Thailand’s PTTEP has taken FID on its first greenfield development offshore Malaysia, the SK405B project.

The development in the SK405B production sharing contract offshore Sarawak covers the Chenda and Sirung oil fields, to be produced via a new central processing platform and a wellhead platform. Facilities will be engineered for zero routine flaring and remotely operated offshore operations. 

First oil should follow in 2028 with a combined production capacity from the fields of about 15,000 bbl/d.

PTTEP Sarawak Oil is the operator, in partnership with PETRONAS Carigali and Mitsui Energy Development Co.

At present, PTTEP is actively involved in more than 10 projects in Malaysia in various exploration, development and production phases.

Offshore Thailand, the company recently increased natural gas sales from the Arthit Field, with production rising from 280 to 330 MMcf/d to help serve domestic gas needs.

The company also secured a 10-year extension to the production period for the Contract 4 Project offshore Block B12/27, which now runs through 2038. This is one of Thailand’s key petroleum resources, the company added in a results statement.
