Episode 29: Dig boi dig in the Sagar of Assam Oil

History is witness to the fact that discoveries of minerals have changed the course of nations. The discovery of oil in Digboi by the British colonial empire was one such event that gradually altered the economic and political landscape of Assam. In this episode, I survey two (of the four) oil refineries in Assam: the Guwahati Refinery (India's first public sector refinery); and the Numaligarh Oil Refinery (also known as the Assam Accord Refinery).  I also survey ONGC's Assam Assets and the nearby town of Nazira, which I think is still waiting to reap the benefits of the boon of oil in Upper Assam.
