The deep biosphere is the largest microbial biome on the planet. Being remote, difficult to sample and refractory to direct observation it can often seem esoteric and detached from practical relevance. Those working in the oil and gas industry know from difficult and costly experience, that this view of the deep biosphere could not be further from the truth. Petroleum systems provide the most tangible evidence that the deep biosphere should not be relegated to a curious scientific oddity. The operational and economic consequences of microbial activity in petroleum systems are immense and testament to the power of the deep biosphere and its very direct impact on human activities.
Petroleum reservoirs harbor a diverse array of microorganisms, which on production and geological timescales, influence the properties and quality of emplaced oil, affect its production and ultimately its value. Heavy oil formation over tens of millions of years, sulfide formation leading to souring, microbially influenced corrosion and the potential to enhance oil recovery, all have a central microbiological component and in some cases there may be microbiological solutions to detrimental processes that occur during petroleum production. The microbiology of the petroleum deep biosphere will be explored with particular emphasis placed on the activities they catalyze, and factors that may control microbial activity and underline the practical importance of microorganisms, for good or ill, in the oil and gas industry.
