“…The higher growth of homoacetogens over SSRM and methanogens results from a lower wet cell mass that causes a lower nutrient demand per cell (see Text A.1). Our calculations are in line with total cell concentrations of 10 5 -10 15 cells/ mL -1 in oil reservoirs [209], and equal to or up to four order of magnitudes higher than cell counts from gas reservoirs (0.001-1.2*10 7 cells mL -1 ) [51,97,185]. The range of the literature data reflects that our simple methodology to calculate microbial numbers may serve as a first approximation to estimating microbial growth in the subsurface, only.…”

Subsurface storage of hydrogen, e.g. in depleted gas or oil fields (DOGF), is suggested as a means to overcome imbalances between supply and demand in the renewable energy sector. However, hydrogen is an electron donor for subsurface microbial processes, which may have important implications for hydrogen recovery, gas injectivity and corrosion. Here, we review the controls on the three major hydrogen consuming processes in the subsurface, methanogenesis, homoacetogenesis, and sulfate reduction, as a basis to develop a hydrogen storage site selection tool. Testing our tool on 42 DOGF showed that seven of the fields may be considered sterile with respect to hydrogenconsuming microbiota due to either temperatures >122 °C or salinities >5 M NaCl. Only three fields can sustain all of the hydrogen consuming processes, due to either temperature, salinity or pressure constraints in the remaining fields. We calculated a potential microbial growth in the order of 1-17*10 7 cells ml-1 for these fields. The associated hydrogen consumption is negligible to small (<0.01-3.2 % of the stored hydrogen). Our results can help inform decisions about where hydrogen will be stored in the future.

“…In the presence of active calcium ions, sulfate ions bound into anhydrite new growth. The formation of pyrite is associated with the biochemical processes of sulfate reduction occurring in oil deposits with the participation of anaerobic microbial colonies [17,18,19]. Secondary minerals complicate the structure of the reservoir pore space, narrowing the intergrain filtration channels.…”

The article discusses the structure of multilayer oil deposits of the Vereyian horizon in the territory of the Tatarstan Republic. It is shown that in the sections the reservoir rocks are different facies of limestones (mostly grainstone), sandstones and siltstones. The reservoir rocks were formed in the regressive stage of the development of the marine sedimentation basin. Oil deposits of the Vereyian horizon have experienced flooding processes with formation edgewater. The penetration of groundwater into reservoir rocks led to uneven oxidation of oils in oil-producing structures. With weak waterflooding, dolomite and pyrite were formed in the reservoir rocks, with strong waterflooding, anhydrite aggregates appear.

“…Physical and chemical remediation are short-term, but still giving bad secondary effects to the environment, and especially physical methods can only remove 10-15% of pollutants from the marine media [5,6]. Bioremediation is a pollution treatment method that is considered more environmental-friendly and effective than other methods to degrade crude oil spills because it uses microorganisms as a degrading agent [7][8][9][10]. The success of bioremediation in treating hydrocarbon-contaminated environments is dependent on the accessibility of pollutants to degrading organisms, the biodegradability of the pollutants and the optimization of biological activity [11].…”

Culture of Bacterium Bacillus subtilis as Degradation Agent in Attempt of Sea Water Remediation Contaminated By Petroleum

Crude oil spills pose a serious threat to the marine environment. This is due to crude oil, in large part, is composed of aromatic, aliphatic, and alicyclic hydrocarbons which are toxic, carcinogenic, and mutagenic to the marine life. However, the degradation of crude oil spills with bacteria in simulated seawater media is rarely reported. In this study, oil spill in the seawater, especially petroleum, had been successfully degraded by bacterium culture Bacillus subtilis in simulated seawater under 7 and 14 days incubation. Simulated seawater had synthesized based on ASTM D1141-98 for Standard Practice for the Preparation of Substitute Ocean Water. The petroleum recovery was analyzed using Gas chromatography-mass spectrometry. In this research, the optimum recovery value of crude oil degradation by the bacterial culture obtained by octadecadienoic acid compound gave a percentage recovery of 8.20% and 8.87% after 7 and 14 days of incubation, respectively. This result indicated that the B. subtilis culture has the ability to degrade crude oil spill in simulated sea water.
