The South Korean gas company Kogas would purchase liquefied natural gas (LNG) from the Tangguh oil and gas field in Indonesia, Indonesian oil and gas regulator BP Migas said.

Deputy for operation of upstream business activity of the regulator Edy Purnomo said that the agreement on the purchase would be signed in August and the sending of gas would start in 2010.

Purnomo said that the price of the gas was 20 U.S. dollars per million btu (British thermal unit), but the volume of the gas has yet been determined.

He said that the gas to be exported to South Korea would be taken from the quota provided for the U.S. company Sempra in the field.

"We have decided to shift the sales of gas from Sempra to Kogas at the block. There is a clause that should another company pay a higher price, the sales of the gas can be shifted," he was quoted by Bisnis Indonesia daily as saying Thursday.
