  • Patent number: 8753867
    Abstract: Method of evaluating the biodegradation, through the action of a bacterial population, of hydrocarbons trapped in a geologic structure. The mass of hydrocarbons present in said structure is determined without taking account of the biodegradation, from data relative to the physical and geometrical characteristics of the structure studied. Then the mass of hydrocarbons consumed by biodegradation is calculated after evaluating the number of bacteria, their hydrocarbon consumption and the structure filling time. The mass percentage of oil disappeared through the bacterial action is deduced from these two masses. Application: determination of the composition of oils in a reservoir and notably location of heavy oils. The method can notably be applied to the evaluation of the economic risk linked with the presence of biodegraded petroleum reservoirs.

  • Publication number: 20080286855
    Abstract: An isolated microbial consortium is described that includes a first microbial consortium having Thermacetogenium phaeum to metabolize a complex hydrocarbon substrate into metabolic products comprising an acetate compound. The consortium also includes a second microbial consortium having a methanogen to convert the acetate compound into a final product that includes methane. Also, a method of increasing production of materials with enhanced hydrogen content. The method includes isolating Thermacetogenium phaeum from geologic formation water, culturing the isolated Thermacetogenium phaeum to increase the Thermacetogenium phaeum population, and introducing a consortium of the cultured Thermacetogenium phaeum, which may include spores of Thermacetogenium phaeum, into a hydrocarbon formation containing a complex hydrocarbon substrate.

  • Patent number: 7442305
    Abstract: Disclosed herein is a method for the removal of petroleum hydrocarbon and toxic constitutes from contaminated soils and sediment. The method comprises the removal of contaminated materials from soils and performs bioremediation for the removed contaminated materials in an efficient mode. The remained contaminated materials in the soils are biologically stabilized to allow microorganisms to grow and to consume the remained contaminated materials in the soils.

  • Patent number: 7416882
    Abstract: A method of biotreating a solid material to remove an undesired compound using a nonstirred surface bioreactor is provided. According to the method, the surface of a plurality of coarse substrates is coated with a solid material to be biotreated to form a plurality of coated coarse substrates. The coarse substrates have a particle size greater than about 0.3 cm and the solid material to be biotreated has a particle size less than about 250 ?m. A nonstirred surface reactor is then formed by stacking the plurality of coated coarse substrates into a heap or placing the plurality of coated coarse substrates into a tank so that the void volume of the reactor is greater than or equal to about 25%. The solid material is biotreated in the surface bioreactor until the undesired compound in the solid material is degraded to a desired concentration.

  • Patent number: 7354516
    Abstract: This invention is a system and method for bioremediation of hydrocarbon and organic pollution in fresh and salt water. Hydrocarbon and organic pollution digesting microbes are placed in a floating carrier where the microorganisms are exposed to the pollution and the pollution is digested. The floating element may be a block of polymeric foam. The microbes may be supported on powder such as clay minerals, and the powder may be formed into pellets held in slits in the foam.

  • Patent number: 7124817
    Abstract: A method of treating a hydrocarbon-bearing measure such as an oil-bearing rock formation (13). The method comprises: injecting water containing a source of vitamins, phosphates and an electron acceptor such as nitrate into the formation at first location (10) and allowing anaerobic bacteria, which are either already present in the formation (13) or which are introduced simultaneously to multiply using the oil as their main carbon source. This establishes a biomass layer (16) which acts to dissociate the oil from the rock formation (13). The dissociated oil is removed via an outlet (15). The vitamins are supplied by means of a controlled-release medium.
