Figure 2: Carbon isotopic ratios of methane in control and CO2-injected microcosms after incubation.
From: Carbon dioxide concentration dictates alternative methanogenic pathways in oil reservoirs
Carbon isotopic ratios of methane in the (a) control microcosms and (b) CO2-injected microcosms after incubation of 103 days. Carbon isotopic ratios of methane and dissolved inorganic carbon (DIC) in each microcosm during incubation are shown in Supplementary Table S2.
