Reportedly, it is widely recognised for its international partnership with the Abu Dhabi National Oil Company (ADNOC), which stores its own oil here.

It is built deep within the granite rocks of Udupi district. Its structural integrity is maintained by natural water table pressure, which prevents oil from leaking out through any rock fissures.

Once completed, it will significantly boost India’s storage on the eastern seaboard. This represents a shift toward a Public-Private Partnership (PPP) model, inviting global players to lease space while bolstering national energy resilience. (Image: isprindia.com)
