Crude oil production during April-September was 16.37 million tonnes, 5.96% lower than a year earlier.
ONGC, the country’s largest producer of oil and gas, produced 10.25 million tonnes, 3.97% less than a year earlier. An increase in water cut in some fields, pipeline issues, and other technical problems contributed to production decline at ONGCNSE -1.80 %, as per the oil ministry’s monthly report on oil production.
Oil India’s output contracted 4.24% from a year earlier to 1.61 million tonnes.
Production from fields operated by private players contracted at a much faster clip, with output falling 10.74% to 4.5 million tonnes. Vedanta’s Mangla, Bhagyam and Aishwarya fields in Rajasthan underperformed due to several operational issues.
Natural gas output was 16 billion cubic meters, 1.5% less than in the first half of last year.
ONGC’s gas output fell 0.45% to 12.07 billion cubic meters due to a general decline in output from aging fields, a fire incident at Uran plant in September, and less offtake by some clients. Gas production from fields operated by private players contracted 11.22% to 2.54 billion cubic meters.
