A method of increasing oil recovery form a carbonate oil reservoir by determining the presence of microorganisms, determining a specific nutrient package to stimulate the microorganisms, delivering the nutrient package to the carbonate oil reservoir, and allowing the stimulated microorganisms to change the adhesion tension between the carbonate oil rock formation and the oil and the water.

A method of enhancing oil recovery includes the step of determining a specific nutrient package used to initiate a microbiological response under actual reservoir conditions in combination with low salinity water injection. Once determined, the specific nutrient package is applied to at least one targeted well to stimulate resident microorganisms such that size or hydrophobic properties are beneficially altered so that interaction with oil contained in a reservoir rock formation is improved.

A method of monitoring fluid flow in an oil reservoir includes the step of delivering a nutrient package to an oil reservoir. The nutrient package stimulates the growth of resident microbes/organisms which changes the morphology and function of the microbes. A sample is taken from produced fluids from wells in the reservoir and possible connections thereof and analyzed. Based on the analysis, determinations are made regarding the movement of fluids in the reservoir by observing changes in the range, concentration, and cell morphology of the microbes after nutrient stimulation by comparing pre-treatment versus post treatment measurements.

A method for enhancing oil and oil residue recovery from oil-containing rock formations by supplementing a water cycle of a water alternate gas process with nutrients such that the formation resident microorganisms are stimulated as an additional oil release mechanism is provided. The method alters three-phase relative permeability in order to increase displacement efficiency while increasing oil release by microbially assisted water alternate gas processing.

A method of improving oil recovery includes the step of selecting an oil containing rock formation having geologic structures and well completions with vertical permeability that allow a structurally high water injection point. Through a series of analyzes a nutrient water mixture is determined and injected at the injection point to stimulate resident microorganisms through gravity dispersion of nutrient materials. A period of limitation is allowed to permit changes in the size or hydrophobic properties of the microorganisms. Through interaction with the stimulated resident microorganisms, oil, trapped in a pore space, is freed to accumulate with upward gravity separation for production.

A method of increasing oil recovery from oil reservoirs includes the step of conducting a series of lab analysis that lead to a specific nutrient formulation followed by or in parallel with a genetic analysis of resident microorganisms in water produced from an oil reservoir to determine if the population of oil interactive microorganisms may be modified to produce a change in oil-water relative permeability of an oil reservoir. The series of analyzes are conducted to determine the contents of a specific nutrient formulation package to optimize changes in the resident microorganisms to enhance oil recovery by changing oil-water relative permeability in the oil reservoir. Next the specific nutrient formulation is applied to stimulate some of the resident microorganisms to interact with oil contained in the reservoir rock formations. The stimulation step is followed by limiting the specific nutrient formulation to alter or modify the physiology and surface characteristics of the targeted microorganisms.
