Figure 6

The water ratio, oil recovery ratio, and injection pressure during core-flooding tests: (a) ex situ oil recovery potential of Dietzia sp. ZQ-4 in core test; (b) in situ oil recovery potential of ZQ-4 in the core test accompanied by a nutrient stimulation process. The vertical bars in (a) and (b) indicate the injection of formation brines with fermentation liquor of ZQ-4 and nutrient injection, respectively.
