摘要
(WO2019/191370) Methods of enhancing oil recovery may include accessing a consortium of microorganisms in a geologic formation that includes oil. The methods may include delivering an aqueous material incorporating dissolved hydrogen to the consortium of microorganisms. The methods may include increasing production of gaseous materials by the consortium of microorganisms. The methods may also include recovering oil from the reservoir.

(WO2019/191370) WHAT IS CLAIMED IS: 1. A method of increasing oil recovery from a reservoir, the method comprising:   accessing a consortium of microorganisms in a geologic formation that includes oil;   delivering an aqueous material incorporating dissolved hydrogen to the consortium of microorganisms;   increasing production of gaseous materials by the consortium of microorganisms; and   recovering oil from the reservoir. 2. The method of increasing oil recovery from a reservoir of claim 1, wherein the gaseous materials improve oil flow diversion within the reservoir. 3. The method of increasing oil recovery from a reservoir of claim 1, wherein the gaseous materials comprise methane. 4. The method of increasing oil recovery from a reservoir claim 1, wherein the aqueous material comprises water with a dissolved hydrogen content above or about 100 pMoles hydrogen per liter of aqueous material. 5. The method of increasing oil recovery from a reservoir of claim 4, wherein the dissolved hydrogen content is maintained below a saturation concentration for hydrogen. 6. The method of increasing oil recovery from a reservoir of claim 4, wherein the dissolved hydrogen content is maintained below 50% gas saturation for the aqueous material. 7. The method of increasing oil recovery from a reservoir of claim 1, wherein the aqueous material further comprises incorporated metals. 8. The method of increasing oil recovery from a reservoir of claim 7, wherein the incorporated metals include one or more of cobalt, copper, manganese, molybdenum, nickel, tungsten, and zinc. 9. The method of increasing oil recovery from a reservoir of claim 1, wherein the aqueous material further comprises yeast extract. 10. The method of increasing oil recovery from a reservoir of claim 1, wherein delivering the aqueous material comprises injecting the aqueous material at a pressure greater than or about 3.4 MPa. 11. The method of increasing oil recovery from a reservoir of claim 1, wherein a temperature of the aqueous material as delivered is maintained at greater than or about 25° C. 12. A method increasing oil recovery from a reservoir, the method comprising:   accessing microorganisms in a geologic formation that includes oil;   detecting a decrease in a production rate of methane from the reservoir that is indicative of a rollover effect;   injecting an aqueous fluid into the reservoir, wherein the aqueous fluid is characterized by a dissolved hydrogen concentration of greater than or about 100 pMoles hydrogen per liter of aqueous fluid;   increasing methane production within the reservoir to a level greater than an inflection point where the rollover effect began to occur; and   recovering oil from the reservoir. 13. The method increasing oil recovery from a reservoir of claim 12, wherein the methane improves oil flow diversion within the reservoir. 14. The method increasing oil recovery from a reservoir of claim 12, wherein the dissolved hydrogen concentration is maintained below or about 5,000 pMoles hydrogen per liter of aqueous fluid. 15. The method increasing oil recovery from a reservoir of claim 12, wherein delivering the aqueous fluid comprises injecting the aqueous fluid at a pressure greater than or about 7 MPa. 16. The method increasing oil recovery from a reservoir of claim 12, wherein a temperature of the aqueous fluid as injected is maintained at greater than or about 25° C. 17. The method increasing oil recovery from a reservoir of claim 12, wherein native water within the reservoir is characterized by a sulfate concentration below or about 100 mg per liter of native water. 18. The method increasing oil recovery from a reservoir of claim 12, wherein the aqueous fluid further comprises incorporated metals. 19. The method increasing oil recovery from a reservoir of claim 12, wherein the aqueous fluid further comprises yeast extract. 20. The method increasing oil recovery from a reservoir of claim 12, wherein the aqueous fluid as injected provides a delivery rate of hydrogen between about 5 standard cubic centimeters of dissolved hydrogen per liter of aqueous fluid and about 40 standard cubic centimeters of dissolved hydrogen per liter of aqueous fluid.
