Abstract:
Controlling microbial growth and activity during Microbial Enhanced Oil Recovery processes is disclosed. Specific control of microbial growth and activity in this process results in prevention of nutrient loss in transit and allows better targeting of microbial activity to the desired subsurface location(s).
