The Indonesian government Monday presented a list of 21 oil and gas blocks across the country to foreign and domestic investments.

"We put these 21 blocks on offer for exploration and invite potential investors," Minister of Energy and Mineral Resources Purnomo Yusguantoro said during the 31st Indonesian Petroleum Association conference and exhibition in Jakarta.

The 21 blocks are dispersed from the easternmost province of Papua to the Natuna Sea in western Indonesia.

Speaking on the same occasion, President Susilo Bambang Yudhoyono said the country needs huge investments in the energy sector to tap the major resources which have not been explored.

He said the country's oil production of some 1 million barrels per day remains insufficient to meet domestic demands and the country needs to boost productivity and refinery activities.

"Less than 50 percent of oil wells in Indonesia are managed intensively," he said.
