ONGC to store CO2 in depleted wells at Gandhar, Pg13

Key Highlights:

• ONGC will launch its first full-scale Carbon Capture and Storage (CCS) pilot project at Gujarat's Gandhar oilfield.
• The pilot aims to inject approximately 100 tonnes of CO2 per day into depleted onshore wells.
• CO2 will be sourced from industrial units near Dahej and ONGC's Hazira plant.

Detailed Insights:

• This CCS project is a significant step in ONGC's decarbonisation strategy, aligning with global efforts to reduce carbon emissions.
• The project utilizes two abandoned onshore wells for CO2 injection into subsurface hydrocarbon reservoirs, preventing atmospheric release.
• Carbon capture from industrial sources and ONGC's Hazira plant demonstrates a collaborative approach to environmental sustainability.

Scientific/Technical Concepts Involved:

• Carbon Capture and Storage (CCS): Technologies that capture CO2 emissions from sources and store them to prevent release into the atmosphere.
• Decarbonisation: The process of reducing carbon emissions from various sources to mitigate climate change.
• Subsurface Hydrocarbon Reservoirs: Underground geological formations that previously held oil and gas, now used for CO2 storage.
