The injection of CO2 into deep saline reservoirs is an important greenhouse gas mitigation strategy. In many cases, the CO2 source is made up of a mixture of different greenhouse gases. One such case is at the Otway International Test Center in Australia, where the source of CO2 comes from a natural gas reservoir made up of a mixture of methane (CH4) and CO2. Both CO2 and CH4 are soluble in...

Carbon sequestration and hydrogen storage at large scales require suitable subsurface formations, with shale playing critical roles in both scenarios. In conventional reservoirs, shale acts as a caprock, preventing the upward migration of injected gases. In unconventional reservoirs, hydraulically stimulated shale contributes to storage by providing fractures, cracks, and pore spaces.
