Oil and Natural Gas Corporation (ONGC) plans to store captured carbon dioxide in depleted wells at Gujarat's Gandhar oilfield, marking the company's first full-scale Carbon Capture and Storage (CCS) pilot and a major step in its decarbonisation strategy. The pilot will use two abandoned onshore wells to inject around 100 tonnes of CO2 per day into subsurface hydrocarbon reservoirs, officials said. CO2 will be captured from nearby industrial sources in the Dahej area as well as ONGC's own Hazira plant, transported to the Gandhar wells and injected underground to prevent it from entering the atmosphere. The project also aims to test using CO2 to enhance oil recovery, turning a potentially harmful greenhouse gas into a productive resource, they said. ONGC had previously sourced CO2 from Indian Oil Corporation's Koyali refinery, roughly 80 km away, for injections into the well. CO2 in the earth's atmosphere contributes significantly to global warming as a greenhouse gas. India is the 3
