PTTEP stock rises on Bussabong gas field decision

PTT Exploration and Production Public Company Limited (TH0001010014) closed at THB 150.00 on September 21, 2026, up 32.74 percent since the start of the year. The company has also advanced the Bussabong gas project in the Gulf of Thailand, with first production planned for 2028.

Bussabong moves toward production

According to Bangkok Post on September 22, 2026, PTTEP announced the final investment decision for the Bussabong gas field in Block G3/65. First natural gas production is targeted for 2028, giving the project a multi-year operating contribution rather than an immediate earnings effect.

Manila Times reported on September 22, 2026 that Phase 1 is planned to deliver approximately 30 mmcf/d of sales gas in 2029 and approximately 40 mmcf/d in 2030. The comparison between those two planned production levels represents an increase of approximately 10 mmcf/d, although the schedule remains dependent on development execution and the gas sales agreement.

Stock holds near its yearly range

PTTEP traded at THB 149.50 on September 22, 2026 at 10:01 a.m. GMT+7, down 0.33 percent from the previous close of THB 150.00 on the Stock Exchange of Thailand. The same market snapshot showed a 52-week range of THB 104.00 to THB 164.00 and a market capitalization of THB 593.513 billion.

The price was THB 14.50 below the reported 52-week high and THB 45.50 above the low on September 22, 2026. That positioning leaves the stock closer to the upper end of its annual range, while Bussabong offers a longer-dated production signal rather than a near-term earnings figure.
