PTTEP reports that the exploration well, Zawtika 1A, spudded on December 4, 2006 was drilled to a total depth of 3,567 meters and encountered natural gas bearing formation. Three flow rate testing (Tubing Stem Test*-TST) were conducted. The first test indicated a natural gas maximum flow rate of approximately 32 million standard cubic feet per day (MMSCFD). The second test indicated a maximum natural gas flow rate of approximately 26.6 MMSCFD and the third test indicated a maximum natural gas flow rate of approximately 12.8 MMSCFD. The successful combined flow rate of 71.4 MMSCFD confirms the future potential core development area in block M9.

To estimate the petroleum reserves and prepare a development plan for future production, PTTEP will continue to drill seven more exploration and delineation wells in this block which are expected to be finished in July 2007.

Tubing Stem Test (TST) is a flow rate testing technology in which PTTEP has developed from technology in the Gulf of Thailand to firstly apply on the floater. The result of using TST on the floater helps reducing time consumed and drilling cost. The company believes that this TST on floater is "The First Tubing Stem Test on Floater ever".

Mr. Maroot Mrigadat, President of PTTEP, said "The find is not only good for Thailand, but for Myanmar as well. We will drill more exploration and delineation wells in this block this year to estimate the petroleum reserves and we look forward to preparing a development plan for future production."

PTTEP International Limited (PTTEPI), a 100% owned subsidiary of PTTEP, is an operator of exploration block, M9, in Myanmar. The block is located in the Gulf of Mataban, about 250-300 kilometers south of Yangon.
