HOUSTON, March 10, 2026 — Global energy technology company SLB (NYSE: SLB) announced today that its OneSubsea™ joint venture has been awarded an engineering, procurement, and construction (EPC) contract by PTTEP Sabah Oil Limited, a subsidiary company of PTT Exploration and Production Public Company Limited (PTTEP). The contract expands SLB OneSubsea's role in delivering integrated subsea production systems (SPS) for PTTEP's deepwater portfolio offshore Malaysia and marks the third major SPS award from PTTEP in the last 12 months.

As part of the EPC contract, SLB OneSubsea will deliver comprehensive SPS equipment for the second development of Kikeh 3B project, including three subsea trees, a manifold, a subsea distribution unit and integrated control systems, along with project management and associated services. Project execution will run through 2026 and 2027, supported by SLB OneSubsea's manufacturing and services facilities in Malaysia.

“Building on our long-standing collaboration with PTTEP, this award supports the next phase of the development of Malaysia’s deepwater resources,” said Mads Hjelmeland, chief executive officer of SLB OneSubsea. “With more than two decades of experience supporting PTTEP’s subsea projects, our team is well positioned to deliver safe, efficient and integrated execution across all three recent contract awards.”

The Kikeh field —Malaysia’s first deepwater oil and gas development — has been in production since 2007, when the first subsea tree manufactured by SLB OneSubsea in Malaysia was deployed.

Today, SLB OneSubsea continues to work alongside PTTEP to expand production, at water depths of 1,300-1,400 meters, while increasing local manufacturing of high-value subsea equipment and systems, strengthening local supply chains and building expertise and capabilities in the region.
