Oil India, which reported a record-high profit of Rs 6,810 crore for 2022-23, increased its oil production by 5.5% to 3.18 million metric tonnes (mmt) and gas output by 4.4% to 3.18 billion cubic meters (bcm) during the year. The growth is on top of the output expansion that has gone into offsetting the natural decline in matured fields, chairman and managing director Ranjit Rath said.
