Our Operations


Production & Exploration

We have been present in Indonesia since 2004 and operate four offshore Production Sharing Contracts (PSC): In the Makassar Strait the Sebuku PSC with the producing Ruby gas field and the West Sebuku PSC plus offshore Aceh the Andaman I and South Andaman PSCs. We also have a non-operated interest in the Andaman II PSC.

Our Indonesia operation has maintained an excellent safety record with no Lost time Incident (LTI) during development and in production. The Ruby operations have accreditation to the international safety and environmental standards, ISO 14001 and OHSAS 18001.

We have a well-established community investment program partnering with local stakeholders to support the coastal communities in the vicinity of our Ruby operation.


Ruby field

The Ruby gas field supplies reliably and safely gas for the domestic gas market since October 2013. Located in the Makassar Strait, Mubadala Petroleum as operator has a 70 percent interest in the Sebuku PSC with partners TOTAL E&P Sebuku and INPEX South Makassar Ltd each holding a 15 percent interest.

The facilities include a wellhead platform, a production and living quarters platform with the gas being transported via a 312 kilometer subsea pipeline to the onshore processing terminal at Senipah. Gas is delivered to a fertilizer plant owned by the buyer, PT Pupuk Kalimantan Timur. Ruby has achieved over 150 billion cubic feet cumulative gas production to date.

The Ruby project was delivered safely, on time and budget in 2013, 28 months after sanctioning with an investment of approximately US$500 million by the partners.

West Sebuku

Mubadala Petroleum is operator of the West Sebuku exploration block which surrounds the Sebuku PSC, and holds a 75.5 percent interest with INPEX Corporation holding 24.5 percent interest. 3D seismic data was acquired over both blocks in 2014.

The Andaman blocks
