New Delhi: Cairn India has revised upward the reserves in Mangala oilfield in Rajasthan by 20% and said plateau production from the biggest of finds in the state will increase by 25% to 125,000 barrels per day.
Mangala is the biggest oilfield in the Rajasthan block which Cairn wants to put into production by the second half of 2009. The company is developing Mangala, Bhagyam and Aishwariya (MBA) fields in the block to produce a combined peak rate of 175,000 bpd of oil.
“The company has submitted a revision to the Mangala field development plan upward revision of 2P to 1,293 million barrels, an increase of more than 20% from the earlier estimates,” Cairn said in its operational updates.
While Mangala alone will contribute 125,000 bpd of peak oil, Bhagyam is the second biggest field in the block and will produce 40,000 bpd of oil.
“Once gross plateau rates of 175,000 bpd from the MBA fields are achieved in Rajasthan, Cairn will contribute more than 20% of India’s daily oil production,” it said.
All major contracts for equipment, long lead time items and civil and construction work for the MBA field development have been placed.
Cairn is working on Enhanced Oil Recovery (EOR) techniques to extend and enhance plateau production.
“We expect that the EOR techniques will lead to a potential to recover additional resources of more than 300 million barrels of oil,” Cairn India CEO Rahul Dhir said in the announcement.
Field trials of EOR methods would start in second half of 2009 to recover additional resources of over 100-200 million barrels from the Mangala field, he added.
