New Delhi: Cairn India reported seven per cent drop in second quarter production from its flagship Rajasthan oilfields, mainly due to a shutdown at the fields to carry out maintenance work.

Rajasthan block production in July-September stood at 163,262 barrels of oil per day as compared to 175,478 bpd a year ago, the company said in a statement here.

"At Rajasthan, we successfully completed the planned shutdown announced in Q1, for routine operational and statutory maintenance activity at the Mangala Processing Terminal, which resulted in lower production of 163,262 bpd," it said. Cairn said production is back to normal levels in the current quarter. "We are back to normal production levels at Rajasthan after the shutdown; excluding the shutdown period, Q2 production was comparable to Q1.

We also utilised this opportunity to tie-in new facility enhancements related to development projects," the statement said. Output from Ravva oil and gas field off the Andhra coast slipped 29 per cent to 20,596 boepd as "gas sales have been suspended since July 4, 2014 on account of one of the customers undertaking a major unplanned maintenance activity within their Andhra Pradesh pipeline network."

It holds 22.5 per cent stake in offshore Ravva fields, ONGC holds 40 per cent, while Petrocon India and Singapore-based Ravva Oil have 25 per cent and 12.5 per cent, respectively.
