BG's has sold its stake in Block 9A in the Gulf of Thailand to the Tantawan joint venture, which is led by ChevronTexaco. The block is a small concession area, however, it does have some gas reserves. ChevronTexaco is operator of the neighboring Tantawan field in the Gulf of Thailand. In June 2001, Thailand and Cambodia signed a Memorandum of Understanding to conclude an agreement for the joint development of the hydrocarbons in a Joint Development Area, including Blocks 7, 8 and 9. A small portion of Block 9 (referred to as Block 9a) is no longer disputed.
The deal to acquire BG's stake in this field was concluded earlier this month.
