore, every stripper well has about 50-85% of original oil in well [1][2]4]. Thus, the aim of enhanced oil recovery technologies is mainly the residual oil in the stripper wells -after the primary and secondary techniques of oil recovery -which is estimated at ≈2-4 trillion barrels [2].…”

“…Microbial enhanced oil recovery (MEOR) is one of the most important tertiary recovery processes. Preliminary studies were carried out in the 1950s (US, Eastern Europe, USSR and Netherlands), since then researches in oil production and exploration has indicated that MEOR should be apply in stripper wells (less than 10 oil barrel/day), in which some parameters must be taken into account such as type of formation (sandstone), depth, temperature, pressure, reservoir rock permeability, gravity of oil, viscosity of oil, water cut, pH, residual oil saturation and ionic strength [4]. MEOR technique lies on the application of microorganisms (in situ) or their metabolic (ex situ) into the oil wells.…”

“…Both, in situ and ex situ MEOR act on the reduction of surface and interfacial ten-sion, gas production (increasing the differential pressure driving), selective plugging, biodegradation, and wettability alteration, etc., in which biosurfactants (interfacial tension, emulsification and higher bacterial mobility), polymers (viscosity of flood water and selective plugging), solvents (carbonate rock) and biomass (selective plugging) are used to enhance the oil recovery [4]. The state of art on MEOR indicates the in situ strategy instead of ex situ due to the its lower operating costs, in particular applying indigenous biosurfactant-producing bacteria [4]. In situ MEOR is very often operates in a cyclic manner and experiments at field trial scales were already described, for instance, Le et al [5] detailed that 6.3 x 10 4 tons of oil were recovered (in situ strategy) from 518 wells.…”

Worldwide oil production has been declining. Microbial enhanced oil recovery is one of the most important tertiary recovery processes. The aim of this work was to evaluate the surface activity properties of surfactin and mannosylerithritol lipids-B. In our previous studies, surfactin and mannosylerithritol lipids were produced using cassava wastewater as substrate and then purified by ultrafiltration. Thus, this work extends our previous studies. Experiments of surface activity under extreme conditions (temperature, ionic strength and pH), oil displacement, removal of oil from sand and emulsification index were carried out. Central composite rotational design was performed under extreme conditions of temperature, pH and ionic strength. The results indicated that ionic strength significantly affected the surface activity of surfactin. On the other hand, ionic strength, but also temperature and pH significantly affected the tenso activity of mannosylerithritol lipids-B. Regarding oil displacement test, mannosylerithritol lipids-B showed higher clear zone than surfactin. Contrary, in the experiments of removal of crude oil from sand, minimal differences were observed between surfactin and mannosylerithritol lipids-B. Therefore, both surfactin and mannosylerithritol lipids-B showed good surface activity under extreme conditions. In addition, it seems that mannosylerithritol lipids-B is subtly better than surfactin for microbial enhanced oil recovery.

Biodegradation of heavy oil by fungal extracellular enzymes fromAspergillusspp. shows potential to enhance oil recovery

et al. 2021

Microbial enhanced oil recovery makes a substantial contribution to the recovery of heavy oils; however, most methods use bacteria, with less attention paid to the potential of fungi. In this study, we investigated the efficiency of fungal extracellular enzymes in biotransformation of heavy oil fractions into light compounds. Two Aspergillus isolates (A. terreus and A. nidulans) with the ability to biodegrade heavy oil were isolated from bitumen. The extracellular enzymes from these Aspergillus isolates exhibited dehydrogenase and catechol 2,3‐dioxygenase activities. The biodegradation of heavy oil was coupled with abundant production of gases, mainly CO2 and H2. Gas chromatography analysis revealed a redistribution of n‐alkanes in heavy oil after treatment with crude enzyme extracts, which resulted in an increase in individual n‐alkanes. The viscosity of heavy oil was decreased considerably by enzymatic degradation. These results demonstrate the potential of fungal extracellular enzymes from Aspergillus spp. for applications in enhanced heavy oil recovery.

The monomers containing phenylsulfonamide N-allyl-4-methylbenzenesulfonamide (TCAP) and N,N-diallyl-4-methyl benzenesulfonamide (TCDAP) were copolymerized with acrylamide (AM), acrylic acid (AA), and 3-(3-methacrylamidopropyl-dimethylammonio)-propane-1-sulfonate (MDPS), respectively, through free-radical micellar copolymerization in deionized water for enhanced oil recovery (EOR). Then, the effect of the synthesis conditions was investigated simultaneously; the copolymers were characterized by Fourier transform infraredFTIR, nuclear magnetic resonance, scanning electron microscopy, and thermogravimetric analysis. It was found that the thickening function, high-temperature resistance (120 C), and anti-shear ability were improved significantly. It was also found that the copolymers had excellent viscoelasticity at the lower shear frequencies. When the copolymers were dissolved in 10,000 mg L −1 NaCl, 2000 mg L −1 CaCl 2 , and 2000 mg L −1 MgCl 2 solutions, the viscosity retention rates of AM/AA/TCAP/MDPS and AM/AA/TCDAP/MDPS were 13.3, 11.1, 10.6% and 18.6, 15.2, 11.7%, respectively. In addition, the copolymers for EOR at 60 C were 11.4 and 13.8%, respectively, which demonstrated that the copolymers possessed excellent performance for potential application in EOR.
