Methods and systems for producing organic compounds in a subterranean environment

A method of producing at least one organic compound in a subterranean environment comprising:

• providing a carbon dioxide feedstock, a microbial culture, and a microbial growth medium;
• and
• converting a portion of the carbon dioxide feedstock into the at least one organic compound by adding the carbon dioxide feedstock, the microbial culture, and the microbial growth medium to the subterranean environment, wherein the carbon dioxide feedstock contains from about 1.0 volume percent to 100 volume percent carbon dioxide based on a total volume of the carbon dioxide feedstock;
• and further comprising the steps of:
• collecting a first sample from the subterranean environment at a first time point;
• analyzing the first sample to obtain a first sample microbiome information;
• and
• selecting the microbial culture and the microbial growth medium based on the microbiome information of the first sample to promote the survival and growth of the microbial culture in the subterranean environment, and the production of one or more organic compounds;
• wherein the at least one organic compound includes methanol;
• and
• wherein the microbial culture includes a Geobacter bacterium, a Clostridium bacterium, a Bacillus bacterium, a Geobacillus bacterium, a Petrobacter bacterium, a Desulfotomaculum bacterium, a Bacteroides bacterium, a Thermoanaerobacter bacterium, a Thermococcus bacterium, a Thermotogales bacterium, a Petrotoga bacterium, a Thermotoga bacterium, a Caminicella bacterium, a Geosporobacter bacterium, or a combination thereof.
