In April 1909, D'Arcy was appointed a director of the newly founded Anglo-Persian Oil Company (APOC), which would later become British Petroleum (BP). By 1911, APOC had run a pipeline from the find to a refinery at Abadan. In 1912, the Mount Morgan company was listed in London, and D'Arcy was made chairman of that board.
