Rapid microbial methanogenesis during CO₂ storage in hydrocarbon reservoirs.

ABSTRACT: Carbon capture and storage (CCS) is a key technology to mitigate the environmental impact of carbon dioxide (CO₂) emissions. An understanding of the potential trapping and storage mechanisms is required to provide confidence in safe and secure CO₂ geological sequestration^1,2. Depleted hydrocarbon reservoirs have substantial CO₂ storage potential¹,³, and numerous hydrocarbon reservoirs have undergone CO₂ injection as a means of enhanced oil recovery (CO₂-EOR), providing an opportunity to evaluate the (bio)geochemical behaviour of injected carbon. Here we present noble gas, stable isotope, clumped isotope and gene-sequencing analyses from a CO₂-EOR project in the Olla Field (Louisiana, USA). We
