“…Thermococcus and its close relative Pyrococcus were the predominant archaea detected 634 and 1626 m below the seafloor (mbsf) in sediment cores collected offshore of New Zealand and Newfoundland, Canada respectively (Roussel et al, 2008;Ciobanu et al, 2014). Thermococcus were also the predominant archaea found in an uncontaminated oil reservoir 2500 mbsf in the Norwegian Sea and in a 908C water-flooded oil well in China (Lewin et al, 2014;Lin et al, 2014). Furthermore, Thermococcus bloomed in Marcellus and Utica shale bed produced waters in western Pennsylvania, USA seven days after hydraulic fracturing (Daly et al, 2016).…”

Some hyperthermophilic heterotrophs in the genus Thermococcus produce H in the absence of S° and have up to seven hydrogenases, but their combined physiological roles are unclear. Here, we show which hydrogenases in Thermococcus paralvinellae are affected by added H during growth without S°. Growth rates and steady-state cell concentrations decreased while formate production rates increased when T. paralvinallae was grown in a chemostat with 65 µM of added H . Differential gene expression analysis using RNA-Seq showed consistent expression of six hydrogenase operons with and without added H . In contrast, expression of the formate hydrogenlyase 1 (fhl1) operon increased with added H . Flux balance analysis showed H oxidation and formate production using FHL became an alternate route for electron disposal during H inhibition with a concomitant increase in growth rate relative to cells without FHL. T. paralvinellae also grew on formate with an increase in H production rate relative to growth on maltose or tryptone. Growth on formate increased fhl1 expression but decreased expression of all other hydrogenases. Therefore, Thermococcus that possess fhl1 have a competitive advantage over other Thermococcus species in hot subsurface environments where organic substrates are present, S° is absent and slow H efflux causes growth inhibition.

“…Most studies exploring microbial communities use culture-based methods to recover and identify individual oildegrading isolates and do not provide complete information of how these communities are structured. Nevertheless, as a general "rule of thumb" thermophilic anaerobic bacteria (Thermotoga, Thermoanaerobacter, Thermodesulfobacterium), hyperthermophilic archaea (Thermococcus, Thermofilum) and hydrogenotrophic methanogenic archaea (Methanothermococcus, Methanobacterium, Methanoculleus) are commonly the predominant microorganisms found in high temperature oil reservoirs and their diversity might be reduced at higher temperature (>80-90 • C) and salinity conditions (>100 g/l) (Orphan et al, 2000(Orphan et al, , 2003Dahle et al, 2008;Lin et al, 2014). Mesophilic bacteria, such as Clostridium, Pseudomonas, Arcobacter, Geobacter, Desulfuromonas, Marinobacter, and others, can also be found in high abundances in lower temperature oil reservoirs (Hubert et al, 2012;Zhang et al, 2012;Okpala et al, 2017).…”

The depletion of oil resources, increasing global energy demand, the current low, yet unpredictable, price of oil, and increasing maturity of major oil fields has driven the need for the development of oil recovery technologies that are less costly and, where possible, environmentally compatible. Using current technologies, between 20 and 40% of the original oil in a reservoir can be extracted by conventional production operations (e.g., vertical drilling), with secondary recovery methods yielding a further 15-25%. Hence, up to 55% of the original oil can remain unrecovered in a reservoir. Enhanced oil recovery (EOR) is a tertiary recovery process that involves application of different thermal, chemical, and microbial processes to recover an additional 7-15% of the original oil in place (OOIP) at an economically feasible production rate from poor-performing and depleted oil wells. EOR can significantly impact oil production, as increase in the recovery rate of oil by even a small margin could bring significant revenues without developing unconventional resources. Microbial enhanced oil recovery (MEOR) is an attractive, alternative oil recovery approach, which is claimed to potentially recover up to 50% of residual oil. The in situ production of biological surface-active compounds (e.g., biosurfactants) during the MEOR process does not require vast energy inputs and are not affected by global crude oil prices. Compared to other EOR methods, MEOR can be an economically and more environmentally friendly alternative. In this review, the current state of knowledge of MEOR, with insights from discussions with the industry and other stakeholders, is presented and in addition to the future outlook for this technology.

“…Detecting microbes involves complex high-tech biotechnology, such as terminal restriction fragment length polymorphism (T-RFLP) [11,16,23,30], gene bank [31], denaturing gradient gel electrophoresis (DGGE) [30], and most probable number (MPN) [32], which are beyond the scope of this paper. Microbial community structures and diversity characterization in Shengli Oilfield by such technologies are well documented [30,33]. Figure 8 [33] shows microbe diversity in the second largest oil production reservoir in China.…”

“…flooding indeed improved oil recovery. For potential reservoir screening consideration, reservoir parameters and MFR field test performance are summarized in Table 6 from various references [30,33,60,64,65]. After air-assisted MFR, the annual water cut increase rate changed from 9% to 0.53%, and it has been maintained lower than 1.5% for 8 years [14].…”

Compared with other enhanced oil recovery (EOR) techniques like gas flooding, chemical flooding, and thermal production, the prominent advantages of microbial enhanced oil recovery (MEOR) include environment-friendliness and lowest cost. Recent progress of MEOR in laboratory studies and microbial flooding recovery (MFR) field tests in China are reviewed. High biotechnology is being used to investigate MFR mechanisms on the molecular level. Emulsification and wettability alternation due to microbial effects are the main interests at present. Application of a high-resolution mass spectrum (HRMS) on MEOR mechanism has revealed the change of polar compound structures before and after oil degradation by the microbial on the molecular level. MEOR could be divided into indigenous microorganism and exogenous microorganism flooding. The key of exogenous microorganism flooding was to develop effective production strains, and difficulty lies in the compatibility of the microorganism, performance degradation, and high cost. Indigenous microorganism flooding has good adaptation but no follow-up process on production strain development; thus, it represents the main development direction of MEOR in China. More than 4600 wells have been conducted for MEOR field tests in China, and about 500 wells are involved in MFR. 47 MFR field tests have been carried out in China, and 12 field tests are conducted in Daqing Oilfield. MFR field test’s incremental oil recovery is as high as 4.95% OOIP, with a typical slug size less than 0.1 PV. The input-output ratio can be 1 : 6. All field tests have shown positive results in oil production increase and water cut reduction. MEOR screening criteria for reservoirs in China need to be improved. Reservoir fluid, temperature, and salinity were the most important three parameters. Microbial flooding technology is mature in reservoirs with temperature lower than 80°C, salinity less than 100,000 ppm, and permeability above 5 mD. MFR in China is very close to commercial application, while MFR as quaternary recovery like those in post-polymer flooding reservoirs needs further study.
