ChevronTexaco which acquired Unocal in August 2005 is by far the countrys largest Natural Gas producer and has continued to increase its production with the development of new reserves. The Pailin gas field which came onstream in August 1999 added 165 million cubic feet per day (MMcf/d) to Thailands gas production. Unocal also started production at the Trat field in 1999.  Unocal undertook a second phase of development at its Pailin field beginning in 2002 which brought production to around 330 MMcf/d.
ChevronTexaco is currently producing about 145 MMcf/d from its offshore Block B8/32.  The company has put its estimated gas reserves in the block at 2.5 Tcf and has plans to expand production in the future to about 250 MMcf/d. Amerada Hess reported a new onshore natural gas find in northeastern Thailand in early 2003 which currently is under development. The company expects to begin production from the Phu Horm field in 2006.
The $1 billion 416-mile Thai-Burmese natural gas Pipeline running from Burmas Yadana gas field in the Andaman Sea to an Electricity Generating Authority of Thailand (EGAT) power plant in Ratchaburi province was completed in mid-1999.  A new connecting line also has been built linking Ratchaburi to the Bangkok area which provides for other uses for imported Burmese gas in addition to the Ratchaburi power plant.
