India's upstream oil regulator and largest oil explorer seem to be at war again. While the petroleum ministry wants to give more powers to the regulator, ONGC is not quite happy with that move. NDTV has access to ONGC's note to the petroleum ministry, which opposes the government's move to revive a proposal to give some of its own statutory powers under the Oil Fields (Regulation and Development Act), 1948 and P&NG rules of 1959 to the regulator.
