Abstract:
A method for the economic assessment of residual oil zones (“ROZ”), support for the engineering of the design of CO 2  enhanced oil recovery (“EOR”) systems associated with production of petroleum from ROZ, support of EOR operations, and subsequent management and monitoring of CO 2  sequestered in ROZ is disclosed. This efficient identification and assessment of ROZs significantly increases the geographic footprint and target locations into which CO 2  can be injected and ultimately utilized and permanently sequestered in a commercial fashion generating value to partially offset the parasitic costs associated with the capture of anthropogenic CO 2 . Microbial self limitation (MSL) conditions of an ROZ are exploited for the assessment and management purposes of the ROZ.

Claim (Index 1):
A method of development of a ROZ resource comprising:\n quantitatively and qualitatively evaluating how in situ microbial self limitation (MSL) conditions in a residual oil zone (ROZ) govern the microbial processing of petroleum in the ROZ and determining the operations associated with development of the ROZ through a plurality of processes comprising:\n identifying and obtaining one or more samples of media from an ROZ, \n wherein the selected media comprises gas, water, petroleum, mineral matrix and combinations thereof;\n identifying specific microbial consortia and associated metabolic pathways within the one or more samples obtained from the ROZ, wherein identifying the specific microbial consortia and associated metabolic pathways within the one or more samples comprises identification by domain and species and by heterotrophic and autotrophic metabolic pathways; \n determining the effects of microbial processes of the microbial consortia on mineral species within one or more of the samples obtained from the ROZ; \n thereafter determining how in situ MSL conditions govern the microbial processing of petroleum by the microbial consortia in the one or more samples taken from the ROZ to effect biogenic mineral production of amorphous, nano-crystalline and chaotic mineral forms having enhanced reactivity towards CO2 by a process comprising:\n determining the activity of the indigenous or introduced microbial consortia to the presence of petroleum hydrocarbons based on selective degradation and modification of native hydrocarbons species in the one or more samples; \n determining whether the modification of the native hydrocarbon species generates charged or polar species that interact with mineral surface charges to stimulate adsorption of petroleum hydrocarbons to mineral surfaces within the one or more samples; \n determining the effect of biosurfactants on the one or more samples obtained from the ROZ; \n determining the capacity for stimulation of iron reduction by the microbial consortia within the one or more samples; \n determining the effect of sulfate reduction, methanogenic and labile elemental systems, and processes and effects of microbial inhibition that prevent the substantially complete degradation of petroleum in the one or more samples; and \n combinations thereof; \n determining the ability of the amorphous, nano-crystalline and chaotic mineral forms having enhanced reactivity towards CO2 that were effected by the processing of petroleum by the microbial consortia in the one or more samples taken from the ROZ to sequester and store at least some injected CO2; and, \n \n thereafter determining the effects of the microbial consortia on mineral species and the determination of how in situ MSL conditions govern the microbial processing of petroleum by the microbial consortia to effect biogenic mineral production of amorphous, nano-crystalline and chaotic mineral forms having enhanced reactivity towards CO2 within one or more of the samples obtained from the ROZ.
