Moving beyond conventional techniques, Oil and Natural Gas Corporation (ONGC) plans to introduce carbon dioxide injection in its Gandhar field to recover an extra 20 million barrels of crude oil under the enhanced oil recovery (EOR) programme which is being undertaken to improve India’s energy security.
ONGC plans to invest $75 million in CO2 capture and another $200 million in injector producer network to recover an extra 15 percent of residual oil currently valued at $1.36 billion. It will be operational in 20 months. Gandhar located in Gujarat is one of ONGC’s major brownfields and was discovered in 1983. The field produces approximately 30,000 barrels of oil per day and is on the decline.
ONGC is in talks with NTPC for utilising nearly 5 million tonnes of emitted gas from the latter’s Gandhar plant. The power utility will provide the land in their project campus as well as power while investments would be from ONGC. NTPC’s gain would be carbon neutrality while the nation would get extra oil.
