SLB has secured multiple offshore drilling services contracts from Mubadala Energy for the Tangkulo natural gas deepwater development and associated exploration and appraisal drilling in the Andaman Sea, offshore Indonesia.
Under the awards, SLB will provide integrated drilling and well services spanning the full well life cycle. The scope includes directional drilling, drilling fluids, cementing, wireline, slickline, coiled tubing, well testing, mud logging, and upper and lower completions. The integrated delivery model is designed to streamline execution while enhancing safety, reliability and operational performance.
Mubadala Energy said the work supports the responsible and efficient development of Indonesia’s offshore resources, with first gas targeted before the end of 2028. The company described Tangkulo as a cornerstone project in its Southeast Asia portfolio, linking the development to Indonesia’s long-term energy security and economic growth.
The project will leverage SLB’s offshore and deepwater technologies, including real-time downhole monitoring, to reduce operational risk, improve well placement and strengthen project economics. SLB said disciplined execution and integrated delivery are essential for deepwater developments, and that combining advanced drilling technologies, real-time insights and local expertise will support safe and efficient operations while accelerating progress toward first gas.
The contracts were awarded through a competitive tender process, underscoring the strategic importance of the Tangkulo development to Indonesia’s long-term energy security.
