Figure 1: Methanogenesis in control and CO2-injected microcosms.
From: Carbon dioxide concentration dictates alternative methanogenic pathways in oil reservoirs
Methanogenesis shown in (a) three individual control microcosms and (b) three individual CO2-injected microcosms under high-temperature and high-pressure conditions (55 °C and 5 MPa). Methane (circles) and acetate (squares) concentrations over time in the unlabeled (closed symbols), [2-13C]-acetate (gray symbols) and 13C-bicarbonate (open symbols)-labeled microcosms. All six microcosms were constructed using high-temperature oil reservoir samples.
