“…[3][4][5] Surfactants act as dispersants, emulsiers, IFT reducers, wettability changers, demulsiers, and wetting and foaming agents. [6][7][8] However, many surfactants suffer in a harsh reservoir environment where high temperature and high salinity (HTHS) results in degradation. Moreover, adsorption on formation rocks makes many surfactants inapplicable.…”

“…The temperature of 30 °C was considered in order to ensure the wettability alterations measured in this work are solely due to the effect of added bioproducts (active/inactive biomass or biosurfactant) not the distilled water or the seawater (Austad et al 2011;Mahani et al 2015). Note that the time period of 1 week was chosen because Hajibagheri et al (2017Hajibagheri et al ( , 2018 observed that the wettability alterations mainly occurs in the first 3-6 h. Therefore, we assumed that the time period of 1 week is long enough for any potential changes to show up. Najafi-Marghmaleki et al 2018, in their contact angle measurements, placed rock slices in different solutions including a formation brine and microbial solutions.…”

“…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.

Microbial communities capable of hydrocarbon degradation linked to biosurfactant (BS) and bioemulsifier (BE) production are basically unexplored in the Gulf of México (GOM). In this work, the BS and BE production of culturable marine bacterial hydrocarbonoclasts consortia isolated from two sites (the Perdido Fold Belt and Coatzacoalcos area) was investigated. The prospection at different locations and depths led to the screening and isolation of a wide variety of bacterial consortia with BS and BE activities, after culture enrichment with crude oil and glycerol as the carbon sources. At least 55 isolated consortia presented reduction in surface tension (ST) and emulsifying activity (EI24). After colony purification, bacteria were submitted to polyphasic analysis assays that resulted in the identification of different strains of cultivable Gammaproteobacteria Gram (−) Citrobacter, Enterobacter, Erwinia, Pseudomonas, Vibrio, Shewanella, Thalassospira, Idiomarina, Pseudoalteromonas, Photobacterium, and Gram (+) Staphylococcus, Bacillus, and Microbacterium. Overall, the best results for ST reduction and EI24 were obtained with consortia. Individually, Pseudomonas, Bacillus, and Enterobacter strains showed the best results for the reduction of ST after 6 days, while Thalassospira and Idiomarina strains showed the best results for EI24 (above 68% after 9 days). Consortia isolates from the GOM had the ability to degrade crude oil by up to 40–80% after 24 and 36 months, respectively. In all cases, biodegradation of crude oil was related to the reduction in ST and bioemulsifying activity and was independent from the depth in the water column.
