“…Portwood (1995) reviewed hundreds of projects and concluded that the cost of the MEOR process, including biosurfactants, ranges from USD 0.25 to 0.50 per barrel of oil produced and does not go up as oil production increases. A more recent study reported that the price of biosurfactants ranges between USD 2 and 3 per kg (Hazra et al 2011). It was reported that the reduction in IFT by the surfactants has to be ultralow (whereas the IFT values should be in the range of 10 −3 mN/m) to enhance oil recovery through increasing the capillary number (Aoudia et al 2006;Curbelo et al 2007;Zhu et al 2009;Iglauer et al 2010).…”

In this study, a biosurfactant produced by a Bacillus subtilis strain isolated from oil-contaminated soil from an Omani oil field was tested for its potential in enhancing oil recovery by a series of coreflooding experiments. It was found that the performance of the biosurfactant was increased by mixing with chemical surfactants, by which the maximum production went up to 50% of residual oil at a mixing ratio of (50:50). The second objective of this study was to investigate the effects of the biosurfactant on wettability alteration and to estimate its tendency to loss caused by adsorption. The influence of biosurfactant on wettability was studied by contact-angle measurements, atomic force microscopy (AFM) technique on few-layer graphene (FLG) surfaces, and Amott wettability tests on Berea sandstone cores. Contact-angle measurements showed that the wettability of the biosurfactant solution changes to more oil-wet as the angle decreased from 70.6 to 25.32° when treated with 0.25% (w/v) biosurfactant solution. Amott testing showed a change in wettability index from strongly water-wet in the untreated core toward less water-wet in biosurfactant-treated cores. These results confirmed the ability of the biosurfactant to alter the wetting conditions against different surfaces, thereby serving as a mechanism for enhancing oil recovery. The maximum loss of biosurfactant caused by adsorption was 1.2 mg/g of rock, which is comparable with reported chemical-surfactant values.

Injection of biosurfactant and chemical surfactant following hot water injection to enhance heavy oil recovery

et al. 2015

View full text Add to dashboard Cite

This study investigates the potential of enhancing oil recovery from a Middle East heavy oil field via hot water injection followed by injection of a chemical surfactant and/or a biosurfactant produced by a Bacillus subtilis strain which was isolated from oil-contaminated soil. The results reveal that the biosurfactant and the chemical surfactant reduced the residual oil saturation after a hot water flood. Moreover, it was found that the performance of the biosurfactant increased by mixing it with the chemical surfactant. It is expected that the structure of the biosurfactant used in this study was changed when mixed with the chemical surfactant as a probable synergetic effect of biosurfactant-chemical surfactants was observed on enhancing oil recovery, when used as a mixture, rather than alone. This work proved that it is more feasible to inject the biosurfactant as a blend with the chemical surfactant, at the tertiary recovery stage. This might be attributed to the fact that in the secondary mode, improvement of the macroscopic sweep efficiency is important, whereas in the tertiary recovery mode, the microscopic sweep efficiency matters mainly and it is improved by the biosurfactantchemical surfactant mixture. Also as evidenced by this study, the biosurfactant worked better than the chemical surfactant in reducing the residual heavy oil saturation after a hot water flood.

“…aeruginosa is one of the most popular strains employed for fermentation to produce glycolipid (Lee et al, 2008;Pornsunthorntawee et al, 2008;Huang et al, 2009;Qiang et al, 2009;Yin et al, 2009;Arutchelvi and Doble, 2010;Hazra et al, 2011;Muller et al, 2011;Saikia et al 2011). The reason might be that P. aeruginosa was easier comparatively to isolate and screen, easier to culture (results from this study showed that the growth period to reach exponential phase by batch seed culture was only about 8 to 10 h), and the higher yield of biosurfactant.…”

This study was to screen efficient biosurfactant producing strains from waste edible oils (WEOs). Two strains Y5 and Y17 were screened out by steps of preliminary blood plate screening and secondary flask fermentation screening. The surface tension of the fermentation broth of the two strains diluted by 100 times was lower than 40 mN/m. Preliminary characterization of fermentation products was conducted, which was found to be rhamnolipid ultimately. Y5 strain produced only one kind of glycolipids while the Y17 produced at least three kinds of homologues of glycolipids. Both Y5 and Y17 were identified as Pseudomonas aeruginosa strains. This study gave a simple and efficient protocol to screen out biosurfactant producing strains and would pave the way for the production of biosurfactant from WEOs.
