The cost of leasing rigs has climbed to records, nearing 500,000 US dollars a day for the biggest structures, as oil exploration companies move to deeper waters in search of new oil and gas reserves after crude oil prices rose to all-time highs.

The discoveries would increase the country's reserves by 134.6 million barrels of oil and 3.6 trillion cubic feet of natural gas this year to 8.3 billion barrels and 184 trillion cubic feet, BP Migas said. The oil and gas findings are about 5 percent higher than those in 2004.
The country pumped 1.061 million barrels of crude oil
