A few months later, it was converted into an Oil and Natural Gas Directorate. The Directorate was converted into Commission and christened Oil & Natural Gas Commission on 14th August 1956.
“Not only had India..set up her own machinery for oil exploration and exploitation… an efficient oil commission had been built where a large number of bright young men and women had been trained and they were doing good work” said Pandit JawaharLal Nehru, India’s first Prime Minister to Lord Mountbatten, on ONGC in 1959.
