“…Further, they were effectively reducing the IFT between diesel and water. It is considered as an important factor in oil recovery because capillary number increases with the decrease in the interfacial tension (Hajibagheri et al 2017). The CMC values were found to be in the range of 105±0.34, 90±0.58, 65±0.94 mg.L −1 respectively.…”

“…This is due to the fact that biosurfactants start to decrease the interfacial tension at oil/brine interface which in turn increases the capillary number of the system. Further, increase in capillary number lowers the residual oil saturation in the column and increases the recovery process (Hajibagheri et al 2017). The recovery process from the saturated sand pack column was unaffected between 70 − 90˚C, which indicates the stability of biosurfactants.…”

Petroleum and hydrocarbons contamination can be remediated by physical, chemical or biological methods. Among these, in situ bioremediation is considered to be environmentally friendly because it restores the soil structure, requires less energy input and involves the notable removal after degradation of biosurfactant. The present study involves the characterization and assessment of biosurfactant producing indigenous hydrocarbonoclastic bacteria and their potential application in bioremediation processes. Three bacterial strains were isolated from various crude oil contaminated environments and characterized using standard identification techniques. The results clearly demonstrate the capability of utilizing hydrocarbon and biosurfactant produced by the bacterial strains. 16S rDNA sequencing followed by BLAST analysis revealed their similarity to Pseudomonas aeruginosa. The physico-chemical characterization of the biosurfactants revealed significant surface properties with stability at extreme temperature conditions (up to 121˚C), pH (5 - 8) and salinity (up to 4 %). Further, the mass spectrometry confirmed predominance of di-rhamnolipids in biosurfactant mixtures. The biosurfactants were found to be efficient in the removal of crude oil from the contaminated sand suggesting its applicability in bioremediation technology. Further, improved discharge of crude oil at elevated temperatures also confirms their thermo-stability which, could be exploited in microbial enhanced oil recovery processes. Thus, the applications of biosurfactants produced by the indigenous hydrocarbonoclastic strains appeared to be advantageous for bioremediation of petroleum-contaminated environments.

“…Recently Hajibagheri et al (2017Hajibagheri et al ( , 2018 and (Najafi-Marghmaleki et al 2018) studied the effect of different biosurfactant-producing bacteria on the wettability of oil-wet carbonate surfaces. Hajibagheri et al (2017Hajibagheri et al ( , 2018 showed that bacterial solution of Enterobacter cloacae can change wettability of calcite surfaces from a strongly oil-wet state toward a strongly water-wet state. Najafi-Marghmaleki et al (2018) showed that bacterial solution of an Alcaligenes faecalis strain can change the wettability of an oil-wet carbonate surface toward a neutral-wet condition.…”

“…Najafi-Marghmaleki et al (2018) showed that bacterial solution of an Alcaligenes faecalis strain can change the wettability of an oil-wet carbonate surface toward a neutral-wet condition. Note that the bacterial solution experimented by Hajibagheri et al (2017Hajibagheri et al ( , 2018 and Najafi-Marghmaleki et al (2018) is composed of both bacteria cells and bioproducts. Therefore, following questions are left unanswered:…”

“…For MEOR, the positive answer to the first question can make MEOR process applicable where it is not regarded to be applicable. By looking into the work of Hajibagheri et al (2017Hajibagheri et al ( , 2018 and Najafi-Marghmaleki et al (2018), one can see the bacterial solution has a significant concentration of K 2 HPO 4 and KH 2 PO 4 , as phosphate ions are essential for biosurfactant production. In the real field application, injection of such solution into the reservoir is not possible, as it is not compatible with the carbonate reservoirs brine [with a significant concentration of Ca 2+ (Austad 2013)].…”

In upstream oil industry, microorganisms arise some opportunities and challenges. They can increase oil recovery through microbial enhanced oil recovery (MEOR) mechanisms, or they can increase production costs and risks through reservoir souring process due to H 2 S gas production. MEOR is mostly known by bioproducts such as biosurfactant or processes such as bioclogging or biodegradation. On the other hand, when it comes to treatment of reservoir souring, the only objective is to inhibit reservoir souring. These perceptions are mainly because decision makers are not aware of the effect microorganisms' cell can individually have on the wettability. In this work, we study the individual effect of different microorganisms' cells on the wettability of oil-wet calcite and dolomite surfaces. Moreover, we study the effect of two different biosurfactants (surfactin and rhamnolipid) in two different salinities. We show that hydrophobe microorganisms can change the wettability of calcite and dolomite oil-wet surfaces toward water-wet and neutral-wet states, respectively. In the case of biosurfactant, we illustrate that the ability of a biosurfactant to change the wettability depends on salinity and its hydrophilic-hydrophobic balance (HLB). In distilled water, surfactin (high HLB) can change the wettability to a strongly water-wet state, while rhamnolipid only changes the wettability to a neutral-wet state (low HLB). In the seawater, surfactin is not able to change the wettability, while rhamnolipid changes the wettability to a strongly water-wet state. These results help reservoir managers who deal with fractured carbonate reservoirs to design a more effective MEOR plan and/or reservoir souring treatment strategy.
