摘要： Methods, computer-readable media, and systems for determining oil viscosity based on biodegradation are described. A chemical signature of oil obtained from a subterranean zone is received. An amount of bacteria associated with oil in the zone based on the chemical signature of the oil is received. Using an empirical relationship relating oil viscosities to amounts of bacteria, an oil viscosity that is empirically related to the amount of bacteria is identified. The identified oil viscosity for the oil is provided, for example, in response to input requesting oil viscosity.

摘要： A method of identifying hydrocarbon seeps that are connected to hydrocarbon reservoirs and for identifying in situ conditions of hydrocarbon reservoirs is disclosed. The method comprises, obtaining a sample from an area of interest, such as a sediment sample or water column sample near a hydrocarbon seep; analyzing the sample to detect microbial signatures that are specific to families associated with hydrocarbon reservoirs; and using the signature to determine whether the hydrocarbon seep is connected to a hydrocarbon reservoir and to identify properties of the hydrocarbon reservoir.

摘要： Method of modeling the biodegradation of hydrocarbons trapped in an oil reservoir or trap through the action of the bacterial population in an underlying aquifer.From data relative to the reservoir studied, concerning the form and the height of the reservoir, the physical characteristics of the porous medium, the thickness of the transition zone between the hydrocarbons and the water, the composition of the hydrocarbons, of the flow of electron acceptors entering the reservoir and data relative to the bacterial population in the aquifer, modeling is performed by discretizing the reservoir by means of a grid wherein the height of each grid cell is the thickness of the transition zone, and the variation, over the height of the reservoir, of the proportion in heavy fractions of hydrocarbons under the effect of the biodegradation is determined by iterative adjustment in each grid cell of the bacterial population to the amount of hydrocarbons available, the pore space available, the amount of electron acceptors present in the reservoir and the degradation capacities of said population.Applications: determination of the composition of oils in a reservoir and notably of the location of the heaviest fractions.

摘要： Methods are provided for detection of souring or the likelihood of souring in an oil and gas process fluid which involves analysis of an aqueous sample obtained from an oil and gas process fluid for the presence of bacteria of at least two different bacterial genera, wherein the genera are selected from Pelobacter, Flexistipes, Marinobacterium, Geoalkalibacter, and Halanaerobium. The presence of bacteria from two or more said genera indicates the likelihood of increased sulfide production in the fluid. Other related methods and reagent compositions for performing the methods are provided.

摘要： A computer supported method, computer system and computer program product for exploring and producing a subsurface heterogeneous hydrocarbon source and generating a predictive production map of an area under investigation, based on microbial prospecting. Microbial data representative of microbial activity attributable to hydrocarbon microseepage and hydrocarbon productivity data of a plurality of geographic locations are retrieved and correlated by the computer in a data correlation algorithm, providing a threshold hydrocarbon productivity quantity and a truncated set of the retrieved microbial data. The set identifies individual types of the microorganisms and corresponding individual weighting factors computed by the data correlation algorithm, for distinguishing prospective hydrocarbon productivity quantities from non-prospective hydrocarbon productivity quantities. An estimated subsurface hydrocarbon productivity quantity for a geographical location of the area under investigation is provided by count weighting retrieved microbial data of this location for microorganisms identified in the truncated set, applying the individual weighting factors.

摘要： Computer-implemented method of determining a composition of hydrocarbons present in a sedimentary basin as a result of biodegradation.The displacement rates of the hydrocarbons and the displacement rates of the water present in the porous medium are estimated, from a genesis time in a mother rock to a possible accumulation in a reservoir rock. The biodegradation in the entire porous medium is then modelled as a function of time, from the genesis in the mother rock, considering that the hydrocarbon composition varies proportionally to the displacement rates.
