PTTEP is about to spud the Timpani-1 wildcat exploration well in Block SK 438 offshore Sarawak, Malaysia, using the Naga 5 jack-up rig. The operation, supported by three vessels, is expected to be completed in early April.

Exploration Context and Previous Success

This drilling activity follows a geophysical survey and builds upon previous exploration successes in the same block. Block SK 438 contains the 2021 Kulintang-1 gas discovery, which was the first well drilled on the block and proved gas in previously unevaluated Oligocene to Middle Miocene sandstone reservoirs. Subsequent discoveries at the Bangsawan-1 and Babadon-1 wells further confirmed the area's potential, with Babadon-1 revealing substantial sweet gas sandstone reservoirs.

Development Plans and Asset Portfolio

PTTEP, as the operator with an 80% interest, is considering plans for a potential multi-field development in the area. The company's broader Sarawak southern cluster also includes Block SK 405B, which hosts the Sirung and Chenda discoveries. A final investment decision for exploiting these southern cluster discoveries is anticipated in 2026.
