Mubadala Energy Confirms Discovery Of 2nd Gas Field In Indonesia

The South Andaman Gross Split PSC is operated by Mubadala Energy, a multinational energy firm with its headquarters located in Abu Dhabi. Today, the business announced the finding of another significant gas field from the Tangkulo-1 Exploration well, which was drilled in South Andaman, approximately 65 kilometres offshore of North Sumatra, Indonesia. This discovery is the company's second deep-water well that it operates. In a few months, Tangkulo-1 was drilled to 3,400 metres in 1,200 metres of water, following the significant finding at the Layaran-1 well in South Andaman.

Mansoor Mohammed Al Hamed, CEO, of Mubadala Energy, commented: “When added to our recent success at Layaran-1, this game-changing discovery promises to transform Indonesia’s and Southeast Asia’s energy landscape and demonstrates that South Andaman is one of the world’s most exciting energy plays. By working with partners and harnessing our world-class technical capabilities, I am confident we can realize the full potential of this block, in line with our commitment to support the government’s ambitious development timeframes. This news also strengthens our ability to play a proactive role in the energy transition through our gas-biased strategy.”

The Tangkulo-1 well has made a significant gas discovery, encountering an 80-meter gas column within a high-quality Oligocene sandstone reservoir. This discovery was confirmed through a comprehensive data collection effort, including core sampling of 72 meters, wireline logging, sidewall core analysis, as well as pressure and fluid sampling. Utilizing an innovative Drill Stem Test (DST) design, the well achieved a flow rate of 47 million standard cubic feet per day (mmscf/d) of high-quality gas along with 1,300 barrels of condensate. Despite limitations posed by testing facilities, the well's potential is estimated to be between 80 to 100 mmscf/d of gas and over 2,000 barrels of condensate. Mubadala Energy, holding an 80% working interest in South Andaman, stands as the largest acreage holder in the region. This discovery aligns with the company's focus on gas resources, positioning Tangkulo-1 as a key asset in the area's development. Furthermore, the discovery hints at substantial untapped gas resources in neighbouring structures, potentially adding multi-trillion cubic feet (TCF) of gas reserves to the region. In conjunction with the Layaran-1 discovery, Tangkulo-1 contributes significant contingent resources and sets the stage for Mubadala Energy's sustained growth in the area. The company plans to capitalize on this success through further exploration and appraisal activities, reinforcing its commitment to organic expansion in the region.
