India's crude-oil production fell 2.4% on year in May and natural-gas output continued its declining trend.

Crude oil output fell to 3.17 million metric tons, or 749,550 barrels a day, oil ministry data showed Friday. The government's target was 3.20 million tons.

oil output from state-run Oil & Natural Gas Corp. (500312.BY) fell 0.9% on year to 1.89 million tons--446,893 barrels a day--as high water content and a power shutdown at fields in Gujarat took their toll. Output at its main Mumbai High offshore field was lower than expected.

India imports about 80% of its crude-oil requirement. Natural gas output in India fell 18.7% on year to 3.01 billion cubic meters, missing the government's estimate of 3.19 billion cubic metres.
